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.

This species is available sporadically and makes an excellent choice for those new to keeping loaches. It’s distinguishable from congeners by a combination of characters including: truncate/rounded caudal-fin; no scales on top of head; dark, squarish spots o…

The distribution records for this species are somewhat confusing. It was described from the confluence of the Lamatang and Enim rivers, Palambang Province, Sumatra and has since been recorded from Thailand (Chao Phraya River), Peninsular Malaysia (Pahang River) plus the islands of Java (Solo River) and Borneo (Kapuas and Barito rivers).

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…

The genus Kottelatlimia was erected by Nalbant (1994) to accommodate K. katik which had previously been assigned to Lepidocephalichthys but differs in various aspects noted earlier by Kottelat and Lim (1992) including: relatively small adult size; scaleless…

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.

The family Cobitidae, often referred to as ‘true’ loaches, is widely-distributed across most of Eurasia with the Indian subcontinent, Southeast Asia and China representing particular centres of species diversity.

Type locality is given as ‘Kuala Tahan, Pahang (King George V National Park)’ which corresponds to the village of Kuala Tahan in Pahang state, central Peninsular Malaysia.

The settlement is located at the confluence of the Tahan and Tembiling Rivers which form part of the Pahang river basin, while the national park was re…

At time of writing there exist 18 recognised members of the genus though only B. kweichowensis is well-known in the trade with B. szechuanensis unlikely to have been exported. According to Chen, Huang and Yang (2009) it can be distinguished from similar congeners by the following suite of characters: 1 branched and 17-20 simple pectoral-fin rays…

Erromyzon spp. are obligate dwellers of shallow, fast-flowing, highly-oxygenated headwaters/minor tributaries characterised by stretches of riffles and runs broken up by pools or cascades in some cases. Substrates are normally composed of smaller rocks, sand and gravel with jumbles of boulders, and while riparian/stream-side vegetation and patches of submerged leaf litter are common features aquatic plants aren’t usually present.
