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

( Fig. 1M View FIGURE 1 ; 2N View FIGURE 2 ; 3N View FIGURE 3 ; 4N View FIGURE 4 ; 7Y,Z View FIGURE 7 ; 9O View FIGURE 9 ; 11M View FIGURE 11 ; Table 1)

Holotype. Male, Hebei Prov.: Xiaowutai, Beitai , 1800-2400m, 1964.VIII.14, Coll. Li Beiqian [IOZ(E)1340982].

Paratype. 2 males [IOZ(E) 361969, 361970], 1 female [IOZ(E)1340998], same data as in holotype ; 1 male [IOZ(E)361912], same data as in holotype, 1400-2700m, 1964.VIII.12.

Diagnosis. Large-sized compared to others in the Sinensis Group ( Fig. 7Y,Z View FIGURE 7 ; 9O View FIGURE 9 ). Proximal two thirds of stridulatory file on underside of male left tegmen with 45 distinct teeth which gradually becoming larger centrad ( Fig. 1M View FIGURE 1 ). Proximal part of mirror of male right tegmen covered by pronotum ( Fig. 2N View FIGURE 2 ). Apical margin of male tenth abdominal tergum with a very conversely triangular notch from basal quarter ( Fig. 4N View FIGURE 4 ). Male cercus most robust at base, equally narrowed to internal uncinate tooth in distal portion of basal half, and then gently incurved in apical quarter with an obtuse pointed apex ( Fig. 3N View FIGURE 3 ). Apical margin of male subgenital plate with a broad “U”- shaped notch between robust styli, notch as long as stylus. Female ovipositor narrow (1.3mm wide in middle) and long, with apical half moderately recurved (about 15º angle).

Description. Holotype. Male. Disc of prozona slightly convex, metazona approximately flat. Pronotum narrowest in proximal one-third, and then gradually ampliate caudad. Posterior margin of disc of pronotum with distinct central emargination; lateral lobes of pronotum slightly 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 caudal margin of the third abdominal tergum, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 7Y View FIGURE 7 ; 9O View FIGURE 9 ). Fore femur with 1 interior ventral spine. Middle femur with 0–2 external ventral spines. Apical half of hind femur with 1 exterior ventral spine. 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 12 exterior and 9 interior spines on ventral margins.

Female ( Fig. 7Z View FIGURE 7 ). Ovipositor twice longer than pronotum, with moderately recurved apical half. Proximal quarter of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncated in apex. Subgenital plate distinctly transverse, emarginated in apical one third, forming two obtuse triangular lobes.

Coloration. Generally brownish pale. The following parts shining black: outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; upper portion of pleurae. Lateral lobes of pronotum blackish brown except a comparatively narrow brown fascia along the lower margin extending a little above humeral notch. Fore and median legs and hind tarsus dark brown. Disc of pronotum generally reddish brown; proximal part before first transverse sulcus and metazona with numerous indefinite dark striation, and remainder with a few scattered dark dots. Male tegmen pale yellowish, stridulatory area brown; a wide fascia in two thirds of basal field between MA+CuIA and costal margin of tegmen brown, radial and MA+CuIA veins and veins in stridulatory area on left tegmen reddish brown. Base of each femur, tibia and ventral surface of each tarsus blackish; numerous brown spots on fore and middle legs; a robust brown line with indefinite striation separated upper half from the lower half of hind femur. Abdominal tergite brown, with reddish brown posterior margins and numerous indefinite dark brown dots. Abdominal sternites yellow.

Notes. Male of this species is smallest among those distributed in Xiaowutai Mountain, Hebei Province. It differs from A. (A.) parabeitai sp. n. in the body size, length and shape of pronotum, length of male tegmen, comparatively long styli of the male subgenital plate.

Etymology. The new species is named for its similarity with A. (A.) beitaii sp. n..

Distribution. China (Hebei).
