Oreochromis lepidurus

ΑγγλικάDiagnosis: mature male with tuberculate genital papilla, some of the tubercles prolonged into filaments (Ref. 2). Caudal fin of adults densely scaled, usually with a reticulate melanin pattern (Ref. 2, 55074). 28 vertebrae; total dorsal rays 24-27; 19-24 lower gill-rakers; in adults snout long, preorbital bone deep and blade of lower pharyngeal 2-2.3 times the median length of the toothed area; outer teeth of jaws bicuspid unless by wearing down of minor cusp; maternal mouthbrooder (Ref. 2). Description: body shape ovoid (Ref. 52307). Head profile steep (Ref. 52307) but straight, sometimes slightly convex (Ref. 55074). Snout relatively long (Ref. 52307), broader than long, as long as or a little shorter than postocular part of head (Ref. 2989), with convex upper profile (Ref. 1870, 1879, 2989). Mouth rather small (Ref. 2989). Maxillary extending to between nostril and eye (Ref. 1870, 1879, 2989, 53262, 55074). Teeth with slender shafts, the outer spoon-shaped with a small minor cusp that may be worn down; inner teeth tricuspid with subequal cusps; tooth bands of 4 rows, widening to 5 at the sides of the lower jaw (Ref. 2). Scales on cheek in 2 or usually 3 rows (Ref. 2, 1870, 1879, 2989), width of scaly part less than diameter of eye (Ref. 2989). Eye equal to or a little less than preorbital depth (Ref. 2989). Lateral apophyses of lower pharyngeal bone extending behind the toothed area, which is heart-shaped, including a broad area of dark-brown-tipped very slender teeth; 5 scales between bases of pectoral and pelvic fins (Ref. 2). Opercular scales large (Ref. 1870, 1879, 53262). Gill-rakers short; scales cycloid (Ref. 1870, 2989, 53262). 17-21 scales in upper part of lateral line, 11-13 in lower part (Ref. 2989). Last dorsal fin spine longest; third anal fin spine nearly as long as last dorsal fin spine (Ref. 1870, 1879, 2989). Dorsal fin almost reaching base of caudal fin in juveniles anterior third of caudal fin in adults; anal fin reaching as far as dorsal fin (
