8 Gastromyzontidae Fowler, 1905
Gastromyzoninae Fowler, 1905: 477 (type genus: Gastromyzon
Günther, 1874: 454; correct stem is Gastromyzont–
and correct spelling is Gastromyzontinae)
Lepidoglanidae Jordan, 1923: 149 (type genus: Lepidoglanis
Vaillant, 1890: 82; correct stem is Lepidoglanid– and
correct spelling is Lepidoglanididae)
Crossostominae Silas, 1953: 219 (type genus: Crossostoma
Sauvage, 1878a: 88; invalid because of junior homonymy
of type genus, Code art. 39; correct stem is Crossostomat–
and correct spelling is Crossostomatinae)
Glaniopsini Silas, 1953: 259 (type genus: Glaniopsis Boulenger,
1899a: 228)
Pseudogastromyzoni Silas, 1953: 299 (type genus Pseudogastromyzon
Nichols, 1925e: 1; correct stem is Pseudogastromyzont–
and correct spelling is Pseudogastromyzontini)
Beaufortini Chen, 1980b: 207 (type genus: Beaufortia Hora,
1932a: 318; correct stem is Beauforti– and the correct
spelling is Beaufortiini)
Parhomalopterini Chen, 1980b: 207 (type genus: Parhomaloptera
Vaillant, 1902: 129)
Taxonomic notes. Authors have recognised and named various
subdivisions within Gastromyzontidae. For example,
Silas (1953: 219) recognised two subfamilies: Gastromyzontinae
and Crossostomatinae. Chen (1980b: 207)
recognised four tribes ("groups"): Parhomalopterini, Crossostomatini,
Beaufortiini and Gastromyzontini. Gastromyzontini
(the genera from Borneo) probably corresponds
to a monophyletic lineage. Crossostomatini and
Beaufortiini too, possibly correspond to monophyletic lineages.
Parhomalopterini, with one genus in Borneo and the
remaining ones in mainland Southeast Asia, is apparently
an heterogeneous assemblage. It seems premature to recognise
subfamilies or other divisions within Gastromyzontidae.

Annamia Hora, 1932a: 306 (type species: Parhomaloptera
normani Hora, 1930: 584, by original designation). Gender

Species inquirenda
Annamia thuathienensis Nguyen [H. D.] & Nguyen [V. H.],

san drainage, Mekong basin]; holotype: BMNH
1930.5.5.1, Eschmeyer & Fricke, 2010; noun in genitive,
indeclinable)
8.2 Beaufortia Hora, 1932
Beaufortia Hora, 1932: 318 (type species: Gastromyzon leveretti
Nichols & Pope, 1927: 340, by original designation).
Gender feminine.
Taxonomic notes. The validitidy of the many names created
in recent years in the Vietnamese literature cannot be evaluated.
The descriptions are of little use and the quality of the
illustrations of most species does not allow to guess their
identity. As most species have very restricted ranges, it is
expected that those from widely distant localities might in
fact be valid, while the many species described from exactly
the same locality may be found to represent single species.
For some species, however, there is not even informative
locality data.
8.2.1 ? Beaufortia buas (Mai, 1978)
Gastromyzon buas Mai, 1978: 215, fig. 99 (type locality:
northern Vietnam [Bua River, Song La and Phu Tho provinces;
Kottelat, 2001a: 98]; syntypes: DVZUT; treated
as noun in apposition, indeclinable)
8.2.2 Beaufortia cyclica Chen, 1980
Beaufortia cyclica Chen, 1980a: 115, fig. 6 (type locality:
China: Guangxi: West River in Longzhow Xian; holotype:
IHB 75IV1417; adjective, -us, -a, -um)
Beaufortia polliciformis Dai, in Zheng, 1981: 172, fig. 142
(type locality: China: Guangxi: Longzhou County: Dong
Gui River; holotype: ASIZB 751842; adjective, -is, -is, -e)
Taxonomic notes. Possibly a junior synonym of B. elongata.
8.2.3 Beaufortia daon (Mai, 1978)
Gastromyzon daon Mai, 1978: 216, fig. 100 (type locality:
Vietnam: Lai Chau Province: Phong Tho and Nam Na
streams [Song Da drainage]; syntypes: DVZUT; treated
as noun in apposition, indeclinable)
8.2.4 Beaufortia elongata (Mai, 1978)
Gastromyzon elongatus Mai, 1978: 213, fig. 98 (type locality:
northern Vietnam; syntypes: DVZUT; adjective, -us,
-a, -um)
Taxonomic notes. No usable locality information. Apparently
close to or a senior synonym of B. cyclica, known from
the Pearl River drainage in Guangxi, China. Nguyen (2005:
284) identified as B. elongata material from the Song Con
River in Thai Nguyen Province, in the Red River drainage.
The identity of this species and its range remain to be determined.
