The type series was collected from a blackwater stream in Toh Daeng Peat swamp forest with the fish found in slow-moving or standing habitats among submerged shoreline roots and leaf litter. In the Tapi River floodplain it was collected from stagnant waters, one of which was an oxbow lake approximately 200 m long and 30 m across at its widest point, surrounded by ‘freshwater scrub and swamp trees’. The substrate was composed of mud, woody structures including fallen twigs and branches, and decomposing plant material.

The water at the type locality is described as ‘clear and fast-flowing over a rocky substratum’. H. parclitella was observed in shallow water among the rocks, and sympatric species included Garra cambodgiensis, Neolissochilus soroides, Poropuntius smedleyi, ‘Puntius‘ binotatus, Homaloptera nebulosa and Amblyceps mangois.

This species has been available in the trade for decades during which time it’s been widely misidentified as the valid congeners K. bicirrhis or, more recently, K. minor.

Its identity was not resolved until early 2013 meaning you will find it under one of these two names in the majority of literature published prior to that date.

Other trade names include ‘Asia…
