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

( Fig. 2Q View FIGURE 2 ; 3Q View FIGURE 3 ; 4P View FIGURE 4 ; 8B View FIGURE 8 ; 9Q View FIGURE 9 ; 11R View FIGURE 11 ; Table 1)

Holotype. Male [IOZ(E)361925], China: Gansu Prov.: Wenxian, Fanba , 800m, 1998.VI.26, Coll. Yao Jian.

Diagnosis. Large-sized compared to the congeners in Kangxiani Group ( Fig. 8B View FIGURE 8 ; 9Q View FIGURE 9 ). A few proximal part of mirror of male right tegmen covered by pronotum; proximal part of mirror possessing an indistinct sclerotized transverse vein ( Fig. 2Q View FIGURE 2 ). Male tenth abdominal tergum with a conversely triangular central cleft from basal quarter ( Fig. 4P View FIGURE 4 ). Male cercus moderately long, heavy, equally acuminate to apex, an internal uncinate tooth situated distad of centre; apical half gently incurved with an obtusely pointed apex ( Fig. 3Q View FIGURE 3 ). Apical margin of male subgenital plate with a shallow “V”-shaped notch between styli, notch as one-quarter of length of stylus ( Fig. 11R 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 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 caudal margin of the fourth abdominal tergum at rest, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 8B View FIGURE 8 ; 9Q View FIGURE 9 ). Apical quarter of fore femur with 2 interior spines on ventral margin. Apical quarter of middle femur with 0–2 external ventral spines in apical half. Hind femur with 3–5 exterior and 4–7 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, 2–3 exterior and 4 interior spines on dorsal margins. Hind tibia with 18 exterior and 17 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; indefinite lines and striation in disc of pronotum; lateral lobes of pronotum except a comparatively wide brown fascia along the lower margin extending a little above humeral notch; upper portion of pleurae; numerous spots on fore and middle legs; a fascia and two basal large blocks in upper quarter of fore and mid femora; a robust line with indefinite striation in lower third part of hind femur; wide fascia in four fifths of submarginal field of male tegmen; a few spots in subapical portion of tegmen. Veins of stridulatory area on male left tegmen dark brown. Ventral spines of hind femur black.

Female unknown.

Notes. This species most closely resembles A. (A.) kangxiani sp. n. in its coloration, but differs by the length of male tegmen, male stridulatory apparatus and structure of male genitalia.

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

Distribution. China (Gansu).
