Distribution.

Russia (Buryatia Rep.), *Kazakhstan, Tajikistan, Turkmenistan, Uzbekistan ( Popov 1935, 1949, 1967; current data).

Variability.

Labral tubercles in both sexes are positioned, typically, more or less close to the apical margin and rarely directly thereupon.

Females have well developed red body coloration. The labrum, clypeus, pronotal lobe, tegulae, mesepisternum, axillae, mesoscutellum, metanotum, legs, pygidial plate and sterna are always reddened. The antennae are mostly reddish, but with terminal flagellomeres usually brownish. The pronotum varies from reddish to partially black. The mesoscutum is mostly black, but red patterning sometimes also occurs laterally, or rarely it is almost entirely red-brownish. The propodeum varies from black to reddish. The metasomal terga vary from dark brown to red-brown with golden marginal zones; T5 is usually reddish.

Males are mostly black (excepting a red labrum, scape, pedicel, F1, pronotal lobe, tegulae, legs and pygidial plate). The clypeus is red (entirely or only in apical half). The mesepisternum, axillae and mesoscutellum are typically black, but sometimes can be partially or entirely red. The sterna vary from brownish to reddish. The pygidial plate apical margin is typically more or less bilobed, sometimes rather straight.
