Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 7-8; Anal spines: 0; Anal soft rays: 10 - 11; Vertebrae: 35 - 37. Diagnosis: Congoglanis inga differs from C. sagitta in having a longer maxillary barbel, reaching well past vertical through anterior margin of orbit vs. not reaching to orbit; a deeper caudal peduncle, 7-8% of standard length vs. 6%; and less slender caudal peduncle, its depth 2.1-2.9 times in its length vs. 3.1-4.0; a longer pelvic fin, 22-25% of standard length vs. 19-21%; 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; longer anal-fin rays, posterior rays of adpressed anal fin extend well past vertical through posterior limit of adipose fin vs. posterior rays extend to vertical through posterior limit of adipose fin; and fewer vertebrae, 35-37 vs. 39-41 (Ref. 88958). It differs from C. alula in having a longer maxillary barbel, reaching well past vertical through anterior margin of orbit vs. not reaching the orbit; a shorter pelvic fin, 19-21% of standard length vs. 24-28%; a longer postorbital length, 32-35% of head length vs. 27-31%; a relatively wide interorbital width, 2 times eye-diameter vs. 1.5 times; and longer anal-fin rays, posterior rays of adpressed anal fin extend well past vertical through posterior limit of adipose fin vs. posterior rays extend to vertical through posterior limit of adipose fin (Ref. 88958).

Specimens have been collected from "a long channel with moderate current, numerous pools and a predominantly rocky bottom" (Ref. 42510, 88958).
