Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335); validus: Specific name, validus, from the Latin meaning strong or powerful, in reference to the robust appearance of the species (Ref. 106731).

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 11; Anale stekels: 0; Anale zachte stralen: 8; Wervels: 34 - 35. Diagnosis: It is distinguished from all other African smiliogastrin species by the following features that, in combination, uniquely diagnose the species: scales in midlateral series not enlarged relative to impinging rows above and below; barbels well developed, maxillary pair extending beyond level of mideye, mandibular pair reaching level of midopercle; numerous conical tubercles over snout and cheek, and dorsum of head; small circular occipital fontanel often present and located medially at parietal suture; gill rakers well developed, 8 or 9 on hypo- and ceratobranchial elements of first arch; last unbranched dorsal-fin ray weakly ossified, flexible, and lacking serrations along posterior edge; dorsal fin creamy white proximally, distal half to two thirds darkly pigmented (Ref. 106731).
This species is omnivorous and opportunistic (Ref. 106731). Gut contents contained disarticulated insect remains, woody debris, seeds, macerated grasses and terrestrial arthropod remains of spiders and ants (Ref. 106731). Specimens collected in June, July, and August showed no sign of maturation of ovaries or testes; most large individuals collected in March had enlarged testes or ovaries filled with numerous small, round eggs suggesting that peak breeding occurs at that time (Ref. 106731).
