Etymology: djeremi: After the type locality of this species, the River Djerem, Cameroon (Ref. 43912).
Meio ambiente: milieu / Zona climática / intervalo de profundidade / faixa de distribuição
Ecologia
; Água doce demersal. Tropical; 6°N - 5°N
Africa: endemic to the Sanaga River in Cameroon (Ref. 43912, 81643).
Tamanho / Peso / Idade
Maturidade: Lm ? range ? - ? cm
Max length : 17.2 cm SL macho/indeterminado; (Ref. 81643)
Espinhos dorsais (total) : 1. Diagnosis: adipose fin present (Ref. 43912, 81643) and fully developed (Ref. 81643). Inner side of pectoral fin spine weakly serrated (Ref. 43912, 81643). Barbels well developed (Ref. 81643), nasal barbels always extend beyond posterior edge of orbit (Ref. 43912, 81643) and may almost reach posterior edge of opercle (Ref. 81643). Maxillary barbel not reaching beyond head; eye diameter 26.2-30.5% HL (Ref. 43912). Posterior nostrils at same distance (Ref. 43912, 81643) or slightly closer to each other than are anterior ones (Ref. 81643). 43-51 branched anal fin rays (Ref. 43912, 81643). Lower jaw always shorter than upper jaw (Ref. 43912, 81643) and completely surrounded by upper lip when mouth is closed (Ref. 43912). Moderately sized species (less than 20 cm SL)(Ref. 81643). Colour pattern characterized by brown back and head, large dark brown stripe along lateral line and oblique brown stripe from below anterior part of lateral line to origin of anal fin (Ref. 43912).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Stomach contents of a specimen from the Upper Sanaga showed the presence of insect remains (adult Hymenoptera,
Odonata larvae and other unidentified aquatic insect
larvae)(Ref. 43912). Oviparous, eggs are unguarded (Ref. 205).
