Two new species of
Antenna usually yellow, with 1–3 anelli, 3 funicle segments, and 3-segmented clava. Mesosoma convex, pronotum very short, transverse; midlobe of mesoscutum about as long as broad, with a single row of adnotaular setae on each side; scutellum with two distinct longitudinal submedian lines and two setae behind the middle; propodeum with median carina, without plica. Tegula yellow. Fore wing with marginal and stigmal veins very thick; submarginal vein with only one dorsal seta; marginal vein very short, much shorter than costal cell; apical margin without setae. Metasomal terga with yellow areas or completely dark.
Palearctic region: China (Xinjiang), Kazakhstan, Russia, and Turkmenistan.
