Abstract 

Heinrich Friedrich August Karl Ludwig Friese (1860–1948) was an important pioneer bee biologist (melittologist). 

Between 1883 and 1939 he described 1,989 new species and 564 new varieties or subspecies of insects, of which over 

99% were bees. His research was global, including description of new taxa from all biogeographical regions where bees 

occur, belonging to all seven extant bee families and 124 genera, including Megachile (with 262 species-group taxa proposed), 

Bombus (232), and Halictus (153). The present catalog provides a complete list of the taxa proposed by Friese, 

including a bibliography of his 270 entomological publications. The catalog lists all valid names proposed by Friese and 

details on the nomenclature, sex, and region of origin of each. The current combination and subgeneric placement are 

cited for taxa now regarded as valid species. A brief biography is followed by a discussion of how to locate and treat 

Friese types, a notoriously complicated issue due to Friese’s confusing labeling practices and the broad dispersion of his 

specimens.

Bees are fundamental components of ecosystems where they provide pollination services for a multitude of 

plants, including crops (Barth 1991; Buchmann & Nabhan 1996; Proctor et al. 1996). Recently reported 

declines in native bee populations (Biesmeijer et al. 2006; National Academy of Sciences 2006; Fitzpatrick et 

al. 2007) are therefore of public concern, and further data on populations are required for evaluating apparent

pollinator declines from historical and global perspectives. Assemblies of such communities can be monitored 

through field observations and collections gathered so as to ascertain the relative abundance of the taxa concerned, 

but this requires accurate identifications. While bees generally can be identified to genus and subgenus 

(e.g., Michener 2000, 2007), identification of the more than 19,000 currently valid bee species (Michener 

2007; Ascher et al. 2008) is less feasible for much of the world, as comprehensive modern revisions exist only 

for certain taxa, and very few bee faunas are as fully characterized as that of central Europe (Schwarz et al. 

1996; Michener 2007). Ready access to reliable names for all described bee species is essential to document 

the global bee fauna, but locating comprehensive species-level nomenclatural data has been a challenge as the 

most recent global bee catalog was published more than a century ago (Dalla Torre 1896).

The single most prolific describer of bees was Theodore Dru Alison Cockerell (1866–1948: Schwarz 

1948; Weber 1965) who described 6,399 new taxa from all biogeographic regions (Zuparko 2007). The only 

other authors of comparable importance are Frederick Smith (1805–1879: Baker 1993) who named some 

1,500 new taxa of bees and Heinrich Friedrich August Karl Ludwig Friese (1860–1948: Figure 1) who proposed 

2,728 new names between 1883 and 1939. No comprehensive treatment of the taxa proposed by Friese 

exists due in part to the difficulty of assembling all of his 270 papers. Type specimens by Friese are distributed 

among an unknown number of repositories where primary type specimens are difficult to identify. Among the 

problems encountered when dealing with Friese types (i.e., specimens with “Typus” or “Type” labels) according 

to the code (International Commission on Zoological Nomenclature 1999) are: 1) Friese did not clearly 

distinguish primary types (holotypes) from secondary types (paratypes), resulting in syntype series; 2) Friese 

labeled homotypes or metatypes with type labels after publication of new taxa, even though they were not part 

of the original type series; 3) Friese used different color codes for type labels, but these were not used consistently 

and his conventions are frequently misinterpreted; 4) the dates on his preprinted determination labels 

are often incorrect as these often significantly predate the actual identification; 5) Friese labeled and sold to 

collections a number of “types” for unpublished manuscript names; this practice is especially confusing when

these names were subsequently validated by other authors using different material (e.g., Trigona geissleri 

Cockerell 1918). The present contribution will facilitate the location and citation of all names validly proposed 

by Friese, establish the current status of all his genus-group names and of his species-group names currently 

treated as valid species, and will highlight Friese’s contribution to taxonomic and biological research on 

world bees. 

Friese biography 

A number of papers have detailed the life of Friese (Friese 1937; Guglia 1969; Gusenleitner 1991; Duty 1997; 

Friedrich 1998; Unger 1999; Duty 2001; Sombke 2003; Hevers 2006), and biographies of other entomologists 

mentioned herein can be found in compendiums of entomologists (Carpenter 1945, 1953; Gilbert 1977). 

Friese was born May 4 th , 1860 in Friesenhaus (Figure 2), Kirchenstrasse 1, Schwerin (Mecklenburg-Vorpommern), 

Germany to the wealthy and talented organ builder family of Friedrich Ludwig Theodor Friese (1827– 

1896) and Maria, born Müller. Friese’s paternal line included generations of organ builders; both his grandfather 

Friedrich Matthias Theodor Friese (1792–1863) and great grandfather Jacob Friedrich Friese (1765– 

1833) were skilled organ craftsmen. During his school years, in 1876, Friese was introduced to natural sciences 

by Sigismund Brauns (1839–1913: Sombke 2003), an early entomologist in the Schwerin area. Friese’s 

enthusiasm for biology, led him on field trips with both Brauns and Friedrich Wilhelm Konow (1843–1908: 

Duty 2001), during which he studied and collected both insect and plants. Due to a severe and prolonged illness 

with conjunctivitis (“pinkeye”), Friese dropped out of the Schweriner Realgymnasium (a nine-year high 

school program) in 1878 and entered the family business of organ building. During 1880–1882, while working 

on organ constructions in Halle-Merseburg, Friese met the influential entomologists Ernst Ludwig 

Taschenberg (1818–1898) and Otto Schmiedeknecht (1847–1936). The latter, then working on his monograph 

of European bees (Schmiedeknecht 1882–1884, 1885–1886), was a particularly important mentor who fostered 

young Friese’s specialization on and passion for bees. He invited the then 23 year old Friese on a tenweek 

collecting trip to southern France and Spain, including the Balearic Islands in 1883. The large number of 

natural history specimens collected by Friese during this trip were sold, covering the cost of the trip and 

allowing Friese to arrange an extended stay in Paris, where he examined the insect collections of earlier entomologists 

such as Pierre André Latreille (1762–1833), Baron George Léopold Chrétien Frédéric Dagobert 

Cuvier (1769–1832), Amedée Louis Michel Lepeletier, Comte et Saint Fargeau (1770–1845), and Jules Sichel 

(1802–1868). Soon after returning to Austria, Friese embarked in 1884 on another lengthy trip to study the 

Swiss alpine flora and fauna in Geneva, Canton Jura, and the St. Gotthard Pass, at the invitation of Emile 

Frey-Gessner (1826–1917). Friese then went to Hungary, Siebenbürgen (now in Romania), and Dalmatia 

(now in Croatia), where he collected more than 10,000 bees chiefly from the distinctive pannonic steppes and 

grasslands, all accompanied with detailed observations on the biology of the wild bees and the flowers upon 

which they foraged (e.g., Friese 1886, 1887a, 1887b, 1937). 

In 1886 Friese again worked as organ builder in Paris and Strasbourg, where Alexander Wilhelm von 

Götte (1840–1922) encouraged Friese to matriculate in a three year graduate program in Zoology, Botany, and 

Physics at the University of Strasbourg. During his studies in Strasbourg (1886–1889), Friese collected bee 

nests and immature insects from surrounding areas and prepared them in glass vials for use in teaching collections. 

By selling these preparations to European institutions he earned enough to support his studies. By 1890 

the Friese family established an organ store in Oppenau (Baden-Württemberg), Germany, and when Friese’s 

share was sold a few years later, he gained economic independence and moved with his family to Siebererstrasse 

5, Innsbruck, Austria, where he commenced “Bienen Europa’s”, a scheduled eight volume monograph 

of the European bee fauna, of which six volumes were completed (Friese 1895, 1896, 1897, 1898a, 1899a, 

1901). In Innsbruck, Friese also met the influential hymenopterists Karl Wilhelm von Dalla Torre (1850–

1928), Anton Handlirsch (1865–1935), and Franz Friedrich Kohl (1851–1924), who assisted Friese in shaping 

ideas for his future works. Dalla Torre also coauthored many replacement names with Friese. Later, in 1900, 

Friese moved to Wagnerstrasse 28, Jena (Thüringen, in central Germany), where he began work on several of 

his most important monographs, including one treating the bees of Africa (Friese 1909c). Friese moved back 

to his birth house in northern Germany, Friesenhaus, in 1905 and soon after received a Honoris causa doctoral 

degree in philosophy on August 2 nd of 1907 from the nearby Justus-Liebig-Universität in Gießen. During 

World War I (1914–1918) Friese began biological research at the Schweriner Landesgesundheitsamt on 

wood-rot, rearing of silk-worms, malaria transmitting Anopheles mosquitoes in Mecklenburg, and the importance 

of hygiene in houses; a job he kept until retiring in 1931. From 1925 onward his official work also 

included studies of bee diseases. Friese suffered the post-WWI monetary depreciation and lost contact with 

many of the collectors who had supplied him with specimens from exotic places including but not limited to 

outposts of the formerly powerful German empire. By the age of 66, in 1926, Friese described new species at 

a reduced rate until 1939, when he published his last description of a new bee coincident with the outbreak of 

World War II in Europe. During the last years of life, Friese would often ride his bicycle through the countryside 

of Schwerin scouting for bees accompanied by young students who shared his entomological interests. 

Friese died in Kirchenstrasse on September 8 th , 1948, and his last biological papers appeared posthumously in 

1949 (Friese 1949b, 1949a), the same year that Cockerell’s last paper was published, also posthumously 

(Cockerell 1949). An era of describing world bees had ended.

Friese’s importance and contribution 

Between 1883 and 1939 Friese described 1,989 new species and 564 new varieties or subspecies of insects 

from around the world. Only two of these new species-group taxa and one new genus were wasps and one 

other taxon was a new variety of the bee beetle (Coleoptera, Scarabaeidae, Trichius fasciatus Linnaeus). The 

remaining taxa described by Friese were all bees, including 31 new genera and 37 new subgenera. He proposed 

73 replacement names for junior homonyms, of which 24 were coauthored by Dalla Torre. Inadvert-

ently he introduced 33 nomina nuda by reporting his manuscript species names, attributed to himself, without 

providing a description. He also, presumable inadvertently, repeated descriptions of new taxa 118 times. His 

interest was initially in the Palearctic fauna, but starting in 1898, he commenced publishing on exotic bees, 

eventually encompassing all biogeographic regions where bees are encountered, although he did relatively little 

work on the Nearctic fauna. Numerous new taxa were proposed in Megachile (262 taxa, including duplicate 

names), Bombus (232), and Halictus (153), but Friese was interested in all kinds of bees and described 

new taxa in 124 different bee genera, including all extant families: Apidae (1,257), Megachilidae (704), Halictidae 

(408), Colletidae (234), Andrenidae (208), Melittidae (37), and the small Australian endemic family 

Stenotritidae (1). His broad interest in describing exotic bee faunas is also reflected in the diversity of biogeographical 

regions covered, including the Neotropical (952 species-group taxa), Palearctic (711), Afrotropical 

(688), Australasian (193), especially New Guinea (Friese 1909a, 1909(“1908”), 1911c, 1911b, 1912b, 1915), 

Indo-Malay (114), and Nearctic (10) regions. The paucity of new taxa from the Nearctic region is likely due to 

the fact that he received less material from collectors and that contemporary bee students and correspondents 

of Friese residing in the United States were already working extensively with Nearctic bees, including Charles 

Robertson (1858–1935) and most notably T.D.A. Cockerell. The latter largely refrained from working on 

western Palearctic bees but complemented and competed with Friese’s work on the bee faunas of areas such 

as Australasia, Africa, and the Neotropics, a process resulting in many synonyms, many of which remain to be 

documented. Of the new bee taxa described by Friese, 77% included description of the female sex and 56% 

included description of the male sex. 

The strength of Friese’s publications include early attempts to synthesize taxonomic and biological information 

in a monographic or revisionary form, either of regional (e.g., Friese 1895, 1909c) or taxonomic (e.g., 

Friese 1901(“1900”)) character. In particular, he may also be considered one of the first authors to include 

detailed biological observations on a very broad range of bees, including presentation of the fascinating life of 

the bees to a wide audience in his well-illustrated and popular “Die europäischen Bienen” (Friese 1923). His 

descriptions are by modern standards inadequate, as is also the case of most of his contemporaries, and line 

drawings are generally absent, although his paper on Megachilinae (Friese 1911a) has a good number of illustrations 

for its time. Colored figures are found in few publications (e.g., Friese 1902, 1908, 1909c), and he 

occasionally included photographs of new taxa in later publications (e.g., Friese 1912a). 

Friese’s species concept was different from that of modern specialists, as exemplified by his treatment of 

the bumble bees, a notoriously variable group with the highest known levels of synonymies of any group of 

animals (Williams 1998). In an attempt to document all variation encountered, including color forms now 

regarded as trivial, Friese named 232 taxa of Bombus: 29 as new species and 152 as new varieties (the remaining 

were described a second time or proposed as replacement names). Nonetheless, only twelve Bombus 

named by Friese are recognized today as valid species (Williams 1998). Friese named local color forms as 

varieties or subspecies, his exact distinction remaining obscure, although he explained the difference as “… 

dass Local-Varietät und Subspecies nur zwei verschiedene Etappen auf dem Wege zu specifischer Formenbildung 

sind, zwei Entwicklungsstadien in dem Sinne, dass die Varietät einen jüngern, frühern, die Unterart 

einen ältern, spätern Zustand darstellt.” (“the local variety and subspecies are only two different phases on the 

way to creating a specific form; two developmental stages in the sense that a variety is the young and early 

phase and the subspecies the old and late phase”) (Friese & von Wagner 1904). This embracement of evolutionary 

theory was inspired by Friese’s studies of Charles Darwin’s writing, which began in high school 

(Friese 1937). According to the International Commission on Zoological Nomenclature (art. 45.6.4.) names 

proposed by Friese as a “variety” or “form” are deemed subspecific, as these were published before 1961 and 

there is no indication that Friese proposed the names as infrasubspecific entities (except only Bombus terrestris 

var. fulvocinctus comb. niveicollis Friese 1931). 

Most of Friese’s papers were single authored, although a few collaborative nomenclatural and review 

papers were coauthored with Dalla Torre while in Innsbruck (Dalla Torre & Friese 1894, 1895, 1899). Publi-

cations also included a series of comprehensive theoretical and taxonomic articles on bumble bees co-written 

with Franz von Wagner (Friese & von Wagner 1904, 1910, 1912, 1914), a friend from Friese’s student days in 

Strasbourg. Other joint publications had the individually authored sections well defined and separated 

(Jensen-Haarup 1908b, 1908a, 1908c; Schulthess & Friese 1914; Fahringer & Friese 1921; Schulthess 1924; 

Friese & Schulthess 1924(“1923”)). 

Friese types and depositories 

Friese donated his main personal collection to the Museum für Naturkunde (Berlin) in March 1916 (Guglia 

1969; Horn et al. 1990). Smaller collections, including type material, can be identified as having been deposited 

in subsequent lots in Berlin (Frank Koch, pers. comm.), Deutsches Entomologisches Institut im ZALF 

(Müncheberg; Holger H. Dathe and Stephan Blank, pers. comm.), Museum für Tierkunde (Dresden; Björn 

Rulik and Klaus Klass, pers. comm.), Naturmuseum Senckenberg (Frankfurt, Jens-Peter Kopelke, pers. 

comm.), Zoologische Sammlung der Universität Rostock (Sombke 2003), and an early collection of parasitic 

wasps in the Staatliches Naturhistorisches Museum Braunschweig (Hevers 2006). Furthermore, Friese visited 

and described collections of bees in the Magyar Természettudományi Múzeum (Hungarian Natural History 

Museum, Budapest, Sándor Csõsz, pers. comm.), Naturhistorisches Museum Wien (Michael Madl, pers. 

comm.), Zoologische Staatssammlung München (Klaus Schönitzer, pers. comm.), and perhaps others. The 

following collections also house material identified by Friese, often including putative or genuine type material: 

American Museum of Natural History (New York, pers. obs.), California Academy of Sciences (San 

Francisco, pers. obs.), Eidgenössische Technische Hochschule Zürich (Switzerland), Illinois Natural History 

Survey (Champaign, pers. obs.), Muséum d'Histoire Naturelle (Geneva, e.g., Friese & Schulthess 

1924(“1923”)), Muséum national d'Histoire naturelle (Paris, e.g., Friese 1901(“1900”)), Nationaal Natuurhistorisch 

Museum “Naturalis” (Leiden, e.g., Friese 1914), Natural History Museum (London, David Notton, 

pers. comm.), Naturhistoriska riksmuseet (Stockholm, e.g., Friese 1914), Smithsonian Institution, National 

Museum of Natural History (Washington, D.C., pers. obs.), Staatliches Museum für Naturkunde (Stuttgart, 

e.g., Friese 1909a), Wissenschaftsbereich Zoologie, Martin-Luther-Universität (Halle a.S, e.g., Friese 1912a), 

Zoological Museum (Copenhagen, pers. obs.), Zoologisch Museum, Universiteit van Amsterdam (Amsterdam, 

e.g., Friese 1918), Zoologisches Institut und Zoologisches Museum, Universität von Hamburg (e.g., 

Friese 1911b), and presumably Université de Strasbourg (Strasbourg) and Institut für Zoologie der Universität 

Innsbruck. 

Due initially to the reputation gained from the “Die Bienen Europa’s”, Friese received specimens from 

missionaries, travelers, professors, expatriates, colonists, or traders from all over the world, often with associated 

scholarly notes on floral records, nests, and other biological phenomena (e.g., Baker 2003). These private 

collections were identified and sometimes partially returned to the collectors. For example, part of the Jensen- 

Haarup collection of bees from Argentina is now deposited in the Zoological Museum in Copenhagen (pers. 

obs.). Friese also maintained a vivid correspondence and exchange with North American curators. In the 

Annual reports of the board of regents of the Smithsonian Institution (National Museum of Natural History, 

Washington, D.C.) from 1913, a purchase of 218 “Meliponidae” specimens (Apidae, Meliponini), incl. 90 

“cotypes” (syntypes), are listed in the inventory. Several other lots were received in exchange or through purchases 

the following years. The American Museum of Natural History (1921, 1924, and 1928; AMNH 

archives) and the Illinois Natural History Survey also purchased synoptic series of what were presumably 

long series of bees directly from Friese. For bumble bees (Bombus), the rates were $0.25 for workers, and 

$0.50 for males and queens (INHS archives). 

Friese rarely designated unique type specimens (holotypes) from his material, resulting in many syntype 

series. Due to the complex history of his scattered collection, even apparently unique Friese types in collec- 


RASMUSSEN & ASCHER

TERM OF USE 



tions should be regarded as syntypes, unless Friese explicitly states in the publication that only a single specimen 

was available to him, which he did for 158 holotype males and 238 holotype females. Friese’s practice of 

adding type labels to material he later received and identified as conspecific with previously described taxa 

must also be considered. Despite having a red or orange type (“Typus” or “Type”) label, specimens identified 

and labeled after the publication are not genuine types, and are sometimes not even conspecific with the indicated 

taxon (e.g., Michener 1965). It is therefore critical before selecting lectotypes to establish that the actual 

specimen corresponds well to the locality, collecting date, provenance, and description provided by Friese. 

Examples of Friese labels are provided in Figures 3–10, and Sombke (2003) illustrated additional label types. 

A brief survey for types in the Museum für Naturkunde in Berlin, revealed that six primary types of the nine 

Rhathymus taxa described by Friese were present in the collection; all of these six types corresponded to the 

original description, and all six were labeled with red type labels. Other apparent syntype series in the collection 

included a single specimen with a red type label and one or multiple specimens with orange type labels 

(e.g., Trigona frontalis, 1 red- and 4 orange-labeled type specimens; T. dutrae, 1 red and 4 orange; T. caerulea, 

1 red and 1 orange). While Friese’s color coding was inconsistent and sometimes misleading, we nonetheless 

suggest that revisors locate types with red labels when designating lectotypes as these were presumably 

intended by Friese as primary types or reference taxa, although syntypes with orange labels or lacking color 

coded labels are encountered and are equally available for lectotype designations under the International 

Commission on Zoological Nomenclature code. Most of the types sold by Friese to museums have orange 

labels and are tentative paratypes, paralectotypes, or are not genuine types at all when identified subsequent to 

the publication of the name. It is also important to note that neither red nor orange labels provide an infallible 

indication of genuine type material. For example three specimens of Trigona schrottkyi in the Museum für 

Naturkunde are labeled with one red and two orange type labels, although they were collected (1902) and presumably 

identified (1909) several years after the publication (1900) of this species and thus cannot even be 

considered part of the type series. Evidently material identified by Friese, including important and unique type 

material, has been scattered among numerous depositories, probably more than have been confirmed here. 

Most of Friese’s material in German collections is fortunately known to have survived WWII, so thorough 

searches for genuine, preferred (often red-labeled) syntypes in all known depositories are necessary before 

presuming these are lost and selecting alternative syntypes as lectotype. 

How the bibliography was compiled 

The bibliography was compiled by obtaining all Friese references listed in entomological bibliographies 

(Zoological Society of London 1864–present; Derksen & Scheiding-Göllner 1963; Guglia 1969; Scheele & 

Natalis 1981; Friedrich 1998; Pesenko & Astafurova 2003; Michener 2007). Subsequently, Friese reprint collections 

in the Museum für Naturkunde (Berlin) and Deutsches Entomologisches Institut im ZALF (Müncheberg) 

were searched for additional titles. Friese papers cited within these references were then traced until no 

further references were encountered. Publication dates were determined by the publishers imprint date on the 

wrapper of the fascicle, when available, or information contained within the issue. When the imprint year of 

the issue differed from the stated year of the volume, the latter are placed in parentheses. A number of separata 

(or reprints, but actually “pre-prints”) were issued in advance of the complete volume (or fascicle), although 

these may not necessarily comply with the requirement for publication under the code and are difficult to 

trace. We note that the following papers may have been issued a year earlier than the date used herein (Friese 

1909b, 1917(“1916”)), and have been cited with these earlier dates in important sources such as Moure et al. 

(2007). Further date discrepancies may arise.

label only indicates that Friese is the author and determiner of the species, but not that this is a new taxon. 6. Trigona flaviventris. 

Not a type (AMNH). Orange “Typus” label suggest a type, but specimen collected after the description of the 

species. 7. Megacilissa tomentosa. Syntype (ZMHB). Early orange Type label. 8. Callosphecodes ralunensis. Holotype 

(ZMHB). Alternative red framed Type label. Additional label indicate that this specimen was part of Friese’s personal 

collection. 9. Trigona mellipes. Probable syntype (ZMHB). No type label on this specimen, but locality, collection date, 

and specimen corresponds with the original publication. Determination label only indicates that Friese is the author and 

determiner of the species, but not that this is a new taxon. Additional label indicate that this specimen was part of Friese’s 

personal collection and is now deposited in ZMHB. 10. Trigona handlirschi. Probable holotype (ZMHB). Orange Typus 

label. T. handlirschi was described based on a single worker from “Brasilia” (here =Amazonas, Brasil, 1897), but determination 

label is from 909 (=1909). As this was the only specimen of this taxa encountered and because it is from the 

type locality and was colleted before the publication of the species, it is presumed the holotype, although the determination 

label does not provide evidence for this. We have seen other cases were putative types were labeled with determination 

labels dating after the publication of the taxa, and it is not unlikely that Friese would add these labels at later date. 

How to use the catalog 

The catalog is sorted by taxon name with the original spelling corrected to conform with valid spelling as 

ruled under the code (International Commission on Zoological Nomenclature 1999). Required corrections 

included the removal of all diacritic marks, hyphens, or ligature of the letters a and e (æ) (art. 27). A majority 

of the corrections result from the use of umlauts in German words. These were removed and the letter “e” 

inserted after the vowel (art. 32.5.2.). While the code explicitly suggests a differing treatment of Scandinavian 

letters not part of the Latin alphabet, e.g., to use mjobergi for mjøbergi (based on a Swedish name), Friese 

used German umlauts in bee names derived from Scandinavian names (e.g., Anthidium jörgenseni for a bee 

named in honor of Jørgensen). We have therefore consistently treated all German forms of Scandinavian 

names as German words, as the Code requires in doubtful cases (e.g., A. joergenseni; art. 32.5.2.1.). We have 

removed the dieresis over the “e” in Anthidium morëense and in other names where it occurs and replaced 

numerals with written Latin words for numbers. Osmia moscaryi is considered one of several demonstrable

printer’s errors (art. 32.5.1.), as the specific epithet refers to Sándor (Alexander) Mocsáry (1841–1915). This 

name is therefore cited as Osmia mocsaryi, following precedent (e.g., Scheuchl 2006). 

After the corrected taxon names we list the precise original spelling in brackets, when differing from the 

corrected, currently valid spelling, and then the original genus (Table 1) and subgenus (Table 2). In some 

cases the original genus of a Friese species-group taxon is not entirely clear, as he sometimes referred to a 

genus-group taxon as a subgenus in the text, classificatory table, and/or key, but cited it as if it were a genus in 

the heading above the description. For example, Epicharis is treated as a subgenus in the introduction, keys, 

and classificatory table of his monograph of Centris s.l. (Friese 1901(“1900”), p. 241, 244, a.o.). However, 

when describing new taxa he cited the combination in the heading above the description with Epicharis as the 

only indicated genus-group name (i.e., Epicharis umbraculata var. nigrita), as if Epicharis were the original 

genus, instead of making the status of Epicharis as a subgenus of Centris explicit (i.e., Centris (Epicharis) 

umbraculata var. nigrita), as in the classificatory table and keys. The importance of this distinction is that 

when citing the authority of the taxa, parentheses are placed around the authority to reflect a modified generic 

combination. In this case, the taxa in question are now placed in genus Epicharis, so parentheses should be 

added if the original genus is considered to be Centris, but omitted if the original genus is considered to be 

Epicharis. In this catalog we have attempted to locate unambiguous and even implicit statements of Friese’s 

intentions through study of all relevant text and tables and have not assumed that a genus-group name cited in 

a species heading refer to a genus (i.e., it could refer to a subgenus). This interpretation conflicts with that of 

some previous authorities, including Michener (2007). We believe it is best to attempt to follow the explicitly 

stated intention of the author with respect to the rank of taxa, including generic versus subgeneric rank of 

genus-group names in species headings, but recognize that there is room for interpretation in certain ambiguous 

cases. 

Following the original genus-group names are a species name in the case of a new subspecies or taxon 

deemed subspecific, authority and reference, page numbers in the reference, taxonomic code (s, species; ss, 

subspecies and also varieties and forms deemed subspecific; nom. nov., nomen novum, a replacement name 

proposed for a junior homonym; nom. nud., nomen nudum, a published name without validity due to lack of 

accompanying description; n genus, new genus; n subgenus, new subgenus), sex, and number of original type 

specimens when stated. 

Friese would occasionally only indicate that the series consisted of males or females, but not if they were 

represented by multiple specimens. Therefore % or & may represent any number of typical specimens (i.e., 

syntypes). This is followed by biogeographical region (AT, Afrotropical; AA, Australasia; IM, Indo-Malay; 

NE, Nearctic; NT, Neotropical; PA, Palearctic), currently valid name for Friese taxa now regarded as valid 

species, the family to which the taxon belongs, and lastly taxonomic comments. For all genus-group names 

the current status is indicated, whether valid or a synonym, and annotated as appropriate (e.g., certain cases 

where recent authors differ in their interpretations). 

All Friese species-group names currently regarded as valid species are cited in their currently accepted 

combinations with subgeneric placements indicated where appropriate and available based on references 

listed in Michener (2007) and subsequent publications (Camargo and Pedro 2007; Moure et al. 2007; Raw 

2007) and, in some cases, unpublished information available to the authors (Ascher et al. 2008). Friese species-group 

taxa regarded by us as nominally valid subspecies or varieties, as synonyms, or for which we have 

no reliable information are not treated herein pending further studies as part of the World Bee Catalog Project 

and the Bee Barcoding of Life project (BEE-BOL; www.yorku.ca/bugsrus), which will entail comprehensive 

review and documentation of all bee names and a reassessment of their validity and rank. Note that we do not 

follow Moure et al. (2007) in newly recognizing valid subspecies as species, awaiting further support for recognizing 

these taxa previously regarded as infraspecific.

Friese sometimes described taxa multiple times. When he provided the literature reference to the original 

description in any subsequent supposedly new description, we do not consider it a new description and these 

are not listed in the catalog, even in cases where Friese noted “n.sp.” or “n.var.” following the name. However, 

if no such reference is made to previous publications, the taxon has been included, but an asterisk (*) has been 

placed before the taxonomy code to indicate its status as an apparent duplicate description. These redescriptions 

are not valid proposals of a new taxon, even though some use a slightly different spelling, but are 

included in the catalog for sake of completeness. 

Friese also left very numerous specimens labeled with manuscript names in collections. These manuscript 

names are not included in this catalog, unless Friese made reference in the literature to these taxa himself 

without providing a description, in which case they are cited as nomina nuda. Such manuscript names have 

complicated revisions and checklists as it has been difficult, in the absence of a complete list of validly proposed 

Friese names, to establish that a name was never published (e.g., Pauly 1990). An important contribution 

of the present catalog is that it will provide a secure basis for establishing whether or not a name was ever 

published by Friese. 

We list here all taxa validated by Friese, including manuscript names of colleagues (e.g., Allodape friesei 

Brauns in litt.) validated by providing the name and a description (e.g., Allodape friesei Friese 1924). We do 

not list taxa described by colleagues in Friese’s publications, including those proposed by Hans Heinrich Justus 

Carl Ernst Brauns (1857–1929, in Friese 1905), Sándor Mocsáry (in Friese 1898b, 1899b), and Anton von 

Schulthess (1855–1941, in Schulthess 1924).
