Atlanticus (Atlanticus) jixiani Liu View in CoL sp. n.
( Fig. 1G View FIGURE 1 ; 2F View FIGURE 2 ; 3F View FIGURE 3 ; 4F View FIGURE 4 ; 7K View FIGURE 7 ; 9F View FIGURE 9 ; 11E View FIGURE 11 ; Table 1)
Holotype. Male [IOZ(E)1340331], Shanxi Prov., Jixian County, Daokou , 1991.IX.15, Coll. Liu Jupeng.
Diagnosis. Small-sized compared to the congeners in Sinensis Group ( Fig. 7K View FIGURE 7 ; 9F View FIGURE 9 ). Proximal two thirds of stridulatory file on underside of male left tegmen with 50 distinct teeth which gradually becoming larger centrad ( Fig. 1G View FIGURE 1 ). Mirror of male right tegmen possessing a sclerotized transverse vein in proximal one-tenth portion, which is concealed beneath pronotum ( Fig. 2F View FIGURE 2 ). Male tenth abdominal tergum with a central “heart”-shaped notch at apex ( Fig. 4F View FIGURE 4 ). Male cercus mostly robust at base, equally narrowed to a slightly incurved obtuse pointed apex; an internal uncinate tooth situated distad of centre ( Fig. 3F View FIGURE 3 ). Apical margin of male subgenital plate with a wide shallow “U”-shaped notch between styli, notch as half length of stylus ( Fig. 11E View FIGURE 11 ).
Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in proximal quarter, and then abruptly ampliate caudad. 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 not extending beyond middle of the third abdominal tergum at rest, with a reticulation of poorly defined veins; posterior portion convex ( Fig. 7K View FIGURE 7 ; 9F View FIGURE 9 ).
Leg spination. Fore femur with 1 interior dorsal spine. Middle femur without ventral spines. Hind femur with 1-2 exterior ventral spines. Fore tibia with 3 exterior spines on dorsal 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 18 exterior and 17 interior spines on dorsal margins.
Coloration. Generally 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 brown fascia along the lower margin extending a little above humeral notch. The following parts shining blackish brown: upper portion of pleurae; proximal part, upper central part, and apical part of fore femora; proximal half of fore tibiae; a line on lower half of middle femora; a robust line with indefinite striation separated the upper half from the lower half; proximal upper portion of hind femora. Disc of pronotum dark brown. Abdominal tergites testaceous with indefinite yellowish brown striations. Male tegmen reddish brown with blackish subcostal and radial veins, stridulatory area on male left tegmen dark with blackish veins. Ventral spines of median femur blackish.
Female unknown.
Notes. This species most resembles A. (A.) sinensis in size, but differs in the coloration (especially of male tegmen), the width of male tegmen, male stridulatory apparatus and male abdominal apex.
Etymology. The new species is named for its type locality.
Distribution. China (Shanxi).
