背棘 (总数) : 0; 背的软条 (总数) : 12 - 14; 臀棘: 0; 臀鳍软条: 10 - 11; 脊椎骨: 38 - 39. Diagnosis: Nannocharax signifer is distinguished from all other Nannocharax species in West Africa by the red-orange colouration of the anterior part of its dorsal fin (Ref. 85591). The combination of the following characters is also diagnostic: no continuous black band along the flank; multiple x-shaped body colour pattern extending on the lower half of the flank; 46-48 lateral line scales; and 4-5 scales between anus and origin of anal fin (Ref. 85591).
