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 Australiaand released in California in a biocontrol program against  Glycaspis brimblecombeion  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  Eucalyptusspecies in the immediate vicinity.     brachiatus  Riek 1962: 726[ New state record](RLZC)    Type. ANIC   Distribution.E (Alameda, Contra Costa)  Host/habitat.  Cardiaspina fiscella,  Glycaspissp.   Remarks.I collected a single male that appeared referable to this species, from low roadside vegetation near a  Eucalyptus camaldulensisheavily infested with  Glycaspis brimblecombeiin 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. camaldulensisthat 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, Spondyliaspissp.   Remarks.This species had been imported from Australiain 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, Eucalyptolymasp. Remarks. Jones et al.(2011)reported this species (mistakenly as  Psyllaephagus perplexansCockerell) has established in California adventitiously.     pilosus  Noyes 1988b: 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 Zealandand Australiain 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).
