Genus Neotrogaspidia Lelej, 1996

( Figs 48–49 )

Neotrogaspidia Lelej, 1996a: 20 , ♂ ♀.

Type species: Mutilla pustulata Smith, 1873 , by original designation.

Diagnosis. MALE. Hypostomal carina without denticle. Mandible without subbasal inner denticle; ventral margin excised into large basal tooth. Scape with a pair of longitudinal carina developed only apically. F1 compressed. Scutellum weakly convex with median smooth line. Meso- and metacoxa evenly convex with sparse long recumbent setae. T1 wider than long; S2 evenly convex without lateral felt line; S8 with strong lateral carina. Volsellar digitus straight, large, rod-like; penis valves weakly asymmetrical. FEMALE. Mesosoma divergent posteriorly, widest at propodeum; scutellar scale present. T2 with two basal spots of pale setae but without apical fringe or band of pale setae; T3 with complete or medially interrupted band of pale setae; T6 with distinct flattened pygidial area; surface of pygidial area irregularly rugose in basal half and unsculptured in apical half, or granulate throughout.

Distribution. Palaearctic and Oriental regions (Lelej 2007).

Comparison. The female of this genus is similar to that of Eotrogaspidia in having the mesosoma widest at the propodeum and the pygidial area irregularly rugose in the basal half, but differs in having the distance between the setal spots on T2 1.0–2.0 × spot diameter (0.3 × spot diameter in Eotrogaspidia ).

Remarks. Only one species, Neotrogaspidia pustulata ( Smith, 1873) is known from Japan.
