Abstract

Amblyceps carinatum, a new species of hillstream catfish from the middle Irrawaddy River drainage in Myanmar is described here. It can be distinguished from congeners in having a unique combination of the following characters: the adipose fin in the form of a long, low ridge (length of adipose-fin base 37.5â??44.6% SL), a smooth posterior edge of the pectoral spine, poorly developed pinnate processes along the median caudal-fin rays, a deeply forked caudal fin, body depth at anus 13.1â??15.0% SL, head depth 10.6â??13.6% SL, eye diameter 9.4â??11.8% HL vs. 8.3), 39â??40 vertebrae, and a uniform body coloration. The valid species of Amblyceps are listed. The status of A. apangi and A. arunachalensis are discussed; the former species is considered valid and the latter a junior synonym of A. mangois. Amblyceps mucronatum is also recorded from the Irrawaddy River drainage for the first time.
