Vojtechirogas Quicke & van Achterberg gen. nov.

( Figures 1–13 , 26–29 )

Type species

Vojtechirogas novotnyi sp. nov. Gender masculine. Additional species: V. heberti sp. nov.; V. wantok sp. nov.

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.

Notes

Vojtechirogas gen. nov. can be recognized from other genera of Rogadinae with a sclerotized and more or less curved vein SR1 of hind wing as follows:

1. Tarsal claws pectinate; marginal cell of hind wing strongly widened apically; second metasomal tergite finely sculptured; eyes and ocelli strongly enlarged; Afrotropical............................. Scoporogas van Achterberg, 1991

The biology is unknown.

– Tarsal claws without pecten ( Figures 2 , 22 ); marginal cell of hind wing subparallel-sided apically ( Figures 1 , 14 ); second tergite coarsely sculptured, often costate (Figures, 20); eyes and ocelli less developed ( Figures 3, 6 , 17, 21 ); Indo-Australian......................................................... 2

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........................................... Rhogasella Baker, 1917

The biology is unknown.

– Head hardly protuberant in dorsal view ( Figures 3 , 21 ); mediolongitudinal carina of propodeum absent anteriorly ( Figures 4 , 19 ); vein 2-SC+R of hind wing more or less widened ( Figures 11, 12 , 25 ); hind femur moderately robust ( Figures 5 , 18 ); pronotum smooth ventrally ( Figures 9 , 24 ); marginal cell of hind wing near hamuli narrower than apically ( Figures 1 , 14 ); vein 1r-m of hind wing slightly curved or vertical ( Figures 11, 12 , 25 )................... 3

3. Episternal scrobe long and reaching precoxal sulcus ( Figure 9 ); tarsal claws with a large lobe ( Figure 2 ); basal 0.1 of vein SR of hind wing sclerotized ( Figure 1 ); basal half of vein 2-M of hind wing unsclerotized ( Figure 1 ); vein 1r-m of hind wing slightly curved and oblique ( Figures 11, 12 ); dorsal carinae of first metasomal tergite remain separated ( Figures 7 , 26–29 ); second metasomal tergite without a distinct triangular area mediobasally ( Figure 7 ); Papua New Guinea........................................ Vojtechirogas gen. nov.

Parasitoid mainly of Philiris helena (Lycaenidae) on Macaranga spp.

– Episternal scrobe short and remaining far from precoxal sulcus ( Figure 24 ); tarsal claws without lobe ( Figure 22 ); basal 0.4 of vein SR of hind wing sclerotized ( Figure 14 ); basal half of vein 2-M of hind wing sclerotized ( Figure 14 ); vein 1r-m of hind wing straight and vertical ( Figure 14 ); dorsal carinae of first tergite united ( Figure 20 ); second tergite with a distinct mediobasal triangular area ( Figure 20 ); Papua New Guinea........ Trigonophatnus Cameron, 1907

Parasitoid of Lycaenidae .
