( Fig. 1J ; 2J ; 3L ; 4I ; 7U ; 9L ; 11I ; Table 1) Holotype . Male [IOZ(E)361974], China : Hebei Prov. , Zhengding (Original label: Chahar, Yangjiaping), 1931.VII.3 , Coll. O. Peil. Diagnosis. Large-sized compared to the congeners in Sinensis Group. Proximal five-sixths of stridulatory file on underside of male left tegmen with 55 distinct teeth gradually becoming larger centrad. Proximal portion of mirror of male right tegmen covered by pronotum. Apical margin of male tenth abdominal tergum with a wide “U”-shaped cleft in apical one third. Male cercus narrow, long, heavy of equal width to an internal uncinate tooth in central one-third, then abruptly narrowed, with obtuse pointed apex slightly incurved. Apical margin of male subgenital plate with a shallow broad “U”-shaped notch between moderately robust styli, notch one-quarter of length of stylus ( Fig. 11I ). Description. Holotype . Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in proximal one third, and then gradually ampliate caudad. Lateral lobes of pronotum slightly longer than high, deepest at middle; anterior margin very slightly concave, posterior margin oblique with a very indistinct central concavity, ventral margin slanting caudad to posterior angle. Tegmen extending to the third tergum at rest. Tegmen with a reticulation of poorly defined veins; posterior portion convex. Fore femur without ventral spines. Apical half of hind femur with 3 exterior and 4 interior spines on ventral margins. Fore tibia with 3 dorsal spines on exterior margin and 6 ventral spines on both margins. Middle tibia with 6 ventral spines on both margins, 2 exterior and 4 interior spines on dorsal margins. Hind tibia with 17 exterior and 16 interior spines on dorsal margins. Coloration. Generally brown. The following parts shining black: outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; upper portion of pleurae. Occiput brown. Disc of pronotum testaceous with a brown stripe before first transverse sulcus; lateral lobes brown, with half of upper quarter below lateral carinae testaceous. Tegmen reddish brown; subcostal margin dark testaceous. Fore and median legs, apical one-third part and a broad stripe separating the upper half from the lower half of hind femora, hind tibiae, hind tarsi dark brown. Ventral spines of hind femur dark brown. Abdominal tergite testaceous, with blackish caudal margin. Female unknown. Notes. The new species resembles A. (A.) robustus in the body shape, but distinctly differs in the structure of the male cerci. Etymology. The new species is named for its comparatively long tegmen when comparing with other sympatric species in the subgenus. Distribution. China ( Hebei ).
