Black ( Fig. 1 ); two basal antennomere of antenna, mandible brownish yellow; palpi yellow; metasoma except first tergite dark brown; legs (except dark brown apical part of hind tibia and hind tarsus) yellowish brown; pterostigma and veins light brown; wing membrane hyaline. Variation. Antennal segments of ♀ 34(1) or 35 (1). Comparative diagnosis. This species is similar to A. incongrua Nees , but differs by having a wider face (twice wider than high versus 1.5–1.6 × in A. incongrua ); length of third antennal segment 4 × its width ( versus 5 times); vein m-cu of fore wing interstitial ( versus antefurcal); first tergite of metasoma 1.3 × as long as its apical width ( versus 1.5 times); distance between base of pterostigma and vein r 4.6 × longer than vein r ( versus 6.5 times). Etymology . Named “ hebeiensis ” because of the type locality of the holotype is situated in Hebei province .
