Remarks

Nineteen specimens of T. vassiliewi and 22 specimens of T. simoni in the NHMW bear USNMENT labels, including one with host material (USNMENT01059034). The paralectotype of T. vassiliewi is missing its antennae and metasoma. The paratypes of M. schimitscheki ( Fig. 4 ) are mounted on two cards on the same pin. The bottom specimen has no metasoma. We were able to identify the paratypes of M. schimitscheki as conspecific with T. scutellaris based on the presence of setation in the posteroventral portion of the metapleuron ( Fig. 4B ), the foveate forms of the mesoscutal humeral and mesoscutal suprahumeral sulci ( Fig. 4B ) and the vertex without a median depression ( Fig. 4C ). The holotype of M. schimitscheki was reared from the same egg mass as the paratype series, and its description is consistent with the morphology of the specimens examined, leading us to consider examination of these paratypes to be sufficient for making the synonymy.
