Hosts. Hyperparasitoids of Hemiptera : Coccidae via Hymenoptera : Encyrtidae longipenne ( Ashmead 1888: 17) (Mira)

Type. USNM

Distribution. N (Contra Costa, Marin, San Mateo, Santa Barbara, Sonoma, Tehama )

Host/habitat. Hyperparasitoid of Coccus hesperidum , Eulecanium sp. via Metaphycus flavus and Microterys nietneri ; NEW: Saissetia coffeae (UCRC)

Remarks. Gordh (1979) listed this species as E. longipennis . It is a Nearctic taxon, although Peck (1963) opined it might be a synonym of E. cornigerum ( Walker 1838) (a Palearctic species), thus resulting in a Holarctic distribution for the species. Annecke (1967) accepted this synonymy (without formalizing it), but other authors have not, and treat them as two separate species. A series of specimens (UCRC) is recorded from “ Aphycus sp. in Coccus hesperidum ”, but the host is undoubtedly a Metaphycus species.
