Diagnostic Description

Tanganikallabes alboperca is distinguished from all congeners by having relatively shorter pelvic fins (6.0-7.7% SL versus 7.1-9.3% SL in other Tanganikallabes species), which do not reach past the origin of the anal fin when adpressed (versus reaching past the anal fin origin in all other Tanganikallabes species) (Ref. 90118). It is also distinct from other Tanganikallabes species in the presence of a well-defined, depigmented border on the operculum, which extends from the upper margin of the operculum all the way to the union of the gill membranes at the isthmus (border absent in Tanganikallabes mortiauxi and Tanganikallabes stewarti) (Ref. 90118).
