Juveniles: no scales on fins, except tail; operculum and nape scaled; no scales on cheek and occiput (Ref. 74422).Coloration: grey to beige; black margin on dorsal fin absent or only very thin, shorter and less conspicuous than in N. walteri; yellow-brown vertical stripes between the rays on all fins, except the pectoral; dorsal and anal fin with diagonal stripe pattern to direction of rays, about 4 stripes cross each ray; on caudal fin stripes perpendicular to rays (about 6 stripes); on pelvic fin stripe pattern more or less perpendicular to rays; in preserved specimens colour of fins not or less discernible, banded patterns visible; yellow brown vertical stripes on fins hardly noticeable when observing the fish in their habitat; pectoral fin yellow at distal end; iris light iridescent blue; blue suborbital stripe, as found in many lamprologines, in location of sensory groove; posterior margin of scales brownish (Ref. 74422).Juveniles: brown, smallest examined specimen almost yellow (16.9mm SL); no bands on body; tail emarginate; no filaments on tail or anal and dorsal fins; pelvic fins blackish; dorsal and anal fin dark to a lesser degree, no vertical stripes on fins; margin of dorsal fin black; little spots on head (Ref. 74422).
