Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); mentatus: Specific name probably derived from the Latin 'mentum' for 'chin'; probably referring to the protruding lower jaw (Ref. 126312).

Duri punggung (Keseluruhan (total)) : 15 - 16; duri punggung lunak (Keseluruhan (total)) : 9 - 10; Duri dubur: 3; Sirip dubur lunak: 8 - 9; vertebrata, bertulang belakang: 30 - 32. Diagnosis: Species with a piscivorous morphology; body shallow, body depth 29.0-32.3% of standard length; snout very acute in dorsal and lateral views; outer oral teeth few and large, number of upper outer teeth 28-46; vertebrae many, 30-32; dominant males yellow-green with a red anterior part of flank (Ref. 126312). Amongst piscivorous species from the Lake Edward system, Haplochromis mentatus differs from H. latifrons by the combination of a longer dorsal fin base, dorsal-fin base 50.3-54.2% of standard length vs. 47.2-50.1%; a weakly vs. strongly prominent premaxillary pedicel; a steeper sloping lower jaw side, 30-45° vs. 25-30°; and absence vs. presence of a well-defined mid-lateral band (Ref. 126312). It differs from H. rex and H. aquila by the combination of a longer caudal peduncle, caudal peduncle length 15.7-17.5% of standard length vs. 13.5-16.2%; a gentler sloping snout, 30-35° vs. 35-50°; and dominant males yellow-green with a red anterior part of flank vs. cream-coloured with an orange operculum, or light grey with a black head, respectively; further from H. rex by a lower number of infraorbital cheek scales, 3-4 vs. 5-6, rarely 4 or 7; further from H. aquila by smaller eyes, eye diameter 25.4-29.9% of head length vs. 30.0-31.5% (Ref. 126312). It differs from H. simba by the combination of a broader interorbital area, interorbital width 51.3-61.0% of head width vs. 45.5-50.4%; a larger number of outer upper jaw teeth, 28-46 vs. 22-31; absent to weakly prominent vs. strongly prominent premaxillary pedicel and mentum; and dominant males yellow-green with a red anterior part of flank vs. yellow with an orange anterior part of flank (Ref. 126312). It differs from H. glaucus by the combination of a longer caudal peduncle, caudal peduncle length 15.7-17.5% of standard length vs. 13.4-16.1%; a narrower lower pharyngeal bone, lower pharyngeal width 83.6-85.7% of lower pharyngeal length vs. 93.3-95.1%; a slightly shorter pre-pectoral distance, 33.1-38.2% of standard length vs. 36.4-39.4%; and dominant males yellow-green with a red anterior part of flank vs. uniformly blue (Ref. 126312). It differs from H. kimondo and H. quasimodo by the combination of a narrower head, head width 39.4-42.3% of head length vs. 42.0-48.1%; and dominant males yellow-green with a red anterior part of flank vs. grey dorsally and yellow or blue-black ventrally; further from H. kimondo by a very acute vs. blunt snout, and a gentler sloping snout, 30-35° vs. 40-50°; further from H. quasimodo by a shallower body, body depth 27.2-30.1% of standard length vs. 33.5-41.7% (Ref. 126312). It differs from H. falcatus by the combination of a shorter predorsal distance, 33.3-36.4% of standard length vs. 36.9-41.1%; a shorter head, head length 33.4-37.0% of standard length vs. 36.6-39.6%; straight to weakly recurved vs. strongly recurved outer oral teeth, a steeper lower jaw side, 30-45° vs. 15-25°; absence vs. presence of well-defined mid-lateral and dorsal-lateral bands (Ref. 126312). It differs from H. curvidens and H. pardus by the combination of a deeper lacrimal, 18.1-20.9% of head length vs. 16.0-18.3%; and smaller eyes, eye diameter 25.4-29.9% of headclength vs. 29.4-34.1%; further from H. pardus by dominant males yellow-green with a red anterior part of flank vs. speckled to uniformly black (Ref. 126312). It differs from H. squamipinnis by the combination of large vs. small outer oral teeth and a smaller number of outer upper jaw teeth, 28-46 vs. 46-71; a shallower body, body depth 29.0-32.3% of standard length vs. 32.4-39.3%; absence vs. presence of minute scales on proximal part of dorsal fin; and dominant males yellow-green with a red anterior part of flank vs. uniformly slate blue (Ref. 126312).
