وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 0; الأشعة الظهرية الناعمة (المجموع) : 10; شوكة شرجية: 0; أشعه شرجية لينه: 15 - 18; فقرات: 33 - 34. Diagnosis: Brycinus epuluensis is distinguished from all species belonging to the macrolepidotus group by having a short snout, more than 3 times in head length vs. less than 3 times, and fewer premaxillary teeth, 6-7 vs. 8-11; it is distinguished from all species belonging to the longipinnis group by the absence of a fronto-parietal fontanelle in adults vs. fronto-parietal fontanelle always present, fewer lateral line scales, 18-22 vs. 25-36, and generally fewer anal-fin rays, iii,12-15 vs. iii,14-25; it is distinguished from aal species of the nurse group by having 6 or exceptionally 7 premaxillary teeth vs. 8-10, exceptionally 7 (Ref. 113515). The species is most similar to Brycinus imberi, from which it is mainly distinguished by fewer premaxillary teeth, 6-7 vs. 7-8, fewer lateral line scales, 18-22 vs. 21-31, and the presence of a black mid-lateral band (Ref. 113515).
Body shape (shape guide): fusiform / normal.
