( Fig. 1B ; 2B ; 3B ; 4B ; 7B,F ; 9B ; 11B ; Table 1) Holotype . Male [IOZ(E)1340111], China : Kiangsu Prov. : Haichow, 1926.VII, Coll. O. Piel. Paratype . 1 female [IOZ(E) 1340110], same data as in holotype . Diagnosis. Large-size compared to the congeners in Kulingensis Group ( Fig. 7B,F ). Proximal three quarters of stridulatory file on underside of male left tegmen with 58 distinct teeth gradually becoming larger centrad ( Fig. 1B ). Proximal one-third of mirror of male right tegmen concealed by pronotum ( Fig. 2B ). Male tenth abdominal tergum with a wide “U”-shaped cleft in apical half ( Fig. 4B ). Male cercus forcipate, moderately long, heavy of equal width to an internal uncinate tooth in basal one third part, then abruptly narrowed, and gently incurved in apical one third portion with an obtuse pointed apex ( Fig. 3B ). Apical margin of male subgenital plate nearly flat, with a very shallow wide “U”-shaped emargination between styli ( Fig. 11B ). Female ovipositor robust ( 1.5mm wide in middle) with moderately recurved apical half (about 30º angle). Proximal one-third of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncated. FIGURE 5. Stridulatory file on underside of male left tegmen. (A) A.

(Photo by Mr. Mai) Description. Holotype . Male. Disc of prozona distinctly convex, and metazona approximately flat. Pronotum narrowest in proximal one-third, and then gradually ampliate caudad. Lateral lobes of pronotum slightly higher than long, 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 not extending beyond middle of the second abdominal tergum with a reticulation of poorly defined veins; posterior portion convex ( Fig. 7B ; 9B ). Fore and middle legs lost. Hind femur with 0-4 ventral interior spines. Hind tibiae with 22 exterior and 20 interior spines on dorsal margins. Female ( Fig. 7F ). Form more robust than male. Ovipositor less than twice length of pronotum. Apical margin of tenth abdominal tergum and subgenital plate slightly emarginate. Coloration. Generally pale yellow. The following portions shining black: the inner surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia. The following parts dark brown: upper portion of pleurae; wide fascia in three quarters of basal field between radial vein and costal margin of male tegmen and veins in stridulatory area on male left tegmen; upper surface in proximal one eighth part of hind femora. Notes. This new species most closely resembles A. kulingensis based on the shape of male cercus, but distinctly differs in the shape of pronotum, the comparatively small mirror of male right tegmen, and the shape of the ovipositor. Etymology. The new species names for its similarity to A. kulingensis . Distribution. China ( Jiangsu ).
