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

( Fig. 1F View FIGURE 1 ; 2I View FIGURE 2 ; 3I View FIGURE 3 ; 4H View FIGURE 4 ; 7Q,R View FIGURE 7 ; 9I View FIGURE 9 ; 11H View FIGURE 11 ; Table 1)

Holotype. Male, China: Hebei Prov., Zhunhua, Eastern Tomb , collector unknown, 1930.VII.6-10.

Paratypes. Same data sa in holotype, 15 males, 9 females, 1930.VII.6 --10 (4 males, 2 females are nymphs); 2 males, 1 female, 1930.VII.11 --15; 1 male, 2 females, 1930.VII.16 --20.

Diagnosis. Small-sized compared to the congeners in Sinensis Group ( Fig. 7Q,R View FIGURE 7 ; 9I View FIGURE 9 ). Proximal half of stridulatory file on underside of male left tegmen with 35 distinct teeth which gradually becoming larger centrad ( Fig. 1F View FIGURE 1 ). Proximal part of mirror of male right tegmen covered by pronotum ( Fig. 2I View FIGURE 2 ). Male tenth abdominal tergum with a trumpet-shaped notch ( Fig. 4H View FIGURE 4 ). Male cercus most robust at base, equally narrowed to a slightly incurved obtuse pointed apex; an internal uncinate tooth situated distad of centre ( Fig. 3I View FIGURE 3 ). Apical margin of male subgenital plate with a deep “U”-shaped notch between moderately robust styli, notch slightly shorter than stylus ( Fig. 11H View FIGURE 11 ). Female ovipositor narrow (1.2 mm wide in middle), with apical two thirds moderately recurved (about 30 º angle) ( Fig. 7R View FIGURE 7 ).

Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in proximal one-third, and then abruptly 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 aslant caudad to posterior angle. Tegmen not extending beyond caudal margin of the second abdominal tergum when contracted, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 7Q View FIGURE 7 ; 9R View FIGURE 9 ). Fore femur with 1 interior ventral spine. Middle femur without spines. Hind femur with 3 ventral interior 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 10 exterior and 14 interior spines on dorsal margins.

Female. Size more robust than male. Tegmen not produced dorsally. Ovipositor twice the length of pronotum, with moderately recurved apical half (about 30º angle) ( Fig. 7R View FIGURE 7 ). Proximal one-third part of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncated at apex ( Fig. 7R View FIGURE 7 ). Subgenital plate distinctly transverse, apical margin emarginate in apical one-third and forming two obtuse triangular lobes.

Coloration. Generally 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 brown fascia along the lower margin extending a little above humeral notch; upper portion of pleurae; numerous spots on fore and middle legs; a robust line with indefinite striation separated the upper half from the lower half; wide fascia in one third portion of submarginal field of male tegmen. Blackish veins of stridulatory area on male left tegmen. Ventral spines of hind femur black.

Notes. This species and A. (A.) minor are smallest in the subgenus Atlanticus , but they differ from each other by structure of the male stridulatory apparatus and the female ovipositor. It resembles A. (A.) sinensis in coloration of blotches of the male tegmen, and the stripes of the male femur, but differs in its comparatively small size and the structure of the ovipositor.

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

Distribution. China (Hebei).
