| Diagnose |
Diagnosis: Dorsal fin up to 1.5 times in length of anal fin; origin of dorsal fin in advance of anal fin (Ref. 52193). Snout rounded, in front of mouth; eye well above mouth; chin with fleshy bulge (Ref. 4967). For distinguishing between specimens of Cyphomyrus discorhynchus en C. cubangoensis, the most useful anatomical characters are: longer dorsal fin length, longer anal fin length, higher number of dorsal fin rays and anal fin rays, and a higher caudal peduncle depth and caudal peduncle length ratio in C. discorhynchus than in C. cubangoensis (Ref. 119538). Description: Body relatively deep, compressed (Ref. 52193). Head rounded with blunt snout, mouth with mental lobe, teeth biscuspid, 5-6 in each jaw (Ref. 52193). Teeth in upper jaw 4-7; teeth in lower jaw 5-8 (Ref. 122874). Dorsal fin longer than anal, dorsal fin origin before anal fin origin, caudal fin forked, with round lobes; dorsal-fin rays 28-37; anal-fin rays 23-27; pectoral-fin rays 10-11; pelvic-fin rays 6 (Ref. 52193, 122874). Scales on lateral line 57-73; circumpeduncular scales 12-13; scales between dorsal and anal fins 28-31; scales between dorsal fin and lateral line 15-17; scales between pelvic fin and lateral line 14-17 (Ref. 52193, 122874). Total number of vertebrae 39-41 (Ref. 122874). Colouration: Greyish brown to dark brown, nearly black, lighter below, dark vertical bar sometimes evident between dorsal and anal fins (Ref. 52193). |
