(Figs 9 A–C, 10A–C) is distinguished from Woldstedtius patei (Dasch, 1964) (Fig. 11) by the orange legs, the less extensive pale colouration of the mesosoma and the less distinct carination of the propodeum (Fig. 10C). Woldstedtius patei , known from two specimens collected in the southern part of the Rocky Mountains in North America, has the fore and mid coxae orange, basally infuscate with the apices largely yellow (Fig. 11 A–C). The hind femur is orange with the inner side infuscate and the hind tibiae are whitish, apically infuscate and with a small subbasal black spot. Furthermore, the yellow shoulder mark, the yellow apices of the scutellum and postscutellum are more extensive in W. patei (Fig. 11 A–C) while the orange spot on the metapleuron is considerably smaller. Etymology The specific epithet aureotibialis (adjective) is derived from the colour of the hind tibia, aureo = golden. Description Fore wing length 3.1–4.2 mm. Body length 4.5–5.5 mm. Head in anterior view strongly transverse, central area strongly elevated. Inner orbits almost parallel (Figs 9B, 10B). Antennae with 22 flagellomeres. First flagellomere about 5 times as long as wide. Second flagellomere about 3.5–4 times as long as wide. Clypeus in basal third with a transverse ...
