Spathius Nees

Belokobylskij, Sergey A. & Kula, Robert R., 2012, Review of the brachypterous, micropterous, and apterous Braconidae of the cyclostome lineage (Hymenoptera: Ichneumonoidea) from the Palearctic Region 3240, Zootaxa 3240 (1), pp. 1-62 : 11

Genus Spathius Nees

Spathius , the most species-rich genus in Doryctinae , contains about 309 described species ( Yu et al. 2005). Only 21 species have been reported from the New World ( Deyrup 1979; Marsh 2002; Marsh & Strazanac 2009); about two thirds of the Old World species occur in the Oriental Region. Species are morphologically heterogeneous, but the genus was recovered as monophyletic in Zaldivar-Riverón et al. (2008a). Seven species exhibit wing size reduction ( Yu et al. 2005, Austin & Jennings 2009). Three of those (all apterous) are known from the Palearctic Region. All three occur exclusively in the West Palearctic, mainly Europe ( Belokobylskij 2003; Yu et al. 2005).
