Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335); zakoni: This species is named in honor of Harold H. Zakon; in addition to his many contributions to neuroethology, which inspires a new area of research on genes that underlie electrolocation and electrical communication in gymnotiform and mormyroid fishes (Ref. 85331).

Diagnosis: Petrocephalus zakoni is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 23 or 24 branched rays; anal fin with 27 or 28 branched rays; eye large, the ratio head length and eye-diameter between 3,1 and 3,3; mouth small, the ratio head length and mouth width between 4.4 and 5.0; 10 teeth of fewer in the upper jaw; and 22 teeth or fewer in the lower jaw (Ref. 85331). It has a unique pigmentation pattern consisting of three well defined black patches: (1) an intense dark mark on each side of the body close to the anterior base of the dorsal fin, often extending onto the first dorsal rays, forming a characteristic saddle across the dorsum; (2) a mark on each side of the body at the base of the pectoral fin; (3) a crescent-shaped mark on each side of the body centered at the base of the caudal fin, extending onto the upper and lower parts of the caudal fin (Ref. 85331).
