Eusemion Dahlbom 1857 

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.
