Nothobranchius bellemansi and Nothobranchius occultus (Cyprinodontiformes: Nothobranchiidae) two new annual killifish from Sudan.

Valdesalici, S. 

Abstract: Two new species of annual killifish, Nothobranchius bellemansi and Nothobranchius occultus, are described from specimens collected in seasonal waters of southern Kordofan State in Sudan. Males Nothobranchius bellemansi are similar to Nothobranchius rubroreticulatus by presence of a broad light blue submarginal stripe and black marginal stripe on unpaired fins, but are distinguished by a deeper body, shorter head and by having the median portion of unpaired fins spotted, females are separated by a pattern of very small red spots on unpaired fins. Nothobranchius occultus is considered to be closely related to N. virgatus due to similarities in head profile, snout ventral profile and pelvic fin shape, and is distinguished from all other congeners by males with long pelvic fins and completely dark red brown body and fins in preserved specimens. Additionally a lectotype for Nothobranchius rubroreticulatus is designated.
