Prochiloneurus Silvestri 1915

Prochiloneurus Silvestri 1915

Hosts. Hyperparasitoid of Hemiptera: Pseudococcidae via Hymenoptera: Encyrtidae

dactylopii (Howard 1885: 17) (Chiloneurus) [new state record] (RLZC, UCRC)

Type. USNM

Distribution. W (Alameda, Contra Costa, Glenn, Imperial, Marin, Orange, Santa Clara, Stanislaus, Tulare, Ventura)

Host/habitat. Hyperparasitoid of Ferrisia virgata, Phenacoccus manihoti, P. solenopsis, P. sp., Planococcus citri, Pseudococcus comstocki, P. sp., Puto barberi via Anagyrus diversicornis, A. lopezi, Leptomastix dactylopii and Zarhopalus putophilus.

Remarks. De Santis (1980) reported Coccus viridis and Chrysopa sp. as hosts for this species, evidently based on Parker et al. (1953), but the latter paper simply reported that P. dactylopii was reared from a lot containing (principally) Coccus viridis and some Chrysopa cocoons—there is no conclusive evidence it emerged from either of these taxa. However, De Santis & Fidalgo (1994) reported a single female of this species had emerged from the pupa of a Sympherobius sp. (Neuroptera: Hemerobiidae) collected in Chile—a record which, in my opinion, needs to be confirmed. A specimen from Orange County (UCRC) was labeled as “working on C. citrophilus ” (probably = Pseudococcus calceolariae). Several specimens from Alameda, Contra Costa, Glenn, Imperial, Santa Barbara and Santa Clara counties appear to be intermediate between P. dactylopii and P. modestus (RLZC, UCDC).
