Pseudobagrus nubilosus, a new species of catfish from central Vietnam (Teleostei: Bagridae), with notes on the validity of Pelteobagrus and Pseudobagrus

Abstract

Pseudobagrus nubilosus, new species, is described from the Song Vinh Tranh river drainage in central Vietnam. It is easily distinguished from congeners in having fewer branched anal-fin rays (9-10 vs. 13-22) and a unique combination of: dorsal-spine length 14.0-16.9 % SL, pectoral-spine length 13.6-16.7 % SL, length of adipose-fin base 10.6-14.3 % SL, smooth anterior edge of the pectoral spine, and a color pattern consisting of cream blotches on a brown body. The evidence for Pelteobagrus and Pseudobagrus as natural groups is also reviewed and discussed. Pelteobagrus is hereby considered a junior synonym of Pseudobagrus. © 2007 by Verlag Dr. Friedrich Pfeil.
