Psyllaephagus Ashmead 1900 

Hosts. Hemiptera  : Aphalaridae  , Psyllidae  , Triozidae 

bliteus Riek 1962: 722  Type. ANIC

Distribution. E (Central Valley, San Francisco Bay Area, Central Coastal area, southern California coastal and inland areas)

Host/habitat. Creiis costatus  , Glycaspis brimblecombei  , G. sp.

Remarks. This species was imported from Australia and released in California in a biocontrol program against Glycaspis brimblecombei  on Eucalyptus camaldulensis  ( Myrtaceae  ) in 2000 and immediately established ( Dahlsten et al. 2003; Daane et al. 2005). Further releases resulted in establishment throughout the Central Valley and coastal areas of central and southern California, with pest suppression more effective in the cooler, coastal areas ( Dahlsten et al. 2008). It appears to be a very vagile species, as I have collected it in two sites that appear to have no Eucalyptus  species in the immediate vicinity.

brachiatus Riek 1962: 726  [New state record]( RLZC)

Type. ANIC

Distribution. E (Alameda, Contra Costa)

Host/habitat. Cardiaspina fiscella  , Glycaspis  sp.

Remarks. I collected a single male that appeared referable to this species, from low roadside vegetation near a Eucalyptus camaldulensis  heavily infested with Glycaspis brimblecombei  in Oakland in June 2015. A month later, I found a number of males on several tree species at the peak of Mt. Diablo, about 27 kilometers east of the Oakland site. This species was never intentionally imported into California and presumably was accidentally introduced along with the tree and the psyllid, which, if proved, would be a new host record. This species is known only from males, but I collected a series of undetermined females from the E. camaldulensis  that I suspect are conspecific.

pachypsyllae ( Howard 1885: 15)  ( Encyrtus  )

Type. USNM

Distribution. N (Imperial, San Bernardino)

Host/habitat. Pachypsylla celtidisgemma  , P. celtidisvesicula  , P. venusta  , Trioza beameri 

parvus Riek 1962: 749 

Type. ANIC

Distribution. E (Orange, Riverside, San Bernardino, San Diego)

Host/habitat. Eucalyptolyma maideni  , Spondyliaspis  sp.

Remarks. This species had been imported from Australia in a biocontrol project against E. maideni  , but before it was released it was found to have already been adventitiously established ( Jones et al. 2011).

perplexus Riek 1962: 750 

Type. ANIC

Distribution. E (Orange, Riverside, San Bernardino, San Diego) Host/habitat. Cryptoneossa triangula  , Eucalyptolyma  sp. Remarks. Jones et al. (2011) reported this species (mistakenly as Psyllaephagus perplexans Cockerell  ) has established in California adventitiously.

pilosus Noyes 1988 b: 105 

Type. NZAC

Distribution. E (Contra Costa, Los Angeles, Monterey, Orange, San Diego, San Joaquin, San Luis Obispo, Santa Clara, San Mateo, Sacramento, Sonoma, Ventura)

Host/habitat. Ctenarytaina eucalypti  ; NEW: C. spatulata  ( UCDC)

Remarks. Imported from New Zealand and Australia in a biocontrol program against Ctenarytaina eucalypti  , this species was released in several sites in California in 1993, and immediately established ( Dahlsten et al. 1998).

spp.

Remarks. In addition those species listed above, I have seen specimens that appear to represent an additional 15 morphospecies present in the state ( CSCA, EMEC, RLZC, UCDC, UCFC, UCRC).
