This species can be distinguished from Callopanchax monroviae by insertion of first dorsal fin ray slightly anterior to first anal fin ray versus a posterior insertion; it also has a dark red to black postopercular blotch above insertion of pectoral fin (Ref. 84062). Callopanchax sidibeorum can also be distinguished from males of C. occidentalis and C. toddi by up to three irregular and interrupted horizontal stripes on flanks, an absence of vertical dark red or reddish-brown stripes or broad blotches on sides and a mainly blue to blue-green body colour; females can be distinguished by mid-laterally blue to blue-green coloured scales and the absence of the dark brown vertical stripes or blotches, similar as in males (Ref. 84062).
