Annotated Checklist of California Encyrtidae (Hymenoptera) Zuparko, Robert L. Zootaxa 2015 4017 1 1 126 4LPP Timberlake 1926 Timberlake 1926 [151,505,1912,1938] Insecta Encyrtidae Gahaniella Animalia Hymenoptera 28 29 Arthropoda genus    Type. USNM   Distribution.W (Contra Costa, Los Angeles, Riverside, San Benito, San Diego, Stanislaus)  Host/habitat.  Alichtensia argentina,  Coccus hesperidum,  Eulecanium perinflatum,  Parthenolecanium corni, Saissetia coffeae, possibly as a hyperparasitoid   Remarks.Although Timberlake (1926)reared this species from  P. corni, no definitive biological studies of this species have been conducted. One congener,  G. tertia, is a hyperparasitoid of  Planococcus citrivia  Leptomastix dactylopii( Kerrich 1953), and a second,  G. saissetiae Timberlake, 1926, has been recorded from several families of scales ( Noyes 2001) and is suspected of being hyperparasitic on  Saissetia oleae( Compere 1939c), although Trjapitzin (2010)considered the entire genus was hyperparasitic.  DeSantis (1989)reported the host of  G. californicaas “Cochinilla blanda”: Noyes (2001)treated this host as a pseudococcid, but it is a common name for  C. hesperidum(see  DeSantis & Monetti 2008: 97).
