Batasio feruminatus, a new species of bagrid catfish from Myanmar (Siluriformes: Bagridae), with notes on the identity of B. affinis and B. fluviatilis

Abstract

Batasio feruminatus, new species, is described from the Ataran River drainage in Myanmar. It is distinguished from congeners in having the base of the adipose fin in contact with (vs. separate from) the base of the last dorsal-fin ray and in having a color pattern on the body consisting of both an oblique predorsal bar and a thin longitudinal black stripe. The identities of B. affinis and B. fluviatilis are also discussed; the former species is rediagnosed and B. niger is a junior subjective synonym, and B. fluviatilis is a senior subjective synonym of B. havmolleri. © 2007 by Verlag Dr. Friedrich Pfeil.
