Devi, KB, I Linthoingambi & KR Singh, 2023. A new sisorid catfish of the genus Glyptothorax Blyth (Teleostei: Sisoridae) from Kasom Khullen of Manipur, India. Records of the Zoological Survey of India 123: 29–41.
Abstract
Glyptothorax lairamkhullensis, new species, is described from the Taretlok River, a tributary of the Chindwin Basin in Kasom Khullen, Manipur, India. The new species is very similar to G. ventrolineatus but can be distinguished from it in having ventral surface of pectoral and pelvic fins pleated (vs not pleated or smooth) and dorsal-fin spine not serrated (vs finely serrated at tip). The new species has a U-shaped adhesive apparatus open caudally; broader than its length and not extending up to the gular region; interdorsal distance (22.7-26.9% SL); claspers present at anus. Congeners from the Chindwin basin of Manipur have the ventral surface of paired fins smooth. The present species is unique in having pleated skin on paired fins.
