Psyttalia cosyrae (Wilkinson, 1927)
Fischer (1987) later included this species in the Opius subgenus Psyttalia.
Psyttalia was subsequently elevated to generic rank by Wharton (1987).
The combination Psyttalia cosyrae (Wilkinson) was first used by Wharton (1989).
Under laboratory conditions, Psyttalia cosyrae is capable of producing viable, female offspring through several generations when hybridized with Psyttalia concolor.
At least some (and maybe most) of the material introduced to Hawaii in the 1930s and 1940s from East Africa under the names perproximus and phaeostigma was actually Psyttalia cosyrae (Wharton and Gilstrap 1983).
