Only four other species of &lt;em&gt;Petrocephalus&lt;/em&gt; lack all electroreceptive rosettes: &lt;em&gt;Petrocephalus microphthalmus&lt;/em&gt;, &lt;em&gt;Petrocephalus haullevillii&lt;/em&gt;, &lt;em&gt;Petrocephalus schoutedeni&lt;/em&gt;, and &lt;em&gt;Petrocephalus zakoni&lt;/em&gt;. &lt;em&gt;Petrocephalus leo&lt;/em&gt; sp. nov. can be distinguished from these four species in having a distinctive black mark at the base of the pectoral fins (versus absent in &lt;em&gt;P. microphthalmus&lt;/em&gt;, &lt;em&gt;P. haullevillii&lt;/em&gt; and &lt;em&gt;P. schoutedeni&lt;/em&gt;) and no subdorsal black mark (versus present in &lt;em&gt;P. zakoni&lt;/em&gt;). A phylogenetic analysis using mitochondrial cytochrome b gene sequences shows haplotypes of &lt;em&gt;P. leo&lt;/em&gt; sp. nov. are distinct, but are unexpectedly nested within &lt;em&gt;P. zakoni&lt;/em&gt; haplotypes, making this latter species paraphyletic. To investigate this conflict between morphology and mitochondrial cytochrome b, a nuclear marker, the first intron of the gene coding for the S7 ribosomal protein, was sequenced. The presence of four diagnostic indels between &lt;em&gt;P. zakoni&lt;/em&gt; and &lt;em&gt;P. leo&lt;/em&gt; sp. nov. sequences supports the reciprocal monophyly of these two species. This is the first reported case of conflict between morphology and mitochondrial phylogeny within the genus&lt;em&gt; Petrocephalus&lt;/em&gt;. Finally, three species of Petrocephalus are reported for the first time from the Oubangui region bringing the total of &lt;em&gt;Petrocephalus&lt;/em&gt; species in this region to 12.&lt;/p&gt;
