, holotype female. (1) Wings; (2) outer hind claw; (3, 13) head, dorsal aspect; (4) mesosoma, dorsal aspect; (5) hind leg; (6) head, anterior aspect; (7) first metasomal tergite, dorsal aspect; (8) antenna; (9) habitus, lateral aspect; (10) hind tibial spurs; (11, 12) Detail of vein 1r-m and surrounding veins of hind wing. Magnification of scale line: 1.0× for 1, 5, 8, 9; 5.0× for 2; 1.5× for 3, 4, 6, 7, 10, 13; and 2.6× for 11, 12.
Diagnosis
Antenna longer than forewing. Terminal flagellomere strongly acuminate. Maxillary and labial palpi of female slender. Face wide. Occipital carina complete dorsally (but narrowly interrupted in
V. herberti
sp. nov.
) and ventrally; ventrally strongly and more or less perpendicularly curved to join hypostomal carina. Tarsal claws with pointed basal lobes. Dorsal carinae of first metasomal tergite remain separated and second tergite has indistinct mediobasal area. Hind wing with vein SR tubular until beyond hamuli, very strongly curved such that at most extreme it almost reaches wing margin, where there is usually a distinct inclivous fold representing cross-vein r; vein 2-SC+R swollen; vein r-m strongly curved.

can be recognized from other genera of

2. Head strongly protuberant in dorsal view; mediolongitudinal carina of propodeum present anteriorly; vein 2-SC+R of hind wing hardly widened; hind femur slender; pronotum coriaceous ventrally; marginal cell of hind wing near hamuli wider than apically; vein 1r-m of hind wing oblique and straight; Oriental...........................................
