Pseudecheneis koladynae, a new species of sisorid catfish, is described from the Koladyne basin of Mizoram State, India by eminent ichthyologist from Manipur University, Prof Vishwanath and Dr Anganthoibi, published in Ichthyological Exploration of Freshwaters
Diagnosis:Pseudecheneis koladynae is distinguished from its congeners by the following combination of characters: three isolated ovoid yellow nuchal patches, one in mid-dorsal line in front of dorsal-fin origin and two on either side of the middle spot, slightly behind; prominent bony spur on the antero-dorsal surface of the first dorsal-fin pterygiophore; short caudal peduncle (length 16.0-18.8 % SL); pelvic fin not reaching the base of the first anal-fin ray; and distinct sexual dimorphism with robust conical papilla in males and flat leaf-like comparatively smaller bilobed papilla with a small mid-ventral lobe in females.
