Hemiptera : Coccidae claripennis (Compere 1928: 216) ( Microterys ) Type . USNM Distribution. N (Alameda, Contra Costa, El Dorado, Kern, Lassen, Los Angeles, Modoc, Monterey, Napa, Riverside, San Bernardino, San Luis Obispo, Santa Clara, Shasta, Stanislaus, Yolo) Host/habitat. Eulecanium tiliae , Parthenolecanium corni , P . fletcheri, P . quercifex Remarks. This species has a Nearctic distribution, and is only reliably recorded from Coccidae ( Noyes 2001 ) . There is a single record of it from Brazil (de Santis 1980 : 195), which appears to be based on an earlier Brazilian catalog by Araújo e Silva et al. (1968) . However, in the earlier work M . claripennis was not recorded from Brazilunder Encyrtidae (pp. 599–600) they list only 5 described species, three of which are now placed under Tanaostigmatidae . Instead this species is simply cited (page 100, as Microterys claripennis ) as a parasitoid of Aetalion reticulatum (Linnaeus) ( Hemiptera : Aetalionidae ). In my opinion, this is a dubious host record (no other encyrtids have been recorded parasitizing this family, and only Prionomastix has been recorded as attacking the closely related Membracidae ). Sugonjaev & Trjapitzin (1988) opine that M . claripennis is actually a secondary parasitoid via Encyrtus fuscus , based on two lines of thought. The first is the incidence of hyperparasitism in closely related species, including the congeneric M . truncatipennis (Ferrière) ; however, the latter species has since been placed in the genus Blastothrix . The second is Compere’s unpublished notes from 1911–1912 , although they note that Compere (1928) later stated nothing was known of the status (i.e.: a primary or secondary parasitoid) of M . claripennis . Thus its status remains unknown. Undetermined specimens of this genus have also been collected from Lassen, Marin and Yolo counties (CSCA, EMEC).
