Africa: present throughout the Congo River basin (Ref. 78218). In the Lukuga (Tanganyika outflow) up to the Kisimba-Kilia rapids (Ref. 93587). Reports of this species from Inga and the Luongo River (Zambian Congo) refer to Congoglanis inga and C. sagitta, respectively (Ref. 88958). Reports from the Luachimo River (Ref. 11970) are C. howesi (Ref. 92838).

背棘 (總數) : 0; 背的軟條 (總數) : 8; 臀棘: 0; 臀鰭軟條: 9 - 11. Diagnosis: Congoglanis alula differs from C. inga in having a shorter maxillary barbel not reaching to vertical through anterior margin of orbit, vs. extending well past anterior margin of orbit, respectively; a longer pelvic fin, 24–28% of standard length, vs. 19–21%; a shorter postorbital length, 27–31% of head length, vs. 32–35%; a relatively narrow interorbital width, 1.5 times eye diameter, vs. 2 times; and shorter anal-fin rays, posterior rays of adpressed anal fin extend to, rarely slightly beyond, vertical through posterior limit of adipose fin, vs. posterior rays extend well past vertical through posterior limit of adipose fin (Ref. 88958). Congoglanis alula differs from C. sagitta in having a longer pectoral fin, 28–29% of standard length, vs. 23–27%; a longer pelvic fin, 24–28% of standard length, vs. 19–21%; a shorter caudal peduncle, 18–22% of standard length, vs. 21–24%; and deeper caudal peduncle, caudal-peduncle depth 2.6–3.3 times in caudal-peduncle length, vs. 3.1–4.0 times; a relatively narrow interorbital width, 1.5 times eye diameter, vs. 2 times; a more posteriorly placed anal fin, anal-fin origin approximately at tip of adpressed pelvic fin, vs. origin well in advance of tip of adpressed pelvic fin; and fewer vertebrae, 36–39, vs. 39–41 (Ref. 88958).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Typically found in fastest flowing portions of rivers and always associated with large rocks; appears to congregate underneath rocks near where water breaks over the rocks during the day, and will move out onto the tops of rocks at night (Ref. 88958).
