Etymology: Otopharynx: Greek, ous = hear + Greek, pharyngx = pharynx (Ref. 45335); alpha: From αλφα (alfa), first letter of the Greek alphabet; the suprapectoral spot and posterior stripe suggest a dot and dash, which represents "A" in International Morse Code; a noun in apposition (Ref. 119408).

背棘 (總數) : 17; 背的軟條 (總數) : 11 - 12; 臀棘: 3; 臀鰭軟條: 9 - 10. Diagnosis: A medium-sized laterally spotted haplochromine separable from all previously described species of Otopharynx both by its unique melanin pattern and by its distinctive lower pharyngeal bone (Ref. 119408). The suprapectoral spot is rectangular, 2-2.5 scales high, longitudinally elongate, covering 7-8 consecutive scales starting with the seventh scale of the upper lateral line, extending vertically from just above the lateral midline to slightly above the upper lateral line; the supraanal and precaudal spots are conjoined, forming a continuous stripe, paler at its midlength in some specimens, from the level of the anal-fin origin to the base of the caudal fin; the lower pharyngeal bone is broadly triangular, somewhat heart-shaped, with numerous uniformly small, laterally compressed, crowded, bicuspid teeth (Ref. 119408).
Body shape (shape guide): short and / or deep.
