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 View in CoL

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.

yolandae Compere 1926b: 39 View in CoL

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.
