Type locality. Reedley, Fresno Co., California, USA.

Material examined. USA. California, Tulare Co., Kingsburg, 19–24.ix.2005, 3–5.x.2005, and 11– 14.x.2005, G. Yokota (emerged from grape leaves infested with leafhopper eggs), numerous females and males in ethanol [ UCRC]. Colorado, Mesa Co., Palisade, Colo-Color Orchards, 621 37 1/4 Rd., 39°05’39’’N 108°21’43’’W, 1460 m: 29.viii.2006, S.V. Triapitsyn (emerged 3.viii–6.ix. 2006 in University of California, Riverside quarantine from Virginia creeper leaves infested with Erythroneura anfracta Beamer, S &R # 06– 28–02), 14 females, 6 males [ UCRC]; 4.ix.2007, S.V. Triapitsyn (emerged 7–14.ix. 2007 in University of California, Riverside quarantine from Virginia creeper leaves infested with Erythroneura anfracta Beamer, S &R # 07–39–02), numerous females and males in ethanol [ UCRC] and 1 female on a slide [ UCRC] (molecular voucher PR–08–193). Washington: Benton Co., near Prosser, Washington State University vineyard, 2.viii.2006 and 7.viii.2006, L. Wright (emerged from Vitis vinifera leaves infested with Erythroneura ? elegantula Osborn), 4 females and 6 males in ethanol [ UCRC]. Yakima Co., Sunnyside, Walsh Vineyard, 2.ix.1999, D.G. James (from eggs of Erythroneura sp. on cultivated grape), 1 female, 1 male on slides [ UCRC]. Also specimens listed by Triapitsyn (1998).

Female diagnosis. Antenna ( Figs 3 , 5 , 7 ) with F2–F5 subequal in length (F3 and F5 usually slightly shorter), F2 and F3 usually without mps (occasionally F3 has a mps on one antenna); basal one-third of forewing disc beyond venation with one well-defined, complete longitudinal row of setae in both sexes ( Figs 4 , 6 , 8 ); ovipositor 1.8–2.2x as long as protibia length; external plate of ovipositor usually with 2 distal setae (Triapitsyn 1998).

Hosts. Besides the leafhopper hosts indicated by Triapitsyn (1998) and Williams & Martinson (2000), recent host records of A. daanei include Erythroneura anfracta Beamer [new record] in Colorado, E. elegantula Osborn and E. ziczac Walsh in Washington ( Prischmann et al. 2007; Wright & James 2007), and E. ziczac in Okanagan Valley, British Columbia ( Lowery et al. 2007). Females of A. daanei [as Anagrus sp. 1 near A. daanei ] (from Palisade, Colorado) failed to parasitize fresh eggs of Homalodisca vitripennis (Germar) under quarantine laboratory conditions ( Morse & Stouthamer 2007).

Comments. Based on preliminary molecular data, Morse & Stouthamer (2007) identified separate forms from Colorado and Washington (referred to as Anagrus sp. 1 near A. daanei and Anagrus sp. 2 near A. daanei respectively) that were morphologically indistinguishable from specimens of A. daanei from California. However, the results of our expanded molecular analyses imply that these three forms likely fall within one, rather heterogenous species, A. daanei (see below).
