🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 18; Anal spines: 0; Anal soft rays: 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 . 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% .
