Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335); pulsivertens: The species name comes from the Latin 'pulsus', meaning impulse, beating; and from 'vertere', meaning to turn, exchange; the name describes the unusual EOD waveform of the species (Ref. 85331).

Diagnosis: Petrocephalus pulsivertens is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with at least 25 branched rays; anal fin with at least 31 branched rays; mouth large, the ratio head length and mouth width between 2.0 and 3.7; 15-21 teeth in the upper jaw; 24-30 teeth in the lower jaw; and eye large, the ratio head length and eye-diameter between 3,2 and 3,5 (Ref. 85331). Pigmentation pattern consists of two distinctive melanin markings (black patches): (1) a distinct ovoid mark below the anterior base of the dorsal fin; and (2) a crescent-like mark, sometimes diffuse, centered at the base of the caudal fin and extending onto the upper and lower parts of the caudal fin (Ref. 85331).
Body shape (shape guide): fusiform / normal.
The EOD waveform of Petrocephalus pulsivertens resembles an inverted-polarity version of the 'typical' Petrocephalus EOD (Ref. 85331).
