توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 15 - 17; شعاع نرم باله پشتي (کل) : 7 - 10; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 7 - 9; مهره ها: 28 - 31. Diagnosis: Haplochromis pharyngalis differs from all species from the Lake Edward system, except Haplochromis fuscus, by a rounded caudal fin; very small, round and depply embedded chest scales, 7-11 pectoral-pelvic scales; small nape scales, and dominant males with white-blue first ray of pelvic fins (Ref. 128436). It differs from H. fuscus by an acute vs. blunt snout with a more shallow inclination, 40°-45° vs. 45°-60°; rounded vs. nearly squared dental arcades; and fewer rowsof inner oral teeth, 2-3, rarely 4, vs. 4-5 (Ref. 128436). It shares with H. elegans and H. aeneocolor a generalised Haplochromis morphology; it differs from both by 3-5 vs. 2-3 infraorbital chekk scales, deeper cheeks, 24.0-31.2% of head length vs. 19.2-23.8% and 20.1-24.4%, slightly smaller eyes, 26.9-33.1% of head length vs. 29.9-36.2% and 29.7-35.0%, and dominant males with green-yellow vs. blue and yellow flanks, respectively (Ref. 128436). Some specimens from Lake Edward share with Haplochromis mylodon, Haplochromis concilians, Haplochromis placodus and Haplochromis malacophagus an enlarged pharyngeal apparatus set with molariform teeth; it differs from all by recurved vs. straight outer oral teeth and from H. mylodon and H. concilians by the colour pattern of dominant males with green-yellow vs. blue flanks and faint vs. well-defined nostril and interorbital stripes; the latter is also diagnostic in preserved specimens (Ref. 128436).
The stomachs of a small number of specimens which were examined contained both larval and emergent insects (Ref. 558). Specimens from Lake George insectivorous, those from Lake Edward both insectivorous and molluscivorous (Ref. 128436).
