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 : 39-41

Atlanticus (Sinpacificus) huangfu Liu sp. n.

( Fig. 3 (Z2, Z3, Z4); 4Y, Z; 5H, I, J; 6H, I, J; 8S, U, V, W, X; 10G, H, I; 11Z; Table 2)

Holotype. Male [IOZ(E) 361528], China: Anhui Prov., Huangfushan Mt. , 1965.VI.13, collector unknown.

Paratype. Same data as in holotype, 1 male, 2 females, 1966.VIII.28; 2 males, 6 females, 1965.VI.7–VIII.2.

Diagnosis. Medium-sized compared to the congeners in the Pieli Group. Stridulatory file on underside of male left tegmen with 50 distinct teeth which gradually becoming larger centrad. Proximal half of mirror of male right tegmen concealed under pronotum. Female with ovipositor moderately robust (1.4 mm wide in middle), with apical half slightly recurved ( Fig. 8Q ).

Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in first transverse sulcus or at basal one fifth, and then gradually ampliate caudad. Lateral lobes of pronotum much longer than high; anterior margin very slightly concave, posterior margin oblique with a very indistinct central concavity, ventral margin aslant caudad to posterior angle. Tegmen expanded, extending to eighth abdominal tergum when constricted. Tegmen with clear longitudinal and cross veins; radial vein giving out one branch in apical one-fifth; flat dorsal and lateral planes at right angles to each other; MA+CuIP located in lateral plane; lateral plane deepest in apical third. Fore femur with 2-3 interior spines on ventral margin. Middle femur with 1 external ventral spine in apical half. Hind femur without ventral spines. Fore tibiae 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 22 exterior and 17 interior spines on dorsal margins.

Tenth abdominal tergum with a long and narrow central cleft from base. Cercus robust, short, of even width to small uncinate internal median tooth, apical half abruptly acuminate with a bluntly pointed tooth. Subgenital plate with a wide “V”-shaped notch between styli; notch one third of length of stylus ( Fig. 11Z ).

Female. Tenth abdominal tergum with a slight central “U”-shaped notch. Cercus conical, with obtuse apex. Ovipositor moderately straight, one and a half times the length of pronotum; apical half recurved with apex obliquely truncate. Apical margin of subgenital plate with a very obtusely angular tiny emargination.

Coloration. Generally dark reddish brown. The following parts shining black: the outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; lateral lobes of pronotum except a comparatively narrow fascia along the ventral margin; upper three quarters of posterior surface of fore femur, and posterior surface of fore tibia and fore tarsus; posterior surface of median legs and median tarsus; proximal upper margin of hind femora; a robust line with indefinite striation separated the upper half from the lower half in central one third part on anterior surface of hind femora; basal half radial areas between radial and subcostal veins of male tegmen. Ventral interior spines of hind femur black.

Variation. Two male paratypes possess much shorter wings than the holotype. However, all these specimens possess very similar male stridulatory apparatus. So we temporarily consider them as one species.

Notes. This new species differs from the congeners in Pieli Group by the mirror of male right tegmen and the shape of cleft of male tenth abdominal tergum.

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

Distribution. China (Anhui).
