In a study conducted on the Arataye River, the main tributary of the Approuage, this species was mostly collected from stretches of rapids with rocky substrate which were reduced to a series of pools during the dry season. Other fishes observed at the same site were Auchenipterus nuchalis, Hypostomus gymnorhynchus and Moenkhausia cf. intermedia while at other localities in the river Bryconops affinis, Myleus ternetzi, M. rhomboidalis, Moenkhausia aff. barbouri, Curimata sp. and Serrasalmus sp. were collected.

G. ornatapinnis can be distinguished from congeners by the following combination of characters: head small; snout relatively short and blunt; caudal peduncle very deep; pectoral, pelvic, and anal fins usually reddish-orange or rose-tinted; pelvic and anal fins often with white tips; barbels completely absent.

The genus Homalopteroides was revalidated by Randall and Page (2012) and is told apart from the related Homaloptera by the following character combination: dorsal-fin origin above pelvic-fin; ≤ 60 lateral-line scales; ≤ 30 predorsal scales; oral morphology consisting of two thin and widely separated rostral barbels on each side of the mouth, thin crescent-shaped lips, the absence of any structure such as a mental pad or lobes between the lateral portions of the lower lip, and a chin that extends anterior to the lateral portions of the lower lip.

Tan (2009) redescribed H. stephensoni and it possesses the following unique character set: sub-inferior mouth with thin barbels; five principle, 12-13 secondary pectoral fin rays (usually 12); scaleless belly; pattern of keeled scales on anterior, dorsal portion of body consisting of a single central keel in the posterior third of each scale; 43-50 lateral line...

The genus is monotypic and distinguished from other cyprinid taxa by a combination of a moderately compressed, elongated body with two rows of teeth on the lower pharyngeal (throat) bone and lacking barbles, visible lateral line and a symphyseal knob on the lower jaw (Talwar & Jhingran, 1991). Its small adult size evolved via a process known as miniaturisation characterised by sexually mature adults with a significantly reduced size of less than 20 mm SL. Among bony fishes cyprinids are one of the few groups in which this phenomenon occurs repeatedly...

There are currently eleven species in the genus most of which have previously been included in Puntius, Barbus and the now defunct genus Gonoproktopterus. Of these the only ones we've seen in the trade are H. jerdoni and H. curmuca although it's possible that others have been exported in small numbers or as contaminants among shipments of other species. Even these two are very rarely encountered and little has been written about the group as a whole....

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...

It's most easily told apart from K. brevifasciata, its only congener, by body patterning consisting of dark, vertical bars running along the dorso-ventral part of the body (vs. dark bars running alongside the midventral part of the body), lips with wrinkled surfaces (vs. smooth) and barbels short (vs. long).

This species differs from congeners in the presence of papillae covering the mouthparts (lips, barbels, and lobes) which are absent in other species. It's also the largest species in the genus and the serrae on the second pectoral fin rays in males form a broa...

We're unaware of this species having yet appeared in the aquarium trade although a few private collectors have experience with it. Among congeners it uniquely possesses a simple suborbital spine and further differs from K. pristes by: smaller adult size (13.5 mm SL vs. 40); presence of a long nasal barbel (vs. absence); anatomy of the modified second pectoral ray in males (6-7 fine, narrow serrae vs. 8-11 pointed, anteriorly-orientated serrae). In K. hipporhynchos the serrae on the second pectoral ray in males form a broad, contiguous blade-like structure but other differences are the same as for K. pristes.

This species is likely to be traded for aquaria but probably misidentified as the very similar-looking K. cyrptopterus with which wild populations were formerly considered conspecific. These two are closely-related and can be distinguished from congeners by the dorsal profile lacking a nuchal concavity (vs. possessing a nuchal concavity) and possessing short maxillary barbels (extending to the pectoral-fin base vs. ext...

This species is also known as 'leaping barb' and was once quite common in the ornamental trade but is now seldom seen. It can be distinguished from other members of the genus by the following characters: bright blue spot on top of head; series of 4-5 short faint bars on anterior portion of body; 19-23½ branched anal-fin rays; body depth fits 2.1-2.9 times in SL.

L. disparis is sometimes available as bycatch among shipments of other species such as Rhinogobius duospilus but also appears on trade lists under the fictitious scientific name 'Homaloptera hoffmani'. It can be told apart from similar-looking members of the genus Formosania by its noticeably shorter barbels and from Vanmanenia spp. by the fact that the rostral fold is not lobed and the mouth is relatively small (25% head width. In addition the lower lip in Liniparhomaloptera is not divided and has a flat, papillated edge.

The genus Microdevario was raised by Fang et al. (2009) after phylogenetic analyses revealed that some species formerly included in Microrasbora to be more closely allied with Devario and in need of reclassification. Microdevario is largely separated from Devario and other closely related genera such as Chela and Laubuca by virtue of internal characters but also the following: small adult size; anal and dorsal fins with concave-shaped distal margin; absence of barbels; absence of perforated scales; 9-10 branched anal-fin rays; 7 branched dorsal-fin rays; less abdominal than caudal vertebrae.

This species can be distinguished from congeners by the following combination of characters: body depth fits 2.5-2.7 times in SL; 28-31 +2-3 lateral line scales; 14-16 circumpeduncular scale rows; 5-5½ scale rows between the lateral line and dorsal-fin origin; a triangular distal blotch on the dorsal-fin; a few body scales with crescent-shaped black edges; a thin dark margin on the dorsal-fin, posterior to the distal blotch; a dark posterior margin on the caudal-fin; normally a single pair of rudimentary barbels present.

This species can be distinguished from congeners by the following combination of characters: body relatively slender, depth fitting 3.4-3.8 times in SL; 32-33 + 2 lateral line scales; 14 circumpeduncular scale rows; presence of a single pair of barbels; black distal margin on dorsal-fin; numerous body scales with dark, crescent-shaped markings.

N. alestes is the only member of the genus in which the barbels are shorter than the head, with additional diagnostic characters as follows: 8-9 branched dorsal-fin rays; 12-14 branched anal-fin rays; 22-23 predorsal scales; body with a pronounced ventral keel.
