Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); latifrons: Specific name from Latin 'latus' for 'wide' and 'frons' for 'forehead'; referring to very broad interorbital area for a piscivorous species (Ref. 126312).

背面の脊椎 (合計) : 15 - 16; 背鰭 (合計) : 9 - 10; 肛門の骨: 3; 臀鰭: 7 - 8; 脊つい: 30. Diagnosis: Species with a piscivorous morphology; body very shallow, its body depth 27.2-30.1% of standard length; interorbital area flat and broad, interorbital width 57.4-63.3% of head width; outer oral teeth few and large, number of upper outer teeth 24-42; females green dorsally, white ventrally, and with a well-defined mid-lateral band; dominant male colour pattern unknown (Ref. 126312). Amongst piscivorous species from the Lake Edward system, Haplochromis latifrons differs from all, except H. mentatus and H. kimondo, by the combination of a broader interorbital area, interorbital width 57.4-63.3% of head width vs. 39.3-57.1%; a shorter anal fin base, anal fin base 14.7-17.3% of standard length vs. 17.1-22.2%; and a smallernumber of branched anal-fin rays, 7-8 vs. 9-11, rarely 8 (Ref. 126312). It differs from H. mentatus by the combination of a shorter dorsal-fin base, dorsal-fin base 47.2-50.1% of standard length vs. 50.3-54.2%; a strongly vs. weakly prominent premaxillary pedicel; a gentler sloping lower jaw side, 25-30° vs. 30-45°; juveniles and females green dorsally and white ventrally vs. uniformly yellow-green; and presence vs. absence of a well-defined mid-lateral band (Ref. 126312). It differs from H. kimondo by the combination of large vs. small outer oral teeth; a smaller number of outer upper jaw teeth, 24-42 vs. 43-70; and a shorter anal-fin base, anal-fin base 14.7-17.3% of standard length vs. 17.0-19.2% (Ref. 126312).
Based on its morphology, most probably a piscivorous species (Ref. 126312).
