Etymology: Tanganikallabes: Composed from lake Tanganyka + Greek, allabes, -etos = a fish of the Nile, a kind of lamprey (Ref. 45335); stewarti: The specific epithet of this species is a patronym in honour of American ichthyologist Donald J. Stewart, who collected the holotype and other material used in the description of this species, as well as assisting in the collection of much of the type series of Tanganikallabes alboperca (Ref. 90118).

Short description
Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά): 0; Μαλακές ραχιαίες ακτίνες (συνολικά): 72-79; Εδρικές άκανθες 0; Μαλακές εδρικές ακτίνες: 63 - 69. Diagnosis: Tanganikallabes stewarti is distinguished from all congeners by having an incomplete lateral line, which terminates at a vertical through a point approximately two-thirds of the distance along the anal fin base, vs. lateral line reaching the caudal peduncle in T. mortiauxi and extending much closer to the caudal peduncle in T. alboperca ; and by its relatively shallower body, body depth at anus 8.7-10.9% of standard length vs. 12.3-17.2% in T. mortiauxi and 11.7-14.6% in T. alboperca (Ref. 90118). Tanganikallabes stewarti is further separated from T. mortiauxi by its premaxillary toothpad shape, uniformly thin, broad crescent, vs. widest point anteroposteriorly thicker; lack of a free lower orbital margin; io-iv and the suprapreopercle consisting of multiple separate elements, vs. a single element; the extensions of the lateral ethmoid not reaching io-ii when viewed from above, vs. nearly or completely overlaying io-ii; its proportionally shorter prepelvic length, 35.7-39.2% of standard length vs. 39.7-44.4%; its proportionally shorter preanal length, 42.4-44.8% of standard length vs. 47.1-51.7%; longer anal fin, anal fin base 54.1-58.9% of standard length vs. 47.6-54.2% (Ref. 90118). It can additionally be distinguished from T. alboperca by its lack of a depigmented opercular margin; having longer pelvic fins, 7.1-9.3% of standard length vs. 6.0-7.7%, which reach beyond the origin of the anal fin when adpressed; proportionately longer pectoral fin spines, 5.0-6.8% of standard length vs. 3.6-5.3%; a shorter preanal length, 42.4-44.8% of standard length vs. 45.2-49.0%; and a generally higher number of dorsal fin rays, 72-79 vs. 65-74, and anal fin rays, 63-69 vs. 55-63 (Ref. 90118).
It is likely to inhabit rocky bottoms, over a range of depths (Ref. 90118).
