Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335).
Eponymy: Claus Herluf Stenholt Clausen (1921–2002) was a California-born Danish ichthyologist and biologist. He collected in Liberia (1965). He wrote: Tropical Old World Cyprinodonts (1967). He collected the holotype. (Ref. 128868), visit book page.

背棘 (總數) : 0; 背的軟條 (總數) : 11; 臀棘: 0; 臀鰭軟條: 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).
背面輪廓直線。 非常小的嘴。 側線不完全的,4-6個有排孔的鱗片。 淡灰色的身體。 一些黑色素細胞沿著中央的線。 頭部的背面顏色深的。 背鰭與臀鰭有 3個單一的鰭條。
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).
分類相關: 表面地類似 B. salessei(側線完整, 沒有觸鬚) 。 (參考文獻 2940) 最大體長TL記錄為 4.2 公分。 (參考文獻 2801)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00523 - 0.02406), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
