Material examined

Ninh Binh, Cuc Phuong NP: 1♀ ( RMNH), 225 m a.s.l., 15 April to 1 May 2000, Malaise trap, Q. P. Mai leg. ; Dak Lak, Chu Yang Sin NP: 1♀ ( RMNH), 740 m a.s.l., 1–10 June 2007, Malaise trap, C. v. Achterberg and R. de Vries leg. ; Dong Nai, Cat Tien NP: 1♀ ( IEBR), 100 m a.s.l., 14–20 May 2007, Malaise trap, C. v. Achterberg and R. de Vries leg.

Diagnosis

Scutellum strongly convex, lateral carina extending to middle, plus median longitudinal carina present on anterior slope; epicnemial carina present on lower half; ovipositor straight, 1.1 × as long as hind tibia.

Distribution

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

Remarks

Gupta (1962) recognized four subspecies: N. scutellata scutellata from Malaysia and Singapore; N. scutellata davidi , N. scutellata marjoriae and N. scutellata samarensis from the Philippines. The Vietnamese specimens agree with the nominate subspecies, which differs from the other three in lacking a black mark at the level of the sternaulus, the epicnemial carina present only on the lower half of the mesopleuron, and the presence of a dorsolateral carina on the first tergite (distinct to the level of the spiracle). These differences seem significant and it seems probable that the Philippines subspecies represents a separate species. The specimen from Dak Lak Province has the lower mandibular tooth only slightly longer than the upper tooth in comparison with the specimens from Ninh Binh and Dong Nai provinces.
