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.
