Distribution. Throughout North America, west of the Mississippi River from British Columbia , Canada , south to central Mexico , and east to Oklahoma and Texas. Hosts. Aleyrodidae : unidentified species; Coccidae : Lecanium corni Bouché ; Diaspididae : Aonidiella aurantii (Maskell) , Chionaspis pinifolia (Fitch) , Diaspidiotus perniciosus (Comstock) , Diaspis echinocacti (Bouch é ), Diaspis manzanitae Whitney , Lepidosaphes beckii (Newman) , Mercetaspis halli (Green) , Parlatoria blanchardi TargioniTozzetti ; Phoenicoccidae: Phoenicoccus marlatti Cockerell ; Pseudococcidae : Ehrhornia cupressi (Ehrhorn) . Remarks. This is the most common species of Cybocephalus in western North America and is well represented in most North American collections. There seems to be a species cline between C. californicus and C. nigritulus along the Sierra Nevada mountain range. While the basal plate ( Fig. 53 ) of this phenotype bears some resemblance to that of C. nigritulus ( Fig. 109 ), the shape of the protibia ( Fig. 52 ) is clearly that of C. californicus ( Fig. 43 ), and the median lobe is indistinguishable from C. californicus . Therefore, this phenotype is considered to be C. californicus . For a full description of this species, see Smith and Cave (2006a) .
