摘要
The highly specialized akysid catfish genus Breitensteinia is revised; two new species are described. Breitensteinia cessator is described from Sumatra and western Borneo. It can be distinguished by its large, wide-set eyes and evenly scattered brown spots on the dorsal and pectoral fins. Breittensteinia hypselurus is described from western Borneo. It can be distinguished by its relatively tall neural spines on caudal verterbrae, smooth posterior edge of dorsal spine, short caudal peduncle, and fewer vertebrate. Briettensteinia insignis is sexually dimorphic. (C) 1998 The Fisheries Society of the British Isles.
