Acanthaegilopsis malagasy gen. n. and sp. n. of Anacharitinae (Hymenoptera: Cynipoidea: Figitidae) from Madagascar and the Comoros

摘要

A new genus of the subfamily Anacharitinae (Hymenoptera: Figitidae), Acanthaegilopsis gen. n., from Comoros and Madagascar is described. Diagnostic characters of the new genus are illustrated and discussed. The Anacharitinae are a subfamily of Figitidae which can be easily distinguished from the rest of the family by some shared characteristics (Ros-Farre et al. 2000): triangular-shaped head in frontal view, rounded and continuous pronotal plate, and small broadly overlapping mandibles. The subfamilycurrently includes eight described genera: Acanthaegilips Ashmead, 1897; Aegilips Haliday, 1835; Anacharis Dalman, 1823; Calofigites Kieffer, 1909; Hexacharis Kieffer, 1907; Proanackaris Kovalev, 1996; Solenofigites Diaz, 1979; and Xyalaspis Hartig, 1843; together comprising 74 valid species. Although some anacharitines have been cited (Ronquist 1999) as parasitoids of aphid-feeding larvae belonging to the families Hemerobiidae and Chrysopidae (Neuroptera), their biology remains widely unknown.
