New Mystus

Post by Silurus »

Sudasinghe, H, R Pethiyagoda, K Maduwage & M Meegaskumbura, 2016. Mystus nanus, a new striped catfish from Sri Lanka (Teleostei: Bagridae). Ichthyological Exploration of Freshwaters 27: 163–172.

Abstract

Mystus nanus, new species, is described from lowland streams, rivers and reservoirs throughout Sri Lanka. Previously misidentified in Sri Lanka as M. vittatus, the new species is distinguished from its Indian and Sri Lankan congeners by having two cream stripes along the flanks, a black hypural blotch, the distal margin of the dorsal fin rounded, eye diameter 19-22 % head length, adipose-fin base length 25.3-31.4 % standard length, and the posterior cranial fontanelle ending about an eye-diameter anterior to the base of the supraoccipital process.
