Subgenus Parachelonus Tobias, 1995
Diagnosis. Body large-sized, at least 5.0 mm; head transverse; antennomeres of both sexes more than 20, rarely less; eye densely setose; frons and vertex striate-rugose; face flat, transverse to irregular punctate-rugose; clypeus often finely punctate, shiny; mesoscutum and scutellum evenly convex, punctate to alveolate-rugose; propodeum coarsely rugose; vein 1-SR+M of fore wing absent; hind coxa, femur and apex of tibia comparatively robust; metasomal carapace of male with deep apical opening, carapace apically usually rounded in dorsal view, rarely narrowed posteriorly.
Biology. Parasitoids of Sesiidae and Tortricidae ( Yu et al. 2016) .
Distribution. Palaearctic and Oriental regions ( Yu et al. 2016).
