Holcotetrastichus Graham, 1987

Note.

This is a small genus erected by Graham (1987), with Cirrospilus rhosaces Walker, 1839 as the type species. Only two species have been described: Holcotetrastichus manaliensis Graham, 1991 and Holcotetrastichus rhosaces (Walker, 1839). It can be distinguished from other Tetrastichinae especially by the strong transverse costulae in deep broad sublateral grooves and the hypopygium reaching nearly the tip of the gaster (Graham 1987). The species are parasitoids of some species of Cassida ( Coleoptera, Chrysomelidae) (Graham 1991).
