Morphology | Morphometrics
(total): 78 - 18;
soft rays: 7 - 8. Diagnosis: A moderately gracile species, with rounded head and well-developed sexual dimorphism and dichromatism (Ref. 97630). It differs from all congeners with the exception of Pelvicachromis taeniatus by a black margin with a white to pale bluish submargin in the lower half of the male caudal fin, vs. no margin/submargin in the other species, and it differs from all congeners in a white margin and a black submargin in the dorsal half of the male caudal fin, vs. not present (Ref. 97630). It differs in female colouration from P. taeniatus and P. kribensis in showing a dusky blackish margin and absence of horizontal dark bars in the caudal fin (Ref. 97630). It differs from P. taeniatus and P. kribensis in a caudal peduncle usually longer than deep, vs. shorter than deep to as long as deep; it differs from P. humilis, P. rubrolabiatus and P. signatus in the absence of seven-eight dark, vertical bars on body, and in three tubular infraorbital bones vs. two; it differs from P. silviae in a lesser body depth, 28.7-35.1% of standard length vs. 37.4-43.0%, longer caudal peduncle, the caudal peduncle length 93.9-124.6% of caudal peduncle depth vs. 73.2-85.3%, and more spines in dorsal fin, 17-18 vs. 14-16; it differs from P. subocellatus in males by absence of a lappet-like elongation of some rays of caudal fin; it differs from P. roloffi in greater caudal peduncle length, 12.4-18.2% of standard length vs. 9.4-12.2%, and higher number of pored scales of lateral line, 27-29 vs. 24-26; it differs from P. sacrimontis in shorter interorbital distance, 16.3-27.4% of head length vs. 29.4-45.3%; it differs from P. pulcher in rows of dots in the central field of the male caudal fin vs. absence (Ref. 97630).
This species is restricted to pure freshwater of low conductivity and pH (Ref. 97630).
