簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 18 - 19; 背鰭 (合計): 8-10; 肛門の骨 3; 臀鰭: 7 - 8. Diagnosis: The steeply sloped vomer, the small retrognathic jaw, and the presence of bicuspid teeth in the outer rows of both lower and upper jaws and enlarged conical teeth at the back of the jaws place this species in Tropheops (Ref. 119465). Tropheops biriwira, body depth 26.8-32.1% of standard length, cannot reliably be distinguished from other Tropheops on body depth, 23.6-34.5% (Ref. 119465). The breeding male of T. biriwira has green/light blue ground colouration with a green dorsal fin, while those of T. kumwera and T. kamtambo both have blue ground colouration and a blue dorsal fin; females of T. biriwira cannor reliably be distinguished from those of T. kumwera, but lack a black submarginal band in the dorsal fin that characterizes female T. kamtambo (Ref. 119465). There are fewer tooth rows, 2-5, on both upper and lower jaws in T. biriwira than in other species of Tropheops, 6-8, except in T. kumwera and T. kamtambo; Tropheops biriwira can be distinguished from T. kumwera and T. kamtambo by an on avreage larger eye, horizontal eye diameter 30.8-40.4% of head length and vertical eye diameter 29.6-35.4% of head length vs. 25.8-32.6% and 24.0-31.4% in T. kumwera and T. kamtambo, and also on average shorter snout, snout length 26.5-37.8% of head length vs. 28.0-42.8% in T. kumwera (Ref. 119465).
