A new species of bagrid catfish has been described from Sri Lanka in a recent issue of the journal Ichthyological Exploration of Freshwaters.
Naming the new species Mystus ankutta after the generic Sinhala name for small catfishes, Rohan Pethiyagoda, Anjana Silva and Kalana Maduwage distinguish it from congeners in Peninsular India and Sri Lanka in having a combination of: adipose fin height 6.5"7.5% SL, absence of markings on the body except for a diffuse humeral spot and a dark triangular blotch on the caudal peduncle, eye diameter 18"23% SL, caudal-peduncle depth 10.1"12.3% SL and length of upper caudal-fin lobe 27.6"32.2% SL.
Mystus ankutta is only known from rivers in southwestern Sri Lanka.
