背棘 (总数) : 16 - 18; 背的软条 (总数) : 7 - 9; 臀棘: 3; 臀鳍软条: 6 - 7. Diagnosis: A moderately gracile species, with rounded head and well-developed sexual dimorphism and dichromatism (Ref. 97630). It differs from Pelvicachromis drachenfelsi and P. taeniatus, by a male caudal fin colouration without black or white margins/submargins, vs. white margin and black submargin in upper half of fin in P. drachenfelsi and black margin with white to yellow submargin in loser half of fin in P. drachenfelsi and P. taeniatus; it differs from P. drachenfelsi in caudal peduncle being shorter than deep to as long as deep, vs. usually longer than deep (Ref. 97630). It differs from P. humilis, P. rubrolabiatus and P. signatus in absence of seven or eight dark, vertical bars on body, and in three tubular infraorbital bones vs. two; it differs from P. silviae in lesser body depth, being 30.4-37.3% of standard length vs. 37.-43.0%, shorter prepelvic distance, being 32.5-37.7% of standard length vs. 37.9-44.3%, greater preorbital distance, being 17.0-22.3% of head length vs. 16.3-17.3%, 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 in upper half of caudal fin; it differs from P. roloffi in greater caudal peduncle length, 12.1-15.4% of standard length vs. 9.4-12.2%, and higher number of pored scales of lateral line, 26-29 vs. 24-26; it differs from P. sacrimontis in shorter interorbital distance, 20.7-29.3% of head length vs. 29.4-45.3%; and it differs from P. pulcher in rows of dots in the central field and lower part of the male caudal fin vs. absence (Ref. 97630).
