Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); elucens: The specific name elucens is a Latin participial adjective meaning 'shining out' and is given with reference to the distinctive light blue subdistal band in the anal and caudal fins, contrasting and shining out of the overall dark colouration of body and fins of the males (Ref. 123810).

Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 16-18; Afterflossenstacheln 0; Afterflossenweichstrahlen: 17 - 19. Diagnosis: Nothobranchius elucens is distinguished from all other members of the genus by the following characters in males: body colouration golden-grey with brown scale margins creating irregular vertical stripes on trunk, anal fin yellow with brown spots proximally, with slender brown median band, followed by a slender light blue subdistal band and a slender black distal band; caudal fin brown proximally and medially, followed by a slender light blue subdistal band and a slender black distal band; dorsal fin golden with irregular brown blotches and stripes, with narrow light blue subdistal band and narrow black distal band (Ref. 123810). Furthermore, it differs from N. taiti by the morphometric characters of having a smaller head length of 29.5-33.1% of standard length vs. 35.0-38.6%, smaller prepectoral length of 31.2-33.9% of standard length vs. 34.2-38.6%, greater head depth of 81-87% of head length vs. 71-80%, greater interorbital width of 43-49% of head length vs. 31-40%, and greater caudal peduncle length of 145-152% of its depth vs. 134-143% (Ref. 123810).
Found in an isolated pool in a shallow depression on a floodplain (Ref. 123810). It is a micropredator, feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton (Ref. 123810). Nothobranchius elucens is recommended to be listed as vulnerable (Ref. 123810).
