Espinhos dorsais (total) : 13 - 15; Raios dorsais (total) : 10 - 12; Espinhos anais: 3; Raios anais : 9 - 11. Diagnosis: Hemichromis angolensis can be distinguished from H. fasciatus by the absence of small black dots between the first three dark stripes on the flanks of the body of adults in most populations of H. fasciatus; it can further be distinguished from H. fasciatus by a combination of overlapping morphometrics, mainly by a high number of anal fin soft rays, 9-11 vs. 8-10; a greater body depth, 30.3-42.4% of standard length vs. 27.1-37.8%; a greater head depth, 51.4-70.6% of head length vs. 48.4-66.0%; and shorter length of lower jaw, 35.4-45.7% of head length vs. 40.0-49.0% (Ref. 128620). Hemichromis angolensis can be distinguished from H. camerounensis by a combination of overlapping morphometrics, mainly by a greater prepelvic distance, 39.0-52.0% of standard length vs. 37.6-48.5%; a shorter length of anal fin base, 13.2-17.7% of standard length vs. 14.5-18.3%; and greater preorbital distance, 10.3-18.1% of head length vs. 9.1-13.2% (Ref. 128620). Hemichromis angolensis can be distinguished from H. elongatus by a combination of overlapping morphometrics, mainly by a shorter head length, 33.6-39.7% of standard length vs. 36.9-40.2%; a shorter length of anal fin base, 13.2-17.7% of standard length vs. 14.8-22.8%; greater eye orbit diameter, 19.8-31.0% of head length vs. 18.8-28.8%; and shorter length of lower jaw, 35.4-45.7% of head length vs. 38.9-46.2% (Ref. 128620).
