Atlanticus (Atlanticus) zhongyangi Liu View in CoL sp. n.

( Fig. 1I View FIGURE 1 ; 2H View FIGURE 2 ; 3H View FIGURE 3 ; 4G View FIGURE 4 ; 7L View FIGURE 7 ; 9H View FIGURE 9 ; 11G View FIGURE 11 ; Table 1)

Holotype. Male [IOZ(E)1343235], China: Shanxi Prov., Zhongyang , 1998.VIII.1, Coll. Wang Shufang.

Diagnosis. Small-sized compared to the congeners in Sinensis Group ( Fig. 7L View FIGURE 7 ; 9H View FIGURE 9 ). Proximal two thirds of stridulatory file on underside of male left tegmen with 41 distinct teeth which gradually becoming larger centrad ( Fig. 1I View FIGURE 1 ). Mirror of male right tegmen not concealed beneath pronotum, with a sclerotized transverse vein in proximal one-ninth ( Fig. 2H View FIGURE 2 ). Male tenth abdominal tergum with a comparatively wide “trumpet”-shaped notch ( Fig. 4G View FIGURE 4 ). Male cercus robust at base, equally narrowed to a slightly incurved obtuse pointed apex; internal uncinate tooth situated basad of centre ( Fig. 3H View FIGURE 3 ). Apical margin of male subgenital plate with a wide, shallow “V”- shaped notch between styli, notch one-third of length of stylus ( Fig. 11G View FIGURE 11 ).

Description. Holotype. Male. Disc of prozona slightly convex, metazona approximately flat. Pronotum narrowest in proximal one-third, and then abruptly ampliate caudad. Lateral lobes of pronotum 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 caudal margin of the second abdominal tergum when at rest, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 7L View FIGURE 7 ; 9H View FIGURE 9 ). Middle femur with 1 external ventral spine in apical one-third. Hind femur with 2 exterior and 7 interior ventral spines. 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 9 exterior and 8 interior spines on dorsal margins.

Coloration. Similar to A. (A.) jixiani sp. n., except testaceous disc of pronotum and grayish brown abdominal tergite.

Female unknown.

Notes. The new species resembles A. jixiani sp. n. and A. minor sp. n. in the coloration and body size, but distinctly differs by the male stridulatory apparatus and male abdominal apex.

Etymology. The new species is named for its type locality.

Distribution. China (Shanxi).
