Achrysocharoides Girault, 1913

  A. parva, female
















Fore wing with submarginal vein (SMV) with 2 setae dorsally. Postmarginal vein (PMV) present and at most as long as stigmal vein (STV).
Antenna with funicle 3- and club 2- segmented in both sexes; sometimes, especially in male flagellum, it may be difficult to separate funicle from club. Male scape sometimes strongly inflated and with sensory pores placed at the ventral edge.
Head with large eyes. Fronto-facial suture distinctly separated from anterior ocellus and straight.
Pronotum without transverse carina. Notauli incomplete. Mesoscutum and scutellum strongly sculptured, sometimes with pits; mesoscutum without longitudinal groove; scutellum with a single pair of setae. Propodeum with median carina absent or restricted posteriorly, sometimes complete and strong, occasionally doubled (i.e. A. nitidus Hansson); plica occasionally present.
Petiole not distinct.
Coloration dark-green metallic.





Achrysocharoides is a moderate sized genus which mainly occurs in the Holarctic region; however, it is also known in the Australasian and Oriental fauna (Noyes, 2001).




Achrysocharoides species are known to be exclusively endoparasitoids of Lepidoptera leafminers and in particular of the families Gracillariidae and Nepticulidae (Noyes, 2001); however, Gates et al. (2002) have recently found A. ?zwoelferi (Delucchi) on Liriomyza sativae Blanchard (Agromyzidae).



Achrysocharoides belongs to the subfamily Entedoninae by having 2 setae on submarginal vein, scutellum with a single pair of setae, fronto-facial suture distinctly separated from anterior ocellus and male scape with sensory pores placed at the ventral edge.
This genus may be distinguished from the other Entedoninae included in the key by the combination of the following characters: postmarginal vein long at most as stigmal vein, fronto-facial suture straight and propodeum usually without median carina and plicae. Indeed, Achrysocharoides can be separated from Asecodes, Closterocerus and Trisecodes by not having row of setae extending from stigmal vein; from Apleurotropis, Pediobius, Proacrias and Pleurotroppospsis by not having transverse carina on pronotum and median carina on propodeum; moreover, Apleurotropis and Pleurotroppopsis have longitudinal grove posteriorly on mesoscutum and Pleurotroppopsis has also a pair of longitudinal lines on scutellum.
Keys to Achrysocharoides species are available for Britain (Bryan, 1980), Japan (Kamijo, 1990a) and North America (Yoshimoto, 1977; Kamijo, 1991). Moreover, Hansson (1983) revised the Swedish species.
