Material.

Holotype female (LUZM), glued to a point, labelled "DENMARK: Glatved, 12km S Grenaa, 56°18'N, 10°51'E, 8.vii.1998, R. Danielsson". Paratypes. 39♀ 1♂: DENMARK: 26♀ with same label data as holotype (BMNH, LUZM, ZMUC); 1♀ from same locality as holotype but collected 4.vii.2001 (ZMUC). FRANCE: 1♀ "Montpellier le Vieux, 10.vii.1977, M.J. Gijswijt" (RMNH). GREECE: 4♀ "Loanina, Ipiros, Metsovo, Katara, 1600m, 24.vi.1989, M.J. Gijswijt" (RMNH). HUNGARY: 1♀ 1♂ " Veszprém Co., Nyirád, 47°00'N, 17°27'E, 213m, 27.vi.2010, C. Hansson" (BMNH). SWEDEN: 6♀ “Bohuslän, Sydkoster, Kilesand, 6.vii.1956, E. Kjellander" (NHRS).

Diagnosis.

Clypeus usually pale brown with weak to strong metallic tinges (Figs 339, 340), i.e. paler than face and frons (a few female specimens with clypeus completely metallic); female antennal clava 3-segmented (Fig. 344); male antenna with verticillate setae on flagellomeres 1-4 (Fig. 348); forewing speculum open below (Fig. 341), admarginal setae 6-10 arising mainly from membrane, radial cell bare; femora metallic, tibiae and tarsi dark brown (Fig. 336); petiolar foramen large and median propodeum hence very short (Fig. 343). Similar to Omphale clypealis but with clypeus darker, shape of stigmal vein different with base very narrow and rapidly expanding towards apex (Fig. 341), admarginal setae in forewing on average fewer, female gaster longer.

Description.

Face bluish green metallic to golden green (Fig. 339), with weak reticulation (Fig. 345); clypeus pale brown with weak to strong metallic tinges, in some specimens (from Greece and Hungary) golden green to bluish green metallic, smooth, trapezoid to semicircular with ventral margin straight, 1.5 × as wide as high; gena golden green; lower frons bluish green metallic, with raised and strong reticulation; interscrobal area reticulate; antennal scrobes join frontal suture separately, or join on frontal suture; frontal suture V-shaped; upper frons golden green, with raised and weak reticulation; vertex golden green, inside ocellar triangle with engraved and weak reticulation, outside with raised and weak reticulation and partly smooth (Fig. 346).

Entire lateral mesosoma bluish green metallic to golden green (Fig. 336); transepimeral sulcus curved forwards. Propodeum golden green (Fig. 337), smooth (Fig. 343); propodeal callus with two setae. Coxae and femora bluish green metallic (Fig. 336); tibiae and tarsi dark brown; midleg with first tarsomere 0.3 × as long as length of tarsus. Forewing transparent, veins pale brown, setae dark brown (Fig. 341); speculum open; admarginal setae 6-10, arising mainly from wing membrane; radial cell bare; postmarginal vein 0.8 × as long as stigmal vein; stigmal vein narrow at base and rapidly expanding towards apex. Hind wing transparent, apex pointed (Fig. 341). Forewing WIP (Fig. 342) with apical ½ magenta with blue margin, basal ½ yellow with narrow bands in magenta and blue towards base.

Antenna with pedicel + flagellum 2.8 × as long as distance between eyes; flagellomeres with verticillate setae (Fig. 348); clava 1-segmented. Face bluish green metallic (Fig. 340), strigose-reticulate (Fig. 349); clypeus brown with metallic tinges, with weak sculpture, rectangular, 1.6 × as wide as high.

Etymology.

From the Latin parma = small shield, referring to the palish clypeus (clypeus = shield).
