Liu, Chun-Xiang, 2013, Review of Atlanticus Scudder, 1894 (Orthoptera: Tettigoniidae: Tettigoniinae) from China, with description of 27 new species, Zootaxa 3647 (1), pp. 1-42 : 13

Atlanticus (Atlanticus) jiuchongensis Liu sp. n.

( Fig. 7I ; Table 1)

Holotype. Female [IOZ(E)361824], China: Hubei Prov., Shennongjia, Jiuchong , 700m, 1998.VII.20, Coll. Zhou Hongzhang.

Diagnosis. Female ovipositor robust (1.6mm wide in middle) compared with other species in the subgenus, with apical half slightly recurved. Hind femur three times longer than pronotum.

Description. Holotype. Female. Large-sized compared to the congeners in the subgenus Atlanticus . Disc of prozona slightly convex, and metazona slightly slanting from middle line to lateral carinae. Pronotum narrowest in proximal one third, and then gradually ampliate caudad. Lateral lobes of pronotum much longer than high, deepest before middle; anterior margin very slightly concave, posterior margin oblique with a distinct central concavity; ventral margin slanting caudad. Tegmen not produced dorsally. Apical half of hind femur with 5 exterior and 5-6 interior spines on ventral margins. Fore tibia with 1 dorsal exterior spine and 6 ventral spines on both margins. Middle tibia with 1 dorsal interior spine and 6 ventral spines on both margins. Hind tibia with 24 exterior and 19 interior spines on dorsal margins.

Ovipositor twice the length of the pronotum, with slightly recurved apical one-third part (about 10º angle). Proximal quarter of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncate in apex. Subgenital plate distinctly transverse, apical margin emarginate in apical one sixth, forming two obtuse triangular lobes.

Coloration. Generally dark brown. The following parts are shining black: outer surface of two basal antennal joints; fastigium frontis; lateral surfaces of fastigium verticis; postocular fascia; upper portion of pleurae. The following parts are shining blackish brown: central one third part separating upper portion from lower portion in proximal half of hind femora; lateral lobes of pronotum except a comparatively narrow yellowish brown fascia along the lower margin extending a little above humeral notch; a little proximal portion of anterior surface of hind femora. Numerous spots on fore and middle legs dark brown. Ventral spines of hind femur black. Abdominal tergite dark brown.

Male unknown.

Notes. This new species differs from other Chinese congeners in the subgenus Atlanticus by the shape of body, length and shape of ovipositor. It mostly resembles A. (A.) kulingensis in the shape of the ovipositor, but differs in details of the ovipositor. Consequently I temporarily put into the Kulingensis Group, but its true placement can not be determined until its male has been discovered.

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

Distribution. China (Hubei).
