Glyptothorax ketambe, a new catfish (Teleostei: Sisoridae) from northern Sumatra

Abstract

Glyptothorax ketambe, a new species of sisorid catfish is described from the Alas River drainage in Nangroe Aceh Darussalam Province, northern Sumatra. Glyptothorax ketambe can be distinguished from all other Sundaic congeners except G schmidti and G siamensis in having a color pattern consisting of a dark brown body with yellowish midlateral and mid-dorsal stripes. It differs from G. schmidti and G. siamensis in having a combination of: caudal-peduncle depth 7.6-8.9% SL, head width 16.1-17.9% SL, thoracic adhesive apparatus not reaching to the level of the base of the last pectoral-fin ray, and thoracic adhesive apparatus with an almost straight lateral margin. The identity of G. schmidti is also clarified in this study. Copyright © 2009 Magnolia Press.
