Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11; Spine anali: 0; Raggi anali molli: 8; Vertebre: 32. Diagnosis: Enteromius vandewallei is distinguished from all other Enteromius species of West Africa by the following unique combination of characters: last simple dorsal-fin ray smooth on posterior margin, vs. denticulate in E. cadenati, E. carcharhinoides, E. dialonensis and E. guineensis; 4.5 scales between dorsal-fin base and lateral line, vs. 5.5 in E. subinensis and 3.5 in E. ablabes, E. aboinensis, E. aliciae, E. anema, E. baudoni, E. bawkuensis, E. callipterus, E. clauseni, E. eburneensis, E. guildi, E. huguenyi, E. liberiensis, E. macrops, E. melanotaenia, E. niokoloensis, E. parablabes, E. pumilus, punctitaeniatus, E. raimbaulti, E. teugelsi, E. trispiloides, E. walkeri and E. zalbiensis; two pairs of barbels, vs. no barbels in E. leonensis, E. salessei, E. stigmatopygus and E. sylvaticus, and only one pair in E. pobeguini; no spots on the flanks, vs. spots present in E. anniae, E. boboi, E. camptacanthus, E. lauzannei, E. macinensis, E. perince, E. sublineatus, E. tiekoroi, E. traorei and E. trispilos; 12 scale rows around caudal peduncle, vs. 9-10 in E. inaequalis and 10 in E. ditinensis; a black band in the middle of the flanks, vs. no band in E. bagbwensis and E. foutensis; long barbels, the anterior pair reaching the posterior half of eye, the posterior one reaching the front edge of the pre-opercula, vs. short barbels, the anterior pair falling short of eye, the posterior sometimes extending beyond center of eye in E. atakorensis; 8 branched dorsal-fin rays, vs. 7 in E. atakorensis; lateral line clearly depressed below the dorsal fin, vs. lateral line straight in E. chlorotaenia and E. bigornei; head length 26.4-28.4% of standard length, vs. 22.6-25.7% in E. nigeriensis; interorbital width 22-27% of head length, vs. 27-36% in E. nigeriensis; and with a rather narrow, black, longitudinal band covering less than 0.5 scale in the middle of the flanks and rising about 1 scale above lateral line at the level of the dorsal fin, vs. longitudinal band, whenever present, often wider, covering more than 0.5 scale in the middle of the flanks while rising only about 0.5 a scale above the lateral line in E. nigeriensis (Ref. 114035).
Body shape (shape guide): fusiform / normal.
