Enteromius clauseni (Thys van den Audenaerde 1976)

Diagnosis: last simple dorsal-fin ray smooth on hind margin; scale formula 3.5/22-25/4.5-5.5; 3-3.5 scales between lateral line and pelvic-fin base; 4-6 anterior scales pored; 10 scales around caudal peduncle; lateral-line scales without particular colour pattern; 8 branched dorsal fin rays; no barbels; lateral line incomplete, straight; maximum reported size 30 mm SL; small spot at end of caudal peduncle (Ref. 2940, 81282). Description: small species with straight dorsal profile; mouth very small, inferior, without barbels; D:III,8; A:III,5; V:I,7 (Ref. 2940, 81282).Coloration: body light grey; small black mid-lateral spot at end of caudal peduncle; some melanophores along midline of sides on posterior part of body; occiput strongly pigmented (Ref. 2940, 81282).

Dorsal spines (total): 0; Dorsal soft rays (total): 11; Analspines: 0; Analsoft rays: 8

Affinities: superficially similar to B. salessei (complete lateral line, without barbel); B. clauseni is also related to B. sylvaticus, the latter having only 8 scales around the caudal peduncle and no pored scales in the lateral line; the distance between the type localities of these two species is only 100 km (Ref. 2940). Maximum TL was recorded at 4.2 cm (Ref. 2801).
