Etymology: Serranochromis: Latin, serra = saw + Greek, chromis = a fish, perhaps a perch (Ref. 45335); cacuchi: The specific name cacuchi, a noun in apposition, refers to the Cacuchi River where this species was collected and is most likely narrowly endemic (Ref. 123822).

الأشواك الظهرية (المجموع) : 14 - 15; الأشعة الظهرية الناعمة (المجموع) : 12 - 13; شوكة شرجية: 3; أشعه شرجية لينه: 9. Diagnosis: The presence of ocelli throughout the anal fin of breeding males distinguishes Serranochromis cacuchi 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. cacuchi differs from those of S. stappersi and S. altus, which possess small teeth that are buried in the lips; Serranochromis cacuchi has an emarginate caudal fin, while S. macrocephalus, S. janus, and S. angusticeps have rounded caudal fins; the shorter jaw of S. cacuchi, 47.8-52.3% of head length, separates it from S. spei, 53.5-57.2% of head length; Serranochromis cacuchi has 32-33 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. cacuchi; the long dark pectoral fins which reach past the middle of the dorsal fin separates S. longimanus from S. cacuchi (Ref. 123822). The interorbital width, 20.0-21.7% of head length, delimits S. cacuchi from S. alvum, 14.3-15.9% of head length; the snout length of S. cacuchi, 35.2-39.6% of head length, is longer than that of S. alvum, 30.3-34.9% of head length, and S. cuanza, 26.9-34.7% of head length; the larger preorbital depth of S. cacuchi, 19.1-22.2% of head length, distinguishes it from S. swartzi, 16.2-18.9% of head length (Ref. 123822).
