Etymology: Serranochromis: Latin, serra = saw + Greek, chromis = a fish, perhaps a perch (Ref. 45335); alvum: The specific name, alvum, a noun in apposition, is derived from the Latin, which means blotches and refers to the prominent lateral pigmentation (Ref. 123822).

पृष्ठीय रीढ़ (सम्पूर्ण) : 14 - 15; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 13 - 15; गुदा कांटा: 3; ऐनल सौफट रेज़: 9 - 10. Diagnosis: The presence of ocelli throughout the anal fin of breeding males distinguishes Serranochromis alvum 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. alvum differs from those of S. stappersi and S. altus, which possess small teeth that are buried in the lips; Serranochromis alvum has an emarginate caudal fin, while S. macrocephalus, S. janus, and S. angusticeps have rounded caudal fins; the shorter jaw of S. alvum, 43.4-53.5% of head length, separates it from S. spei, 53.5-57.2% of head length; Serranochromis alvum has 34-36 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 30° angle of S. alvum; the long dark pectoral fins which reach past the middle of the dorsal fin separates S. longimanus from S. alvum; 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, S. cuanza, 16.3-18.0% of head length, and S. cacuchi, 20.0-21.7% of head length (Ref. 123822).
Found in riverbed which was mostly sand substrate with occasional marginal aquatic weed beds and fringing emergent beds of Phragmites (Ref. 123822).
