This species is probably the most common member of the genus in the aquarium trade but still not often exported in numbers.

Instead it’s more often found in mixed shipments of other wild-collected fishes from southern China, particularly Beaufortia or Pseudogastromyzon spp.

It may appear superficially simi…

This species is a relatively recent addition to the hobby but considering the number of specimens allowed to be collected for scientific research is highly restricted by the Taiwanese Council for Agriculture it seems odd that it's become available at all. Indeed it appears that those in the trade are collected and exported on an illegal basis (T-Y Liao, pers. comm.)…

We’re unsure if this species has ever been traded on a commercial basis though we know of several private collectors who’ve maintained it. It’s difficult to confuse with any other balitorid due to the small adult size and distinctive orange to reddish-brown body colouration, and was originally described as a subgenus by Herre (1944) before Silas (1953) raised it to full genus status. It was later syonymised with Homaloptera by Alfred (1969) but has been generally accepted as a distinct, valid genus since Roberts (1989).

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…

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…

An obligate dweller of swiftly-flowing streams and headwaters containing clear, oxygen-saturated water. It often inhabits riffles and runs and is likely to show a preference for shallower zones. Substrates are generally composed of gravel, rocks, boulders or bedrock carpeted with a rich biofilm formed by algae and other micro-organisms.

Juveniles are often found in slower-moving stretches with gravel substrate and submerged tree roots. In both cases patches of aquatic plants are only occasionally pres…

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.

Described from Kota Tinggi district, Johor state, Peninsular Malaysia but since recorded throughout much of the country as well as parts of the the Mekong river system in Thailand, Laos, Cambodia and Vietnam plus the Kapuas and several other river basins in Kalimantan Barat (West Kalimantan) province, Indonesian Borneo.

In the Kahang River, part of the Endau drainage in Jo…

Described from close to the village of Ban Khiri Wong, Nakhon Si Thammarat Province, southern (peninsular) Thailand but since recorded throughout much of the country, including the Chao Phraya and Mekong river systems.

It’s also known from Peninsular Malaysia and parts of the Mekong basin in Laos, Cambodia and Vietnam. Rainboth (1996) considered it ‘probably the commonest member of the genus in the Mekong’ and in a 2008 study of balitorid habitats in centra…

Most records pertain to the Mekong River basin downstream of the Khone waterfalls in Laos and Cambodia, but this species is also known from some smaller river drainages in southern Thailand, including parts of the Mae Klong system. Type locality is ‘Khlong Fit at Ban Kraduk Chang, road 3157 from Trat to borai, about 2-3 kilometers after junction w…
