Intraspecific variation: (1) with increasing size the preanal length decreases proportionally to the increase of the postanal length; (2) the preorbital spine, if present, has a tendency to disappear with size; in small specimens, the presence/absence of a preorbital spine may vary according to the basin of origin; (3) preopercular spines, if present, have a tendency to decrease in number with size; the number of preopercular spines may vary considerably between specimens of the same basin; (4) the number of dorsal spines shows an important amount of geographical variation (Ref. 81678).Coloration: In preservation: overall colour uniformly brown; upper sides and dorsal mid-line lighter brown with a series of small dark brown spots on dorsal mid-line, extending along dorsal, caudal and anal fin bases; generally a dark brown band originating at base of rostral appendage and continuing posteriorly along sides of body and tail; upper edge of lateral band with a well delimited battlement-like pattern and lower edge ill defined; some specimens with more uniformly coloured dark brown sides; ventral side of head, belly, and abdomen lighter brown or whitish with virtually no markings; exceptionally, a dark brown netting around pectoral fin region; general colour of dorsal, caudal and anal fins whitish; dorsal fin with an additional series or a somewhat more irregularly displaced sequence of small dark brown spots; anal fin also with such an additional series, sometimes with a few additional dark brown spots situated on posterior half of fin; caudal fin with a single, or in some specimens two, large dark brown spot(s); pectoral fins whitish with no or sometimes a few, dark brown spots; unpaired fins darker in larger specimens; Congo River basin specimens generally with a more developed netting pattern surrounding large yellowish white spots on the lower flanks (Ref. 81678).
