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).
Eponymy: Dr Harold H Zakon is a Professor (since 1999) at the Department of Neuroscience, College of Natural Sciences at the University of Texas, as well as Chairman of Neurobiology. [...] (Ref. 128868), visit book page.

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).
Body shape (shape guide): fusiform / normal.
