Diagnosis

Clypeus with distinct lateral swellings, stronger in male than in female; scutellum convex, lateral carina extending to posterior impunctate area; ovipositor straight, 2.2–2.5 × as long as hind tibia.

Distribution

Previously known from India, Indonesia, Malaysia, Taiwan and Japan ( Gupta 1962; Yu et al. 2005; Amanda et al. 2011). This is the first record of this species from Vietnam ( Figure 8 ).

Remarks

Two subspecies are currently recognized: N. zebroides zebroides (Krieger) and N. zebroides indicus (Gupta) . The two subspecies differ only in the colour pattern: the nominate subspecies has rather black markings while N. zebroides indicus has rather ferruginous marks. Most of the Vietnamese specimens agree well with N. zebroides indicus except two male specimens from Quang Binh and Quang Tri provinces, which are closer to the nominate subspecies. As the differences between the two subspecies have not proved to be stable, we here synonymize the two names.
