Atlanticus (Sinpacificus) fengyangensis Liu View in CoL sp. n.

( Fig. 3W View FIGURE 3 ; 4S View FIGURE 4 ; 5C View FIGURE 5 ; 6C View FIGURE 6 ; Table 2)

Holotype. Male, China: Zhejiang Prov., Longquan, Fengyangshan Mt. , 2009.VIII., Coll. Wu Chao, Ma Tingting.

Paratype. 1 male, 3 females, same data as in holotype .

Diagnosis. Medium-sized compared to the congeners. Pronotum narrowest in proximal one sixth part. Stridulatory file on underside of male left tegmen with 120 distinct teeth gradually becoming larger centrad ( Fig. 5C View FIGURE 5 ). Mirror on male right tegmen wider than long ( Fig. 6C View FIGURE 6 ). Male cercus robust and short, with stout, acute and abrupt incurved apical tooth, comparatively long, conical internal tooth positioned immediately below the apical one ( Fig. 4S View FIGURE 4 ).

Description. Holotype. Male. Disc of prozona and metazona typical. Pronotum narrowest in proximal one sixth, 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 the sixth abdominal tergum. Fore femora with 2 internal ventral spines. Middle femur without spines. Hind femur with 3-5 interior spines on ventral margin. 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 16 exterior and 26 interior spines on dorsal margins. Tenth abdominal tergum with a large central “trumpet”-shaped cleft ( Fig. 3W View FIGURE 3 ). Subgenital plate with a small “U”-shaped notch between styli, notch as half length of stylus.

Female. Tenth abdominal tergum with a central “U”-shaped notch. Cerci conical, with obtuse apex. Ovipositor long, apical half gradually recurved, with apex obliquely truncate. Subgenital plate distinctly transverse, emarginate in apical quarter, forming two obtuse lateral lobes.

Coloration. Generally reddish brown. Outer surface of two basal antennal joints, fastigium frontis, front and lateral surfaces of fastigium verticis, postocular fascia, lateral lobes of pronotum except a parallelogram-shaped area composed of ventral margin and ventral two thirds of posterior margin extending upwards to almost touch lateral carinae, and a central stripe separating upper and lower portion on hind femora shining blackish brown. Ventral spines of hind femora black.

Notes. The new species resembles A. (S.) palpalis in size, the length of male tegmen and of female ovipositor, but is most distinct in the shape of male cercus. It is similar to A. (S.) hoffmanni in the male cercus, but differs in body size, length and shape of pronotum, of male tegmina and of ovipositor.

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

Distribution. China (Zhejiang).
