Etymology: Otopharynx: Greek, ous = hear + Greek, pharyngx = pharynx (Ref. 45335); styrax: From the Greek masculine noun στύραξ (styrax), a metal spike at the lower end of a spear shaft, for the resemblance of this elongate cichlid with pointed head to the shape of that classical object; a noun in apposition (Ref. 119408).

Duri punggung (Keseluruhan (total)) : 16 - 17; duri punggung lunak (Keseluruhan (total)) : 12 - 14; Duri dubur: 3; Sirip dubur lunak: 9 - 10. Diagnosis: A medium-sized, laterally spotted haplochromine distinguishable from all previously described Otopharynx species by its more elongate body, its depth 24.3-28.6% of standard length; the next-most-elongate species are Otopharynx decorus, depth 29.4-33.3% of standard length, and O. lithobates, depth 29.5-34.4% of standard length; all others have a body depth larger than 31% (Ref. 119408). Otopharynx styrax is further separated from O. decorus by its longer caudal peduncle, length/depth 2.0-2.3 vs. 1.5-1.6 in O. decorus, and its narrower lower pharyngeal bone, the lateral edges of the horns diverging at about 70° vs. 79-87° in O. decorus; it is further distinguished from O. lithobates by the absence of dark spots on the dorsum below the dorsal-fin base vs. 4-6 distinct dorsal midline spots in O. lithobates, and longer caudal peduncle, length/depth 2.0-2.3 vs. 1.3-1.7 in O. lithobates (Ref. 119408).
Body shape (shape guide): fusiform / normal.
