Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335); devosi: The species is named in honour of Luc (Tuur) De Vos, an outstanding Belgian ichthyologist, in recognition of his remarkable collecting efforts and scientific determination; he was the first to recognise this species as new to science (Ref. 92865).

Diagnosis: 'Barbus' devosi belongs to the 'B.' eutaenia / 'B.' miolepis species-complex, because of its ossified and serrated last unbranched dorsal-fin ray and a live colour pattern including orange fins and a black mid-lateral stripe (Ref. 92865). It differs from the allopatric members of the complex by the following unique combination of characters: more gill rakers on the ceratobranchial of the first gill arch, 6-9 vs. 2-5 for 'B.' eutaenia and 'B.' miolepis; shorter anterior barbel, 11-19% of head length vs. 20-35% for 'B.' eutaenia and 20-37% for 'B.' miolepis; shorter posterior barbel, 15-27% of head length vs. 22-44% for 'B.' eutaenia and 27-46% for 'B.' miolepis; and the absence of a sheath of enlarged, prominent scales at the base of the dorsal fin as found in 'B.' eutaenia and 'B.' miolepis (Ref. 92865). 'Barbus' devosi differs from 'B.' choloensis by; fewer circumpeduncular scales, 10-12 vs. 14-16; fewer lateral line scales, 24-27 vs. 28-30; fewer scales between the lateral line and the anterior origin of the dorsal fin, 4,5 vs. 5-6; and it is a small to medium sized species, while 'B.' choloensis attains up to 200m standard length (Ref. 92865). 'Barbus' devosi differs from 'B.' seymouri by: more gill rakers on the ceratobranchial of the first gill arch, 6-9 vs. 4; its relatively shorter barbels, anterior barbel 31-64% of eye diameter vs. 46-96%, posterior barbel 46-87% of eye diameter vs. 71-123%; and fewer lateral line scales, 24-27 vs. 26-29 (Ref. 92865). Within the Lake Tanganyika drainage system 'B.' devosi is distinguished from all other small 'Barbus' by the following unique combination of characters: presence of a bony, serrated, last unbranched dorsal-fin ray; a complete lateral line; 24-27 lateral line scales; a permanent black mid-lateral stripe; and two pairs of barbels (Ref. 92865).
Colour: Dorsal and dorso-lateral parts of body and head dark brownish; flank grey silvery and ventral part whitish; a black mid-lateral stripe extending from tip of snout across eye and operculum to base of caudal fin and, in some specimens, onto mid-caudal fin rays, marking division between upper and lower lobes; mid-lateral stripe bordered dorsally and sometimes ventrally by a golden yellowish of whitish streak (Ref. 92865). Scales above lateral line darker at their edges (Ref. 92865). Dorsal and caudal fins grey-yellowish to grey-whitish with pinkish-orange tips; small specimens with more extended pinkish-orange colour on caudal and dorsal fins; pectoral fin grey yellowish to whitish, pelvic and anal fins translucent (Ref. 92865). Barbels with silvery grey base and whitish tip (Ref. 92865). Dorsal parts of preserved specimens dark brown; flank and belly grey to grey-yellowish; mid-lateral stripe dark brown or brown, less pronounced on snout in some specimens; barbels with dark base and yellowish tip; fins whitish and translucent; scales with darker edges visible in some specimens (Ref. 92865).
It is found in a rather slow running stream with very clear water, sandy and gravelled bottom and banks dominated by grassy vegetation (Ref. 92865). Probably rarely enters the main course of Malagarazi River (Ref. 92865).
