Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); aureus: Specific name from Latin 'aureus', golden; referring to yellow chest, cheeks, and snout in dominant males and yellow pelvic fins in females (Ref. 128938).

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 14 - 16; Raios dorsais moles (total) : 8 - 10; Espinhos anais: 3; Raios anais moles: 8 - 10; Vértebras: 30 - 31. Diagnosis: Haplochromis aureus is a species with an acute snout; acutely pointed oral teeth; very broad interorbital area, interorbital width 56.8-66.6% of head width; very short predorsal distance, predorsal distance 31.7-34.4% of standard length; dominant males light blue with yellow snout, cheeks, and chest (Ref. 128938). Small specimens can be mistaken for Haplochromis pappenheimi or H. pelagicus, but differ from both by a deeper body, body depth 30.7-33.5% of standard length vs. 25.4-31.0%; longer upper jaw, upper jaw length 29.3-35.6% of head length vs. 26.5-29.4%; fewer gill rakers, 12-14 vs. 13-18 (Ref. 128938). It resembles H. mentatus in habitus and overlaps slightly in habitat (H. mentatus mostly restricted to littoral regions), differs by a shorter lower jaw, lower jaw length 41.1-46.4% of head length vs. 43.9-51.0%; more and smaller upper outer teeth, upper outer teeth 48-65 vs. 28-46, and dominant males light blue with yellow cheeks and chest vs. uniformly yellow-green with red flanks (Ref. 128938).
Body shape (shape guide): fusiform / normal.
Abundant in the upper water layers of deepwater regions (Ref. 128938). It feeds on chaoborids and winged ants; most probably an insectivorous species that catches aquatic and terrestrial insects from the water surface (Ref. 128938).
