description: Atlanticus (Atlanticus) minimus Liu sp. n.   
(Fig. 1L; 2L; 3K; 4K; 7W; 9K; 11K; Table 1)  
Holotype. Male [IOZ(E)361999], China: Hebei Prov., Zhengding (Original label: Chahar, Yangjiaping), 1931.VII.3, Coll. O. Peil.  
Diagnosis. Medium-sized compared to the congeners in Sinensis Group. Central half of stridulatory file on underside of male left tegmen with 41 distinct teeth gradually becoming larger centrad (Fig. 1L). Apex of mirror of male right tegmen with the only portion not covered by pronotum (Fig. 2L). Apical margin of male tenth abdominal tergum with a conversely heart-shaped central cleft from basal one-sixth part (Fig. 4K). Male cercus short, slightly acuminated to an internal uncinate tooth in basad of centre, then abruptly narrowed, and slightly incurved in apical half with an obtuse pointed apex (Fig. 3K). Apical margin of male subgenital plate with a wide “U”-shaped notch between slender styli, notch one-third of length of stylus (Fig. 11K).  
Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in proximal quarter, and then gradually 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 slanting caudad to posterior angle. Tegmen extending to the second abdominal tergum at rest, with a reticulation of poorly defined veins; posterior portion convex. Fore femur with 2 interior ventral spines. Middle femur with 1 external ventral spine in apical quarter. Hind femur with 1 ventral spine on both margins. 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 18 exterior and 21 interior spines on dorsal margins.  
Coloration. Generally brown. The following parts shining black: the outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; upper portion of pleurae. Disc of pronotum rust-like with a few ill-defined yellow striations and spots; triangular area comprising half of anterior margin and proximal quarter of lateral carinae reddish brown, upper one-third of caudal half of lateral lobe blackish brown, remainder brown. Tegmen pale yellowish, stridulatory area brown with dark veins; a wide fascia between radial vein and costal margin reddish brown. Central three -fifths of a robust line separating the upper half from the lower half of hind femur brown. Ventral spines of hind femur dark brown.  
Female unknown.  
 Notes. This new species resembles A. (A.) macropterus sp. n. and A. (A.) medius sp. n. in the shape of body and pronotum, but differs by the length of male tegmen, the male stridulatory apparatus and the apex of the male abdomen.   
Etymology. The new species is named for its comparatively short tegmen when comparing with the codistributor.  
Distribution. China (Hebei).
