Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); nikiforovi: The specific name is given in honour of Andrei Nikiforov, from Russia, who participated in several field surveys aimed at research on Nothobranchius fishes in Tanzania, and he is co-discoverer of this new species and co-collector of the type specimens; a noun in genitive (Ref. 123990).
Eponymy: Andrei Nikiforov is a Russian killifish enthusiast who participated in several field surveys aimed at research on Nothobranchius species in Tanzania, and co-discovered and co-collected the type specimens of this one. (Ref. 128868), visit book page.

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 13 - 16; Épines anales: 0; Rayons mous anaux: 13 - 16. Diagnosis: Nothobranchius nikiforovi is distinguished from all other congeners, except N. eggersi, by males presenting two phenotypes; the blue phenotype having a bright iridescent light blue to blue-green body, with narrow red-brown scale margins creating irregular reticulated pattern forming chevron-shaped crossbars on posteroventral portion of body and median fins light blue with red-brown dotted pattern; the red phenotype has a dark red head, light blue dorsal and anal fins proximally and medially, dark red distally, with dark red stripes parallel to the fin rays, and plain dark red caudal fin (Ref. 123990). It differs from N. eggersi by male colour pattern: the blue phenotypes having median fins with dark grey distal portion, some of the rays of dorsal and anal fins with white tips only, vs. median fins light blue with distinct slender white distal band; the caudal fin lacking a spotted pattern, vs. dots arranged into irregular curved stripes; the red phenotype has a golden stripe between the nape and dorsal-fin origin, vs. light blue stripe; the dorsal and anal fin distal portion plain red and without light distal band, vs. with distinct narrow white distal band; the pelvic fin without distal band, vs. with distinct slender light blue to white distal band; furthermore, it differs from N. eggersi by the morphometric characters of having greater postorbital length of 49-55% of head length, vs. 42-48%, and greater head width of 64-71% of its depth, vs. 56-62% (Ref. 123990).
The species meets criteria B1ab(iii) for Vulnerable as conservation status; the increasing pressure on land and water resources of wetlands will continue to result in habitat degradation and represent an important threat to the species, raising vulnerability in terms of conservation status (Ref? 123990).
