The status of the seven synonyms to this species is not finalised. Certainly Nemacheilus liboensis and Oreonectes liboensis are nomina nuda. Paracobitis longibarbatus is the original generic placement of the species before it was moved to Triplophysa. The species posterodorsalus and maolanensis are treated as vaild by some authors (e.g. Yang, Wu and Lan 2011, Wu, He, Yang and Du 2018), and as synonyms of T. longibarbata by othes (e.g. Du et al. 2008, Romero et al. 2009, Kottelat 2012:128). More data are required to elucidate the final position.
Holotype: KIZ 953001 70mm TL, 68mm SL. Paratypes: KIZ 953002 35mmTL, 29mm SL; KIZ 953003 36mm TL, 30mm SL.
Known only from the type locality: An unnamed cave 13 km north east of the town of Libo, Libo County, southern Guizhou, China (25o30’N, 107o50’E). This is in the Xijiang river basin.
The cave is 500m above sea level. Not far from the entrance shaft the cave stream ends at a 90m long lake which eventually sumps. The flow rate is 10l/sec and the substrate sand and rocks. Up to 10 animals were visible on each of three visits made by the explorers. The fishes live in total darkness but are sensitive to light, moving away from any light pointed at them. This species possibly coexists with Triplophysa macrocephala at the latters type locailty.
Related to, and probably descended from, Paracobitis variegatus longidorsalis, which occurs in the same (Xijiang) river basin. The generic position of these species is called into question by the opinion of Banarescu and Nalbant (1995:443) that “The genus is exclusively western Asian.” They place Paracobitis variegatus in the genus Homatula Nichols 1925 (though they incorrectly date this genus as 1929). Eschmeyer (1998:1970) consider the genus Homatula as a synonym of Schistura.
Yang, Wu and Lan (2011:570) consider Paracobitis posterodarsalus Li, Ran and Chen 2006 and Paracobitis maolanensis Li, Ran and Chen 2006 as valid species of Triplophysa.
