( Fig. 7S ; Table 1) Holotype . Female [IOZ(E)361479], China : Hebei Prov. , Weichang , Bashang , Huamugou , 1626m , N42°36.625´ , E117°21.622´ , 2003.IX.21 , Coll. Liu Chunxiang. Diagnosis. Female ovipositor narrow ( 1.1mm wide in middle) and long, with apical half moderately recurved (about 30º angle). Hind femur twice the length of the pronotum. Description. Holotype . Female. Small-size compared to the congeners in the subgenus Atlanticus . Disc of prozona slightly convex, and metazona slightly slanting from middle line to lateral carinae. Pronotum narrowest in proximal one third, and then gradually ampliate caudad. Lateral lobes of pronotum slightly longer than deep, deepest before middle; anterior margin very slightly concave, posterior margin oblique with a distinct central concavity, ventral margin slanting caudad to posterior angle. Tegmen not produced dorsally. Fore femur with 0-1 interior ventral spine. Apical half of hind femur with 2-4 exterior and 3–5 interior spines on ventral margins. Fore tibia with 2 dorsal spines on exterior margin and 6 ventral spines on both margins. Middle tibia with 2 exterior spines and 3 interior spines on dorsal margins, 6 ventral spines on both margins. Hind tibia with 15 exterior and 13 interior spines on dorsal margins. Ovipositor twice half longer than pronotum, with moderately recurved apical half. Proximal quarter of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncated in apex. Subgenital plate distinctly transverse, emarginate in apical half, forming two obtuse triangular lobes. Coloration. Generally brown. The following parts are shining blackish brown: outer surface of two basal antennal joints; fastigium frontis; lateral surfaces of fastigium verticis; a little proximal portion of anterior surface of hind femora. The following parts are shining dark brown: postocular fascia; upper portion of pleurae; a central line separating upper from lower parts of hind femora; lateral lobes of pronotum except a comparatively wide brown fascia in lower half extending a little upwards in middle and above humeral notch. Numerous spots and indefinite striation on legs dark brown. Ventral spines of hind femur black. Posterior portion of each abdominal tergum reddish brown. Male unknown. Notes. This new species is related to A. wudangensis Liu sp. n. as indicated by size and coloration, but differs in the shape, length and width of the ovipositor. Etymology. The new species is named for the habitat. The type locality “Weichang, Bashang” lies in the southern edge of Inner Mongolia Plateau. Distribution. China ( Hebei ).
