Prior to description this species was traded under the DATZ code L239. It can be distinguished from other species in the genus and other hypostomines (see below for definition of this grouping) by its uniformly black to brownish body and fin colouration with a turquoise to bluish sheen, and the acutely bent shape of midventral body plates 3-5 which form a distinctive keel running along the body, above the pectoral fins...

Prior to description this species was traded under the DATZ code L047 or the alternative vernacular name 'magnum pleco'. It can be distinguished from congeners by a combination of the following characters: presence of a broad, light-coloured (usually yellowish) distal band on the dorsal and caudal fins throughout life, slightly reduced in adults. The only other member of the genus to possess such bands is B. xanthellus but in that species they are reduced to small markings at the fin tips in adults, and the body is covered in pale, normally yellowish, spots.

It remains unconfirmed as to whether this fish represents a colour form of B. xanthellus or not since its DATZ code number of L081 is not referred to in the description paper whereas all other codes for 'gold nugget' plecos, i.e., L018, L085, L177 plus the 'Das Aquarium' code LDA060 are mentioned. In addition, one of the specimens in our images was apparently collected at São Félix do Xingu which is significantl...

This species is available in the aquarium hobby but is not traded in large numbers and may have been inadvertently hybridised with the similar-looking congener B. rubra prior to its description since they're typically exported mixed together. It's included in the B. rubra group of closely-related species within the genus, an assemblage erected by Schindler and van der Voort (2012) who...

This species is often confused with B. krataios in the aquarium trade, the latter having been known as B. sp. 'Kapuas' prior to description. The two can easily be told apart as the caudal-fin is rounded in B. krataios but spade-shaped and in adults, highly-extended in B. dimidiata. Together these two comprise the B. dimidiata group of closely-related species within the gen...

Prior to official description this species was traded as B. sp. 'Laut'. It's included in the Betta unimaculata complex of closely-related species within the genus, , of which members share the following set of characters: body long and slender with depth at dorsal fin origin 18-25 % SL; head large and blunt with width 19-24 % SL; long maxilla and lower lip with distance from tip of lower jaw to posterior end of maxilla 27-54 % HL; caudal-fin rounded in sha...

This species was traded as B. sp. 'Kapuas' prior to its formal description and continues to be mislabelled B. dimidiata. The two can easily be told apart as the caudal-fin is rounded in B. krataios but spade-shaped and in adults, highly-extended in B. dimidiata. Together these two comprise the B. dimidiata group/complex of closely-related species within the genus, members of which can be characterised b...

This species was known as B. sp. 'Mandor' or B. sp. 'ninja' prior to official description. It belongs to the Betta foerschi group/complex of closely-related species within the genus, of which members share the following set of characters: possession of iridescent blue or green unpaired fins; rays and interradial membranes in unpaired fins not contrasting; dorsal fin with thin, bright white distal band; opercle with two, reddish-yellow, vertical bars. Members are regarded as being closely-related to bubble-nesting Betta species since they share exhibit certain similarities in morp...

This species was considered a colour form of the closely-related B. imbellis and commonly-referred to as 'black imbellis' prior to description due to its blackish opercle and body. It's also previously been confused with B. splendens due to the colour of the vertical opercular bars which tend to be reddish (but may also be pale red, greenish-silvery, plain silvery or without colour in some populations), but DNA analysis has demonstrated it...

Known only from southern (peninsular) Thailand with the type series originating from a swamp some 83 km north of Surat Thani city, Surat Thani province. It's been recorded at additional locations, all within the lower Tapi river drainage on the Gulf of Thailand slope of the Malay Peninsula. In the description Conway and Kottelat (2011) report the occurence of a similar-looking, possibly conspecific fish on the Andaman Sea side of the Peninsula, close to Trang province.

To date known only from the Jaintia Hills district, Meghalaya state, northeastern India meaning its natural waters are part of the Brahmaputra River system. The type locality is given as 'Tre Rangriang, Jowai' in the description paper, but we've been unable to locate this on any map. The paratypes were collected at 'Thlu Muwi', which probably refers to the ancient stone bridge built over the Muwi stream, a place popular with tourists due to the nearby Muwi waterfalls.

Adult size is comparable to B. nigrofasciata, and in the description paper the authors hypothesise that the two are closely-related given they share other features such as similar barbel length (plus some additional merisitic counts), absent lateral line and spotted pelvic fins. The two are easy to tell apart, however, since in B. tinwini the P+1 stripe is composed of a series of spots (vs. solid), it possesses an indistinct P+2 str...

This species was available in the aquarium hobby for a number of years prior to description and continues to be traded under various names including C. sp. 'Lal Cheng', C. sp. 'Assam', C. sp. 'blue bleheri', C. sp. 'himalayanus', and C. sp. 'red'. The names of valid, but distinct, congeners such as C. amphibeus, C. bleheri or C. stewartii have also been misapplied to it.

This species was present in the hobby for some time prior to being officially described and the spectacular red fish first exported by Pierre Brichard in the 1960s appears to be a regional form of it. It was also known variously as Nanochromis sp. 'Bamanja', N. sp. 'Genema', N. sp. 'Makoua' and N. sp. Bloody Mary' prior to description, and continues to be mislabelled as N. squamiceps on trade lists. Diagnosis of C. sabinae is possible via a combination of c...

This species has been widely referred to as the congener C. nattereri in aquarium literature both prior to and post-publication of its official description in 2006. The two can be told apart quite easily by the fact that C. nattereri possesses a dark lateral stripe while C. meinkeni does not. C. meinkeni can be distinguished from all congeners by the followi...

Type locality is 'Furo do Lago São Francisco, 7°40'S, 72°39'W, tributary at left bank of Rio Juruá, Acre State, Brazil', and C. acrensis appears to be endemic to the rio Juruá basin. Unfortunately diagnostic characters cannot be provided since we've been unable to obtain the type description, and little has been written about this species since it was published.

This species' name is commonly misapplied to a number of similar-looking fishes and it can be difficult to identify if collection locality is unknown. In addition, colour pattern is variable and it's not clear whether this occurs between, within, or both between and within populations. In the original description, Steindachner did note that the first three dorsal-fin rays are completely black while the remainder is whi...

C. amandajanea is rare in the aquarium trade and appears to be variable in colour pattern to an extent, with some individuals posssessing relatively larger dark spots on the body, for example. Unfortunately diagnostic characters cannot be provided since we've been unable to obtain the type description, and little has been written about this species since it was published.

This species is not well known and rarely traded for the aquarium hobby. Unfortunately diagnostic characters cannot be provided since we’ve been unable to obtain the type description, and little has been written about this species since it was published. It looks very similar to several congeners, particularly C. acrensis and C. cruziensis.

This species is not well-documented but is said to differ from the comparable C. punctatus by possessing larger dark markings on the body which may form an irregular midlateral stripe in some specimens. Unfortunately diagnostic characters cannot be provided since we’ve been unable to obtain the type description, and little has been written about the species since it was published.
