It is currently the only valid member of the genus but it is possible that additional taxa exist, particularly in Myanmar, while a number of former species are contained within the Laubuka assemblage, to which C. cachius is closely related. Phylogenetic studies suggest the existence of a monophyletic clade consisting of the genera Devario, Chela, Laubuca, Microdevario and Microrasbora plus the genus Betadevario.

The genus Amblypharyngodon currently contains five valid species, and A. chulabhornae can be distinguished from congeners by the following combination of characters: 42-50 (vs. 50-79) scales in the lateral row; lateral line incomplete with 6-7 (vs. 7-23) perforated scales; 4-5 scales on a transverse row between the lateral line and pelvic-fin base. All members of the genus lack barbels.

This unidentified species has only appeared in the aquarium trade on a handful of occasions and it has been widely misidentified as Devario jayarami (Barman, 1984).

It differs from D. jayarami by possessing 9-10 lateral bars which progressively increase in size posteriorly (vs. 12-13 bars which decrease in size posteriorly), 12 anal-fin rays (vs. 15-16) and a blunter head profile with a lack of convexity behind the head (vs. head profile conical with noticeable convexity behind the head).

This unidentified species was first collected in 2007 but very little is known about it.

The vernacular name refers to the colour pattern on the body which resembles that of a giraffe, and it’s known to be collected in Myanmar although its distribution and natural habitat remain a mystery.

Thrives in an aquarium set up to resemble a flowing stream or river with a substrate of variably-sized, water-worn rocks, sand, fine gravel and perhaps some small boulders.

This can be further furnished with driftwood roots or branches, and while the majority of aquatic plants will fail to thrive in such surroundings hardy types such as Microsorum, Bolbitis or Anubias spp. can be grown attached to the décor.

This species is sometimes referred to as ‘Hora danio’ or Salween danio’.

It is distinguished from similar-looking species by a combination of characters as follows: lateral line complete or incomplete with 22-33 pored scales; absence of infraorbital process; 7 branched dorsal-fin rays; usually 10 or 11 branched anal-fin rays; barbels absent or rudimentary; flank markings comprising a series of narrow vertical bars on the anterior portion of each flank, fol…

Appears endemic to tributaries of the Bhavani river system in the Nilgiri Hills of Tamil Nadu state, southern India including the Pykara, Avalanche and Kaity streams.

Type locality is ‘Ootacamund Lake, Pykara, Avelanche and Kaity streams, Neilgherry Hills, India’, with the former now often shortened to Ooty Lake.

Type locality is ‘Streamlets near Tangla, Darrang District, Assam, India’, but records also exist from the Mahananda River in West Bengal state and other tributaries of the lower Brahmaputra river system, some of which originate in Bhutan.

Further upstream it’s been recorded in the Kalmoni riv…

Type locality is ‘Tenasserim, Myanmar’ which at time of description was used to refer to the portion of Myanmar lying to the south and east of the Ayeyarwaddy/Irrawaddy river delta, including present-day Kayah, Kayin, and Mon states, Bago Division, and possibly the southern Tanintharyi Region.

Blyth’s description paper covered fishes collected from the Sittaung River (plus a few Gangetic species) in what is currently Bago Division, but we’ve been unable to locate any modern records of D. affinis fro…

Type locality is given as ‘Jiucheng, Yunnan Province, China’ which could refer to one of several places with the same name in southwestern Yunnan.

It’s also been collected in Tengchong and Lianghe districts, Yingjiang county, and all known localities are within the Daying river (Dayingjiang) watershed, a major tributary of the larger Irrawaddy/Ayeyarwady river syst…
