背棘 (总数) : 0; 背的软条 (总数) : 11; 臀棘: 0; 臀鳍软条: 8. 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).
背面轮廓直线。 非常小的嘴。 侧线不完全的,4-6个有排孔的鳞片。 淡灰色的身体。 一些黑色素细胞沿着中央的线。 头部的背面颜色深的。 背鳍与臀鳍有 3个单一的鳍条。
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).
分类相关: 表面地类似 B. salessei(侧线完整, 没有触须) 。 (参考文献 2940) 最大体长TL记录为 4.2 公分。 (参考文献 2801)
