Valdesalici, S. 2012. Nothobranchius kardashevi and
Nothobranchius ivanovae (Cyprinodontiformes:
Nothobranchiidae): two new annual killifishes from the Katuma
River drainage, western Tanzania. Aqua, Journal of Ichthyology and
Aquatic Biology, 18 (4): 192, Figs. 1-2.
Abstract:
Two new annual killifish species, Nothobranchius kardashevi, new
species, and N. ivanovae, new species, are described based on
specimens collected in ephemeral pools in the Katuma River
drainage system, western Tanzania. Nothobranchius kardashevi,
new species, belongs to the N. ugandensis species group and N.
ivanovae to the N. taeniopygus species group. Both are
distinguished from the respective other group members by a
diagnostic combination of male colouration and morphological
characters.
