Comments. In couplete 517 of TRJAPITZIN’ s (1989) key to Palaearcic genera he stated that in Aphydencyrtoides the frontovertex is 2× as long as wide. This statement is incorrect since in the type material the frontovertex is at most 1.3× as long as wide which would lead the user to Metablastothrix . Morphologically these two genera can be distinguished by the very short gonostyli and wide outer plates of the ovipiositor in Aphidencyrtoides which contrast with the relatively longer gonostyli and narrower outer plates of the ovipositor in Metablastothrix . Furthermore, the hosts of both genera belong to different superfamilies of hemipterans, the Aphidoidea and Coccoidea respectively ( SUGONJAEV & TRJAPITZIN 1988).
