Valdesalici, S. 2014. Nothobranchius bellemansi and
Nothobranchius occultus (Cyprinodontiformes: Nothobranchiidae)
two new annual killifish from Sudan. Killi-Data Series, 2014: 4–19.
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.
