Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); flagrans: The species epithet flagrans is a Latin participial adjective meaning flaming, blazing, burning, glowing and is given with reference to the vivid orange-red colour of the submarginal bands of the anal and caudal fins in males (Ref. 98826).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 16 - 18; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 16 - 19. Diagnosis: Nothobranchius flagrans belongs to the N. brieni species-group, presenting the diagnostic characters in male colouration for this complex of the caudal and anal fins proximal portion spotted, distal part with light margin or light submarginal band and dark margin; absence of a dark distal margin on the dorsal fin; absence of spots on head; and absence of black posterior margin of scales (Ref. 98826). Nothobranchius flagrans is distinguished from all other species of this complex, with the exception of N. hassoni, by having the anal and caudal fins with broad orange-red submarginal band (Ref. 98826). It is, however, further distinguished from N. hassoni by having a dorsal fin with a light blue distal margin vs. absent; and anal and caudal fins with dark grey distinct margin vs. red-brown (Ref. 98826). Furthermore, within the N. brieni species-group, N. flagrans is characterised by the following unique combination of morphometric characters: prepelvic length 49.5-52.6% of standard length; head depth 86-92% of head length; and caudal peduncle length 151-161% of its depth (Ref. 98826).
