Remarks. Microterys nietneri is a widespread (perhaps even cosmopolitan) species, but it is not clear if it occurs naturally in California. Howard (1881) described Encyrtus flavus from Los Angeles County, but Timberlake (1913) and Bartlett & Lagace (1961) noted that this species was also known from Asia and opined it had been accidentally established here. In the1950s a “black scale race” of this species was introduced from India and Pakistan in a series of (apparently unsuccessful) biocontrol introductions ( Clausen 1959 ; Bartlett 1978a ). In 1989 , Trjapitzin synonymized E . flavus under M . nietneri . Bartlett & Lagace (1961) and Rosen & Kfir (1980) noted that several geographical strains of this species exist, and they differ in their host preferences. Noyes (2001) includes a host record of “ Coccus piperus ”, referred to Hayat’s (1986) catalog of Indian Encyrtidae , but in that work the host is properly spelled as “ Coccus piperis ” (now placed in the genus Maacoccus ). There are specimens reportedly reared from Aonidiella aurantii (UCRC), but this identification is questionable. physokermis Compere 1926b : 43 Type . USNM Distribution. C (Alameda, Calaveras, Contra Costa, Madera, Monterey, Napa, San Francisco, Santa Clara) Host/habitat. Physokermis insignicola Remarks. Noyes (2001) mistakenly recorded this species from Japan . sylvius ( Dalman 1820: 154 ) ( Encyrtus ) Type . NHRS Distribution. W (Calaveras, El Dorado, Inyo, Lassen, Los Angeles, Merced, Modoc, Napa, Plumas, Riverside, San Bernardino, San Diego, Yosemite National Park ) Host/habitat. Didesmococcus unifasciatus , Eulecanium ficiphilum (nec ficifilum ), E . nocivum , E . sericeum , E . tiliae , E . sp., Parthenolecanium corni , P . persicae , P. rufulum , Physokermes jezoensis , Rhodococcus perornatus , R . spiraeae , R . turanicus , Sphaerolecanium prunastri , Stotzia maxima Remarks. This is a Holarctic species that was originally recorded from California under the junior synonym M . titiani Girault (1917a) . xanthopsis Compere 1926b : 41 Type . USNM Distribution. N (Alameda, Amador, Calaveras, Contra Costa, Inyo, Kern, Los Angeles, Marin, Napa, Placer, Riverside, San Bernardino, San Francisco, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Solano, Stanislaus, Tulare, Yolo) Host/habitat. Parthenolecanium corni , P . persicae Remarks. Noyes (2001) mistakenly recorded this species from Japan . yolandae Compere 1926b : 39 Type . USNM Distribution. C (Alameda, Contra Costa, Riverside, San Benito, Solano, Tulare, Yolo) Host/habitat. Kermes cockerelli Remarks. Noyes (2001) mistakenly recorded this species from Japan . spp. Remarks. I have seen specimens that appear to represent an additional seven morphospecies present in the state (EMEC, LACM, RLZC, SBMN, UCFC, UCRC). One of these species had previously ( Dreistadt & Hagen, 1994 ) been reported as a parasitoid of Eriococcus spurius , and it is not clear if it is a native species or if it had been introduced into the state.
