(UCRC),  Dysmicoccus timberlakei, hyperparasitoid of  Hyperaspis pleuralisvia  Homalotylus affinis(EMEC)   Remarks.The specimen (EMEC) reared from  D. timberlakeiis probably a hyperparasitoid of an undescribed species of  Pseudleptomastix,which was reared from the same host. This appears to be a species with a high variation in body color—ranging from coppery fuscous with yellow patches to almost totally dark, with the scutellum always at least partly yellow. A  Cheiloneurusspecies near  banksiwas collected from Inyo County (UCDC), and there is another long series from Los Angeles and Riverside counties (UCRC).    compressicornis(Ashmead 1894: 246) ( Chrysopophagus)    Type. USNM   Distribution.N (Los Angeles, Nevada, Orange, Riverside, San Bernardino, San Diego)  Host/habitat.Hyperparasitoid of undetermined Syrphidae,  Ceraeochrysa cubana,  C. sanchezi,  C. valida,  Chrysopa nigricornis,  Chrysoperla plorabunda,  C. rufilabris, via  Isodromus iceryae,  I. niger,  Gelis tenellus,  Perilampus chrysopae; NEW:  Chrysopa oculata, undetermined Hemerobiidae(both UCRC).   Remarks.Two  Cheiloneurusspecies near  compressicorniswere collected in Nevada & Sierra Counties (UCDC), another from Imperial County (UCRC), and two more specimens from Riverside County, which were reared from a whitefly on  Enceliasp. ( Asteraceae).  Chrysoperla carnea(Stephens)has been recorded as a host in North  America, but some authorities consider this species is restricted to the Palearctic, and would attribute such Nearctic host records to the  C. plorabundacomplex. The host record of a syrphid fly stems from a single observation by McGregor (1914)—it remains to be seen if this represents a misidentification, or if the secondary host range of  C. compressicornisdoes indeed extend beyond the Neuroptera(there are no records of  I. iceryae,  I. niger,  G. tenellusor  P. chrysopaeattacking any Diptera).     elegans(  Dalman 1820: 151)[ New state record](RLZC)    Type. NHRS   Distribution.W (Contra Costa, Marin, Stanislaus)  Host/habitat.Hyperparasitoid of  Mayetiola destructor(via  Platygaster zosinae),  Aclerda subterranea(via  Paraphaenodiscus subterraneus),  Eulecanium franconicum,  Phenacoccus hordei, Physokermes piceae,  Pulvinaria vitis,  Trionymus abberans   Remarks.In South  Americaand the Old World, this species is recorded as a hyperparasitoid of Aclerdidae, Pseudococcidaeand Coccidae, whereas in North  Americait is only known as a hyperparasitoid of Diptera, which suggests records of this species represents a complex of species or two biological races of one species ( Ferriere 1952). Neunenschwander et al.(1987)reported  Cheiloneurus?  elegansas a hyperparasitoid of  Phenacoccus manihotivia  Anagyrus lopeziin Africa, but this identification has apparently never been confirmed.  Eupelmus elegans Dalman 1820, is a junior of  C. elegans( Noyes 2001), which led Noyes (2001)to mistakenly record  Rhyacionia buolianaas a host of this species, based on the report of Millan de  DeSantis & DeSantis (1960). However, the host record in that paper referred to  Eupelmus elegans Blanchard 1942.     flaccus(  Walker 1847: 21) ( Encyrtus)    Type. BMNH   Distribution.N (Alpine, Contra Costa, Inyo, Marin, Monterey, Sacramento, Sonoma, Stanislaus)  Host/habitat.Hyperparasitoid of undetermined Cicadellidae;  Megamelus proserpinavia  Echthrodelphax fairchildii,  Haplogonatopus vitiensis,  Pseudogonatopus hospes   Remarks.This species was described from material collected in Ohio, and has become established in Hawaii.     inimicus  Compere 1925: 297    Type. USNM   Distribution.W (Alameda, Amador, Butte, Calaveras, Contra Costa, El Dorado, Los Angeles, Riverside, San Benito, San Bernardino, San Luis Obispo, Santa Barbara, Santa Clara, Stanislaus, Solano, Tulare, Ventura)  Host/habitat.Hyperparasitoid of  Ceroplastessp.,  Physokermes insignicola,  Saissetia oleaevia  Metaphycus lounsburyi,  M. physokermis; NEW:  Amonostherium lichtensioides,  Lecanodiaspis rufescens,  Pulvinaria mesembryanthemivia  Diversinervus elegans,  Microterys nietneri(all UCRC)   Remarks.Specimens of a  Cheiloneurusspecies near  inimicuswere collected from Fresno and Tehama counties (EMEC), Marin County (RLZC) and San Bernardino County, the latter having emerged from a gall on a  Quercussp. ( Fagaceae) (UCRC). McCoy & Selhime (1970)reported this species as a primary parasitoid of  S. oleaebased on the lack of host remains, but Rosen (1981)corrected this, pointing out that hyperparasitoids can consume their entire host.     lineascapus  Gahan 1910: 207    Type. USNM   Distribution.N (Los Angeles, Napa, San Bernardino, San Diego, Ventura)  Host/habitat.Hyperparasitoid of  Kermes nigropunctatus, Saissetia oleaevia  Metaphycus lounsburyi; NEW:  Radiococcus kelloggii(EMEC)   Remarks.The host record of a  Kermessp. on lilac ( Oleaceae) given in the original description is probably a misidentification, since as far as is known,  Kermesspp. are restricted to  Quercusspp.     noxius  Compere 1925: 302    Type. USNM   Distribution.C (Contra Costa, Los Angeles, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, Stanislaus)  Host/habitat.Hyperparasitoid of  Coccus hesperidum,  Saissetia coffeae,  S. oleaevia  Diversinervus elegans,  Metaphycus lounsburyi,  M. luteolus,  M. stanleyi,  Microterys nietneri   Remarks.This species was accidentally established in Hawaii ( Beardsley 1976). In nature, this species is probably restricted to  S. oleae/ M. lounsburyi—all other host records are from laboratory rearings. Weseloh (1969)reported this species appears to be able to discriminate between encyrtid and aphelinid primary parasitoids in the scale host. spp.  Remarks.In addition to the species listed above, I have seen specimens that appear to represent an additional 10 morphospecies present in the state
