🐟 Physical Description

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 13 - 15; Anal spines: 3; Anal soft rays: 10. Diagnosis: The presence of ocelli throughout the anal fin of breeding males distinguishes Serranochromis swartzi from S. robustus and S. jallae in which the ocelli in breeding males are restricted to the posterior 4-5 membranes of the anal fin . The exposed teeth of S. swartzi differs from those of S. stappersi and S. altus, which possess small teeth that are burried in the lips; Serranochromis swartzi has an emarginate caudal fin, while S. macrocephalus, S. janus, and S. angusticeps have rounded caudal fins; the shorter jaw of S. swartzi, 44.4-52.0% of head length, separates it from S. spei, 53.5-57.2% of head length; Serranochromis swartzi has 34-37 lateral-line scales, while S. thumbergi possesses more than 39 lateral-line scales; the acute angle of the cleft of the mouth, 50-60° of horizontal, of S. meridianus delimits it from the 25° angle of S. swartzi; the long dark pectoral fins which reach past the middle of the dorsal fin separates S. longimanus from S. swartzi . The interorbital width, 14.3-15.9% of head length, of S. alvum is narrower than that of S. swartzi, 17.6-19.8% of head length; Serranochromis swartzi has a smaller preorbital depth, 16.2-18.9% of head length, and snout length, 29.6-31.9% of head length, than S. cuanza, 19.1-22.2% and 35.2-39.6% respectively; the greater preorbital depth, 19.1-22.2% of head length, of S. swartzi distinguishes it from S. cacuchi, which has a smaller preorbital depth, 11.3-15.5% of head length .
