Mystus zeylanicus, a new species of bagrid catfish from Sri Lanka (Teleostei: Bagridae)

Abstract

Mystus zeylanicus, new species, is described from lowland rivers and reservoirs of Sri Lanka. It differs from most South Asian congeners in having a long-based adipose fin, and differs from those having a similar-shaped adipose fin by mensural characters of the eye, head, dorsal-fin spine, body depth and caudal-peduncle depth, as well as its uniformly gray color pattern. The status of the other siluriform species known from Sri Lanka is also briefly discussed. © 2013 by Verlag Dr. Friedrich Pfeil.
