Material.

Holotype female (BMNH), glued to a card, labelled: "SWEDEN: Skåne, Häckeberga swamp, 55°34'N, 13°25'E, 25.vii.2006, C. Hansson & E. Shevtsova". Paratype. 1♀ "SWEDEN: Skåne, Lake Kranke, Lottagården, 55°42'N, 13°29'E, 6.vi.2006, C. Hansson & E. Shevtsova" (BMNH).

Diagnosis.

Several body parts pale non metallic: frons with interscrobal area and parts below level of toruli yellowish brown and smooth (Fig. 199); scutellum with three wide longitudinal stripes (Fig. 200), lateral ⅓ yellowish brown and median ⅓ golden; pronotum, propleuron, prepectus and mesepisternum yellowish brown (Fig. 198); legs yellowish brown with dark brown tarsi (Fig. 198); female gaster short, 1.3 × as long as mesosoma (Fig. 198). Similar to Omphale tenuicornis but female flagellum much shorter, frons reticulate, with fewer admarginal setae (4), shorter postmarginal vein (1.0 × as long as stigmal vein), and stigmal vein enlarged.
