توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 16 - 17; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 17 - 18; مهره ها: 29. Diagnosis: The colour pattern of Nothobranchius torgashevi males is compparable to that of other N. ugandensis group members, comprising light blue scales and a broad, irregular reticulated pattern on the body, vivid orange or red oblique bars on the head and dorsum, a yellow or blue anal fin, and large vivid red spots on the dorsal and anal fins; other shared characters include: head rounded with a slightly concave to nearly straight dorsal profile; predorsal region convex between the nape and posterior extremity of the dorsal fin base; cephalic squamation variable (Ref. 116436). Nothobranchius torgashevi can be distinguished from all other species in the N. ugandensis group by the following combination of characters: flank scales with red margins; caudal fin plain red; pectoral fin hyaline with a few proximal red dots; anal fin light blue with red dots proximally, yellow or creamy white distally; dorsal and anal fins with red margin; 16-17 dorsal fin rays; 17-18 anal fin rays; 31-33 scales in the median lateral series; 11-12 transverse scale rows; 16 circumpeduncular scales (Ref. 116436).
Found in a seasonal ditch, less than 1 m deep and without aquatic vegetation, the water light clay grey and turbid with a pH of 8.3 and temperature varying from 25 to 30°C (Ref. 116436).
