🐟 Physical Description

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 8 - 9; Vertebrae: 29 - 31. Diagnosis: Haplochromis concilians differs from all species of Haplochromis by skin covering snout thickened and usually merged with upper lip, by which snout and lip form an uninterrupted surface and anterior outer teeth in lower jaw located distinctly buccaly, hereby leaving labialmost part of lower jaw edentulous . Within Lake Edward system, it shares with H. erutus, H. planus, H. eduardianus and H. labiatus short and stout jaws and large or more strongly developed lips; it differs from all by a shorter premaxillary pedical, 16.1-21.6% of head length vs. 21.4-24.0%, 21.924.4%, 21.8-26.4% and 24.0-27.6% respectively; and hypertrophied pharyngeal jaws set with molariform teeth vs. more slender jaws set with, at most, stout teeth . It further differs from H. erutus by straight and unicuspid outer teeth vs. recurved and bicuspid; from H. eduardianus by mostly prognathous vs. retrognathous jaws and straight and conical outer teeth vs. recurved and spoon-shaped; and from H. labiatus by a steeper head, 60°-75° vs. 40°-55°, mostly prognathous vs. iso- to retrognathous jaws and anteriormost outer teeth in lower jaw implanted upright vs. procumbent .
