Published online by Cambridge University Press: 31 May 2012
Extract
The genus Zaschisonyx Ashmead includes but a single nearctic species, Z. montana (Cresson), of which three forms are recognized in this paper. In all these forms the males are identical, as are also the saws of the females, so that only subspecific or varietal names can be given within the group.
