Ammophila chalybea KOHL 1906: 271 ,. Lectotype examined:, Russia: N. Mongolia: Ala-Shan (NHMW), present designation.

R e c o g n i t i o n Podalonia chalybea has a glabrous propodeal enclosure and the claws lack a small tooth near the base. In the female the prominent spine of the forecoxa varies in size: in most specimens it is a conical tooth, but in others it is spine-like. The mesopleuron is convex and distinctly striate. The color of the gaster is variable: most females have a black gaster with bluish reflections (417 specimens examined), some have a gaster that is partly reddish basally. The tibiae are partly pale (5 specimens). Some females have a black gaster without blue reflections. The female of P. chalybea is similar to P. atrocyanea but the flagellum is not as slender as in that species (fig. 14), (Flagellomere I: II = 1.6-1.8). The clypeus of P. chalybea is convex.

The male of Podalonia chalybea differs from the similar P. atrocyanea in having a peti- ole that is shorter than or equal to hindtarsomere I, and a more compact body and nearly always black legs. In addition, the mesopleuron on the posterior half and ventrally is irregularly transversely rugose, terga I-III (IV) are reddish-brown or with black spots on them, and in some male the gaster is all black. Penis valve: figs 27, 51, 76 and 110. Males from Mongolia cannot always be separated from P. atrocyanea .
