Nothobranchius flagrans, a new species of annual killifish from the
Lufira drainage, Democratic Republic of Congo
(Cyprinodontiformes: Nothobranchiidae). Ichthyol. Explor.
Freshwaters, 25 (3) (December 31.): 265, figs. 4-6.
Abstract:
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 .
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 . 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 . 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
