Etymology: Tanganikallabes: Composed from lake Tanganyka + Greek, allabes, -etos = a fish of the Nile, a kind of lamprey (Ref. 45335); alboperca: The specific epithet, 'alboperca', is derived from the latin adjective 'alba', meaning white, and the noun 'operculum', meaning lid or cover, in reference to the distinctive depigmented posterior margin seen in the operculum of this species (Ref. 90118).
Environment / Climate / Range
Freshwater; benthopelagic. Tropical, preferred ?
Africa: endemic to Lake Tanganyika, found in the extreme southern and northern parts of the lake (Ref. 90118).

Max length : 16.1 cm SL male/unsexed; (Ref. 90118)
Morphology | Morphometrics
soft rays: 55 - 63. 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).
Likely to inhabit rocky bottoms over a range of depths; fish eggs, crab remnants and insect larvae have been found in stomach (Ref. 90118).
