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

( Fig. 1Q View FIGURE 1 ; 2R View FIGURE 2 ; 3R View FIGURE 3 ; 8C View FIGURE 8 ; 9R View FIGURE 9 ; 11S View FIGURE 11 ; Table 1)

Holotype. Male [IOZ(E)361987], China:, Gansu Prov.: Kangxian, Qinghe Forestry spot, 1400m, 1998.VII.1, Yang Xingke.

Diagnosis. Medium-sized compared to the congeners in Kangxiani Group ( Fig. 8C,G View FIGURE 8 ; 9R View FIGURE 9 ). Proximal one-third of stridulatory file on underside of male left tegmen with 28 distinct stridulatory teeth which gradually becoming larger centrad ( Fig. 1Q View FIGURE 1 ); central one third of stridulatory file with 26 indistinct teeth. Proximal portion of mirror of male right tegmen covered by pronotum ( Fig. 2R View FIGURE 2 ). Male tenth abdominal tergum with a trumpet-shaped central cleft in apical half. Male cerci short, robust, gradually acuminate to slightly incurved obtuse pointed apex, an internal uncinate tooth situated distad of centre ( Fig. 3R View FIGURE 3 ). Male subgenital plate with a very shallow “V”-shaped notch between styli, notch as one sixth of length of stylus ( Fig. 11S View FIGURE 11 ).

Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in basal third, and then gradually 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 at rest, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 8C View FIGURE 8 ; 9R View FIGURE 9 ). Fore femur with 4 interior spines on ventral margin. Middle femur with 2–3 external ventral spines in apical half. Hind femur with 3–7 exterior 5–7 interior 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 ventral spines on both margins, 2 exterior and 4 interior spines on dorsal margins. Hind tibia with 10 exterior and 11 interior spines on dorsal margins.

Coloration. Generally brown. The following parts shining black: the outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; two middle blocks on caudal margin of occiput; 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; wide fascia in three fourths of submarginal field of tegmen except basal marginal part. Stridulatory area and subapical portion of tegmen with dark brown veins. 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 species most resembles A. (A.) kangxiani sp. n. in the whole coloration, but distinctly differs by distinctly small size, and comparatively short male tegmen, male stridulatory apparatus and male cerci.

Etymology. The new species is named for its similarity with A. (A.) kangxiani sp. n..

Distribution. China (Gansu).
