Genus Nazgulia Hedqvist, 1973

Nazgulia Hedqvist, 1973: 239-240. Type species Nazgulia petiolata Hedqvist, 1973, by original designation and monotypy.

Redescription.

Head without occipital carina. Gena without hollow at mouth corner; gena lamina absent. Lower margin of clypeus not protruding, emarginate in the middle; tentorial pits indistinct (Fig. 17 ). Antennal formula 11264; anelli small, F1 transverse and shorter than F2, F2 longer than broad, F3-F6 subquadrate, antennal clava not large, micropilosity area small and occupies the lower part of 2 last claval segments (Fig. 17 ). Antennal toruli situated on level of lower edges of eyes; antennal protuberance absent; scrobes shallow. Both mandibles with 4 teeth (Fig. 17 ).

Mesosoma moderately depressed (Figs 13 , 14 ). Pronotum narrower than mesoscutum; collar margin not carinate. Notauli complete (Fig. 16 ). Scutellum depressed, without conspicuous sublateral grooves, with distinct reticulate frenal area and shallow frenal groove (Fig. 16 ). Metapleuron entirely reticulate (Fig. 14 ). Propodeum with weak plicae; costula and median carina absent; nucha subglobose and reticulate; propodeal spiracles near to front margin of sclerite (Fig. 16 ). Prepectus distinct triangular, longer than tegula. Fore wing hyaline, with speculum; M widened proximally and tapering in distal part; M slightly longer than S (Fig. 15 ). Hind coxa dorsally bare; hind tibia with one spur.

Metasoma on distinct petiole, longer than broad. Metasoma lanceolate, as long as combined length of mesosoma and head (Figs 13 , 14 ); Mt2 large with hind margin arched in middle. Cerci with setae subequal in length. Hypopygium situated at one-half length of metasoma. Ovipositor not much protruding.

Remarks.

The original description of the genus by Hedqvist (1973) indicated that the notauli were incomplete, but after studying the holotype and additional non-type material it was concluded that the notauli are complete.

Distribution.

Palaearctic.
