Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); relictidens: Specific name of Haplochromis relictidens derived from the Latin 'relinquere', to relinquish, and 'dens', tooth and used in apposition; it refers to the decrease in number of outer teeth in both jaws with size (Ref. 127594).

Espinhos dorsais (total) : 15 - 16; Raios dorsais moles (total) : 7 - 10; Espinhos anais: 3; Raios anais moles: 8 - 9; Vértebras: 29. Diagnosis: Haplochromis relictidens differs from all other known species from the Lake Edward system by its unique lower jaw morphology in large specimens of more than 90 mm standard length, with lower jaw acute and upper jaw rounded, rendering anterolateral parts of upper jaw visible in ventral view; outer teeth very small, blunt to rounded, widely and irregularly set, few (16-26 vs. 22-65), and decreasing in number with size (Ref. 127594). It differs further from H. taurinus, H. molossus, and H. gracilifur by its more slender and acute lower jaw, 50.1-59.7% of lower jaw length vs. 51.4-72.7%, 67.0-87.0% and 61.9-69.4%, respectively; its larger lachrymal bones, 15.8-18.4% of head length vs. 11.5-16.4%, 13.3-17.0% and 13.7-14.3%, respectively (Ref. 127594). It is further distinct from H. paradoxus by its broader head, 47.7-54.7% of head length vs. 41.7-51.2% (Ref. 127594). Mature males green-gold with bright red flanks and very faint vertical stripes vs. different colour pattern in all other paedophagous species (Ref. 127594).
This species has a paedophagous diet (Ref. 127594).
