Xanthopimpla modesta (Smith, 1860)

Comparative diagnosis.

This species belongs to the Xanthopimpla stemmator species group sensu Townes and Chiu (1970). This species can be distinguished from other species of the group by the following combination of character states: dorsal part of occiput with black area (Fig. 3C ); mesoscutum without black mark in front of scutellum (Fig. 1F ) or, if present, black mark on median lobe with deep notch anteriorly; hind tibia with 12-18 pre-apical bristles (Fig. 5F ); propodeum and T I without black marks (Fig. 4F ); ovipositor sheath 1.1-1.2 × length of hind tibia.

Remarks.

This species is divided into two subspecies, X. modesta modesta (Smith, 1860) and X. modesta microcephala Krieger, 1914. All Japanese materials are identified as the former.
