Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); planus: Specific name from Latin planus, flat, referring to its flat, shovel-like lower jaw (Ref. 126074).

Dorsale stekels (totaal): 14 - 16; Dorsale zachte stralen (totaal): 9-10; Anale stekels 3; Anale zachte stralen: 8 - 9; Wervels: 20 - 21. Diagnosis: Haplochromis planus differs from all other species of Haplochromis, except H. retrodens from Lake Victoria, by a shallow, broad and rectangular lower jaw with ascending arms steeply sloping upwards, enlarged and distinctly visible intrabuccally; oral-tooth bands U-shaped and, in large specimens of more than 75 mm standard length, set posteriorly with large and stout inner and outer teeth, especially in upper jaw; all oral mucosa in lower jaw at same height and oral-breathing valves strongly reduced to narrow, rectangular skin folds (Ref. 126074). It differs from H. retrodens by larger eyes, 35.7-41.6% of head length vs. 23.8-29.6%, correlated shorter snout, 24.6-28.8% of head length vs. 29.0-36.8%, and more slender interorbital width, 19.1-22.1% of head length vs. 24.2-33.8%, and dominant males with scarlet to red vs. dark grey-green flanks (Ref. 126074). It differs from H. concillans and H. erutus by a shallow vs. deep lower jaw, a narrower interorbital region, 19.1-22.1% of head length vs. 22.5-26.4% and 23.4-27.2% respectively, and dominant males with scarlet to red vs. blue-silver and silver-beige flanks, respectively; it differs further from H. concillans by a longer premaxillary pedicel, 21.9-24.4% of head length vs. 16.1-21.6%, and from H. erutus by a longer upper jaw, 27.6-32.1% of head length vs. 20.9-26.0% (Ref. 126074).
