Etymology: Bathyaethiops: Greek, bathys = deep + Greek, Aethiopia, an African country (Ref. 45335); atercrinis: Ater, from the Latin, meaning black or dark, and crinis, in the sense of the tail of a comet; named in reference to the striking black marking of the caudal peduncle and anal fin of mature males (Ref. 91757).

背棘 (总数) : 0; 背的软条 (总数) : 9 - 10; 臀棘: 0; 臀鳍软条: 18 - 20; 脊椎骨: 33 - 35. Diagnosis: This species is distinguished from congeners by the possession of 21-24 scales in the longitudinal series vs. 28-42 scales, and from Brachypetersius altus by the possession of a short, abridged lateral line of 6 or 7 pored scales vs. a complete lateral line of 20-28 pored scales (Ref. 91757). Unique among related taxa in displaying marked sexual dichromatism, and dimorphism of the anal-fin skeleton; with medially expanded first anal-fin pterygiophores, markedly enlarged branched anal-ray segments, and strongly convex anal-fin profiles characterizing males; they also display a distinctive black blotch extending from just above midline behind the dorsal fin and passing ventrally over the anal fin (Ref. 91757).

This species was caught close to the bank of the river, at a depth of about 1 meter over sand and mud; banks covered with dense, undisturbed riparian vegetation consisting of large numbers of entangling lianas covering large trees which also bear many epiphytic orchids (Ref. 91757). Water temperature in the shallows where most specimens were collected was between 21.0-22.5°C and pH 7.6; water very turbid and current moderately rapid (Ref. 91757).
