description: Atlanticus (Atlanticus) zhouzhii Liu sp. n.   
(Fig. 1R; 2S; 3S; 4R; 8F; 9S; 11O; Table 1)  
Holotype. Male, China: Shaanxi Prov.: Zhouzhi, Houzhenzi, 1350m, 1999.VI.25, Liu Chanmin [IOZ(E)360495].  
Diagnosis. Large-sized compared to others in the Sinensis Group (Fig. 8F; 9S). Stridulatory file on underside of male left tegmen with 91 distinct teeth which gradually becoming larger centrad (Fig. 1R). Proximal portion of mirror of male right tegmen covered by pronotum (Fig. 2S). Male tenth abdominal tergum with a wide converse, trumpet-shaped central cleft from basal quarter (Fig. 4R). Male cercus moderately long, heavy, acuminated to an internal uncinate tooth in basad of centre, then abruptly narrowed, and slightly incurved in apical one-third portion with an obtuse pointed apex (Fig. 3S). Apical margin of male subgenital plate with a deep “V” -shaped notch between robust styli, notch half length of stylus (Fig. 11O).  
Description. Holotype. Male. Disc of prozona slightly convex, metazona approximately flat. Pronotum narrowest in basal 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 aslant caudad to posterior angle. Tegmen extending to caudal margin of the fifth abdominal tergum when contracted, with a reticulation of poorly defined veins; posterior portion convex (Fig. 8F; 9S).  
Leg spination. Middle femur with 2 external ventral spines in apical half. Hind femur with 5 ventral spines on both margins. Fore tibia with 3 dorsal spines on exterior margin and 6 ventral spines on both margins. Middle tibia with 6 interior spines on both margins, 2 exterior and 4 interior spines on dorsal margins. Hind tibia with 20 exterior and 16 interior spines on dorsal margins.  
Coloration. Generally reddish brown. The following parts shining black: the inner surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; indefinite lines and spots in disc of pronotum; lateral lobes of pronotum except a comparatively narrow brown fascia along the lower margin extending a little above humeral notch; upper portion of pleurae; numerous spots on fore and middle legs; a wide fascia in three fourths of submarginal field of tegmen. Several dots in areas between medial and radial veins. Dark brown veins in stridulatory area on left tegmen. Ventral spines of hind femur black. Lower portion of hind femur dark brown. Numerous brown dots in upper portion of hind femur.  
Female unknown.  
 Notes. This new species most closely resembles A. (A.) macropterus sp. n. in the body size and comparison between male tegmen and pronotum, but differs in male stridulatory apparatus, structure of the male tenth abdominal tergum and the male subgenital plate.   
Etymology. The new species is named for its type locality.  
Distribution. China (Shaanxi).
