Members of this assemblage can be told apart from other congeners by possession of 44–46 vertebrae, an adipose-fin with a relatively short base (< 20 % SL), a colour pattern comprising either distinct black spots arranged in vertical columns or irregular black vertical lines running along the flanks, and normally a reddish or orangish caudal-fin in life.

This rarely-traded species is a member of the H. ocellata 'group' of closely-related congeners, an assemblage which currently comprises H. ocellata, H. bilineata, H. confuzona, H. orthogoniata, H. ogilviei and H. parclitella. Following Tan and Ng (2005) these share possession of a colour pattern with reddish tints and dark brown head markings, elongate head, slightly compressed body, 61-77 lateral line scales and dorsal-fin origin placed in advance of pelvic-fin origin.

It's a member of the N. selangoricus group of species within the genus, an assemblage first recognised by Hadiaty and Kottelat (2009) and characterised by possession of two rows of horizontally-arran...

Patterning is highly variable depending both within and between populations and the species may comprise an assemblage containing a number of taxa (Kottelat and Lim, 1993; Tan and Kottelat, 2009). For example, those from Singapore and Johor possessing intricate mottling on the dorsal surface while individuals from Terengganu have a series of saddle-like markings either alternating or connecting with the midlateral markings.

Parosphromenus spp. have been grouped arbitrarily based on courtship behaviour in males which adopt a 'head-down', 'head-up', or 'horizontal' position depending on species. P. harveyi belongs to the former, most abundant, assemblage in which the male assumes a near-vertical position with the head lowermost and fins splayed during nuptial displays.

Within this assemblage P. manipurensis is most similar to 'P.' meingangbii and P. padamya by virtue of the fact that males in all three possess orange-red pigmentation on the flanks and caudal-fin. It can be told apart most easily by the fact it possesses a relatively small, spot-like humeral marking, vs. a vertically-elongated, relatively large humeral marking in both the other species.

This fish has been widely misidentified and sold as the congener P. tiantian and its vernacular name of 'Burmese bumble-bee barb' but actually appears to be an undescribed member of the genus Pethia. This assemblage was erected by Pethiy...

This species is sometimes traded as 'Lake Inle red-tailed loach' and was formerly included in the genus Yunnanilus, a diverse assemblage of which the majority of members are endemic to the Yunnan plateau in Yunnan province, southern China.

This species is traded on a fairly regular basis and is similar in appearance to some congeners, most notably S. bella, S. mahnerti, S. multifasciata, S. poculi, S. reticulata, S. longa, S. conirostris and S. udomritthiruji. This assemblage has been referred to as the Schistura multifasciata 'group', and members share a...
