पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 21-24; गुदा कांटा 0; ऐनल सौफट रेज़: 26 - 28. Diagnosis: Petrocephalus leo is distinguished from all other Petrocephalus species of central Africa by the following combination of characteristics: absence of electroreceptive rosettes on head, body colouration brownish with distinct black mark at the base of pectoral fin, but no subdorsal ovoid black mark; 21 to 24 branched dorsal-fin rays and 26 to 29 branched anal-fin rays (Ref. 113655). Absence of the three typical Petrocephalus electroreceptive rosettes on the head distinguish Petrocephalus leo from most of its congeners, except P. microphthalmus, P. haullevillii, P. schoutedeni and P. zakoni; but it can be easily distinguished from these species by its unique pattern of melanin markings: a distinct black spot at the origin of the pectoral fins but no subdorsal pigmentation mark (Ref. 113655). Petrocephalus leo can be further distinguished from P. zakoni by its slender body, body depth 2.9-3.4 times in standard length vs. 2.5-2.7 times in P. zakoni; its relatively shorter dorsal fin, dorsal fin length 4.4-5.0 times in standard length vs. 4.0-4.3 times; and its smaller eye, eye diameter 3.7-4.4 times in head length vs. 3.1-3.3 times (Ref. 113655). It can be further distinguished from P. microphthalmus, P. haullevillii and P. schoutedeni, by a higher dorsal-fin ray count, 21-24 vs. less than 20 in the other species (Ref. 113655).
