Abstract: Gogo atratus is a new species of anchariid catfish described from the Mananara du Nord River drainage in northeastern Madagascar. It can be distinguished from congeners by a longer snout (54.8-56.4% HL, vs. 47.1-54.3 in congeners) and faintly mottled dark gray coloration (vs. uniform brown, highly mottled dark gray and cream, or mottled brownish-gray). The following combination of characters further distinguishes Gogo atratus from congeners: dorsal-spine length 17.7-20.6% SL, pectoral-spine length 16.5-18.9% SL, length of adipose-fin base 23.6-27.8% SL, head width 17.8-18.9% SL, interorbital distance 28.9-30.5% HL, eye diameter 13.0-14.3% HL, unicuspid teeth, and straight dorsoposterior margin of dorsal fin. © 2008 by the American Society of Ichthyologists and Herpetologists.
