Atlanticus (Atlanticus) hefengensis Liu, 2013

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 : 13-14

Atlanticus (Atlanticus) hefengensis Liu sp. n.

( Fig. 7J ; Table 1)

Holotype. Female [IOZ(E)1340051], China: Hubei Prov., Shennongjia, Hefeng , Fenshuiling , 1400m, 1989.VIII.1, Coll. Yang Longlong.

Diagnosis. Ovipositor moderately robust (1.2mm wide in middle) compared with other species in the subgenus, with apical one-third slightly recurved. Hind femur twice the length of the pronotum.

Description. Holotype. Female. Medium-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 quarter, and then gradually ampliate caudad. Lateral lobes of pronotum slightly longer than deep, deepest before middle; anterior margin very slightly concave, posterior margin oblique with a distinct central concavity, ventral margin slanting caudad to posterior angle. Tegmen not produced dorsally. Fore femur with 3 ventral interior spines. Middle femur with 2 ventral exterior spines. Apical half of hind femur with 2–4 exterior and 2 interior spines on ventral margins. Fore tibia with 0–1 dorsal exterior spine and 6 ventral spines on both margins. Middle tibia with 3 dorsal interior spines and 6 ventral spines on both margins. Hind tibia with 18 dorsal spines on both margins. Ovipositor twice the length of pronotum, with slightly recurved apical one-third (about 10º angle). Proximal one-third of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncate at apex. Subgenital plate distinctly transverse, distal margin emarginate in one-third, forming two obtuse triangular lobes.

Coloration. Generally brown. The following parts are shining blackish brown: outer surface of two basal antennal joints; fastigium frontis; lateral surfaces of fastigium verticis; postocular fascia. The following parts are shining dark brown: upper portion of pleurae, small region above humeral notch of lateral lobes of pronotum; a middle line separating upper portion from lower portion of hind femora; dorsal surface of hind femur. 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 length of hind femur, length and shape of female ovipositor. 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).
