Material examined. CHINA: Xinjiang: Tulufan (20–140 m), 24-VI-1958, leg Guang Wang (16) .

Redescription. Length 2.20–2.80 mm ( Fig. 73–76 View FIGURES 73–90 ). Vestiture on dorsum unicolorous, grayish to pale brown, or bicoloured, pale brown and reddish brown. Rostrum ( Fig. 195–198 View FIGURES 173–196 View FIGURES 197–220 ) in lateral view robust (Rl/Rw 5.00 in male, 5.57 in female; Rl/Pl 0.87–1.03 in male, 0.90–0.98 in female), feebly curved, slightly tapered in distal third, nearly of same shape in both sexes. Pronotum slightly wider than long (Pw/Pl 1.10–1.20), feebly curved at sides, distinctly narrower than elytra (Ew/Pw 1.30–1.45). Elytra suboval (El/Ew 1.40–1.55). Femora ( Fig. 283–284 View FIGURES 275–306 ) unarmed, tibiae ( Fig. 327 View FIGURES 307–339 ) without sexual characters. Third tarsomere distinctly wider than second tarsomere ( Fig. 340 View FIGURES 340–363 ). Claws ( Fig. 352 View FIGURES 340–363 ) with small medial teeth a little less long than half of claw, fastened to claw in basal half. Male genitalia: body of penis ( Fig. 383 View FIGURES 380–387 ) short, in dorsal view large, gradually distinctly narrowing from base to apex, with long thin blunted tip ( Fig. 418 View FIGURES 397–431 ), shorter than apodeme. Female genitalia: spermatheca see Caldara (1986); spiculum ventrale ( Fig. 474 View FIGURES 458–484 ) with arm joined in basal 1/3 then slightly spaced to apex.

Remarks and comparative notes. This species is distinguishable from the other species of the group known from China by a short rostrum which is poorly sexually dimorphic and the short, broad body of the penis.

Biology. This species lives on Alhagi , such as A. maurorum Medik. (= A. camelorum DC ) and A. pseudalhagi (M. Bieb.) Desv. ex B. Keller & Shap. in Central Asia ( Caldara, 1986; Karasjov, 1994).

Distribution. This species was previously known from European Russia and western to central Asia. New record from China (XIN).
