Etymology: Serranochromis: Latin, serra = saw + Greek, chromis = a fish, perhaps a perch (Ref. 45335); cuanza: The specific name cuanza, a noun in apposition, refers to the Cuanza River, spelt as generally done in Angola; the species is most likely endemic to the Cuanza River system (Ref. 123822).

Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 15; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 12-14; गुदा कांटा 3; ऐनल सौफट रेज़: 9 - 11. Diagnosis: The presence of ocelli throughout the anal fin of breeding males distinguishes Serranochromis cuanza 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 (Ref. 123822). The exposed teeth of S. cuanza differs from those of S. stappersi and S. altus, which possess small teeth that are buried in the lips; Serranochromis cuanza has an emarginate caudal fin, while S. macrocephalus, S. janus, and S. angusticeps have rounded caudal fins; the shorter jaw of S. cuanza, 44.3-52.8% of head length, separates it from S. spei, 53.5-57.2% of head length; Serranochromis cuanza has 36-37 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. cuanza; the long dark pectoral fins which reach past the middle of the dorsal fin separates S. longimanus from S. cuanza (Ref. 123822). The interorbital width of S. cuanza, 16.3-18.0% of head length, is narrower than that of S. cacuchi, 20.0-21.7% of head length; Serranochromis cuanza has a greater preorbital depth, 19.1-22.2% of head length, and snout length, 35.2-39.6% of head length, than S. swartzi, 16.2-18.9% and 29.6-31.9% of head length respectively; the interorbital width of S. cuanza, 16.3-18.0% of head length, is wider than that of S. alvum, 14.3-15.9% of head length (Ref. 123822).
