thick, triangular in cross-section, with distal wings; inserted almost medio-dorsally, covering the base of up to
3–4 dorsal radioles; constriction absent. Pseudoperculum absent. Radioles arranged almost in spirals (1.25
whorl), up to 42 per lobe. Stylodes and branchial eyes absent. Inter-radiolar membrane present. Mouth palps
absent. 7 thoracic chaetigerous segments. Collar trilobed, collar edge entire, smooth, occasionally with frilly
edge (G. hystrix). Tonguelets absent. Thoracic membranes forming apron. Collar chaetae small, limbate (Fig.
21A). Apomatus chaetae absent. Thoracic uncini saw-shaped with 7–10 teeth, anterior peg stout, rounded to
spatulate (Fig. 21C). Triangular depression absent. Abdominal chaetae true trumpet-shaped, smoothly bent,
with two rows of denticles separated by a hollow groove and extended into a long lateral spine (Fig. 21E).
Abdominal uncini with 11–15 teeth, anterior peg stout, rounded (Fig. 21D), posterior ones rasp-shaped with
2–3 rows. Long posterior capillary chaetae absent. Achaetous anterior abdominal zone short (2–3 segments).
Posterior glandular pad absent.
Remarks. The genus Galeolaria is one of the taxa that has been attributed to Savigny by various authors
(e.g., Fauchald 1977: 144). The Code, however, is very clear on the point of priority of publication, Lamarck
(1818) precedes Savigny (1820), and is the author of Galeolaria (cf. Fauchald 1992: 2–3).
The genus Galeolaria is endemic to the southern half of Australia and New Zealand. G. caespitosa is
gregarious and intertidal, whereas G. hystrix is solitary and subtidal, rarely forming “reefs” (see Smith et al.
2005). The uncorroborated records of Galeolaria caespitosa from New Caledonia by Fauvel (1947) and of G.
hystrix from N.W. Spain by Alvariño (1951) are most probably erroneous.

Type-species: Hyalopomatus claparedii Marenzeller, 1878
Number of species: 11 or 12
Tube white, opaque, sometimes with external hyaline layer, but granular overlay absent; (semi) circular in
cross-section. Tabulae may be present. Operculum globular, soft, without distinct endplate or consisting of
proximal ampulla with slightly chitinized distal cap; well separated from peduncle by constriction; sometimes
operculum absent. Peduncle very thin, cylindrical, smooth, without wings; inserted outside branchial crown
proper in front of first dorsal radiole on one side. However, for H. langerhansi we observed “between base of
first and second radiole”. Pseudoperculum absent. Arrangement of radioles short pectinate, up to 15 pairs of
radioles. Inter-radiolar membrane absent. Branchial eyes rarely present. Stylodes absent. Mouth palps present.
6 thoracic chaetigerous segments. Collar trilobed, tonguelets absent. Thoracic membranes short, ending at
first or second thoracic chaetiger. Collar chaetae fin-and-blade (Fig. 22A), or without gap between fin and
blade and thus with uniform distal denticulate wing, and limbate. Apomatus chaetae absent (contrary to Ben-
Eliahu & ten Hove 1989). Thoracic uncini rasp-shaped with numerous small teeth, approximately 20 in
profile, up to 9 teeth in a row above peg; anterior peg made of two rounded lobes with a shallow incision in
between, flat or slightly gouged in the middle (Fig. 22B). Triangular depression absent. Abdominal chaetae
almost capillary with only tip flat narrow geniculate with pointed teeth (Fig. 22D); uncini rasp-shaped, similar
to thoracic ones, but their anterior peg with 3–4 flat rounded lobes (Fig. 22C). Achaetous anterior abdominal
zone may be present. Posterior capillary chaetae present. Posterior glandular pad absent.
Remarks. This genus is poorly known probably because it includes mainly bathyal and abyssal species.
Zibrowius (1969a) revised the genus to include six species. Kupriyanova (1993c) described three new species
and provided a key to all species known at that time. More recently, three new species were added to the
genus, H. variorugosus Ben-Eliahu & Fiege (1996), who also discuss the then known species, the non-
