Figs. 3, 4 View FIGURES 1 – 12 , 58 View FIGURES 57 – 70 , 72 View FIGURES 71 – 84 , 86 View FIGURES 85 – 98 .
The smallest of the Asian species of Leiopus ( Figs 3–4 View FIGURES 1 – 12 ). Body length similar to the smallest European species L. femoratus Fairmaire, 1859 . Integument of entire body black. Colour pattern on pronotum and elytra resemble small specimens of the European species L. punctulatus Paykull, 1800 . Elytra with short black pubescence interrupted by a grey, horizontally placed V-shaped marking medially and a narrow greyish band near apex (but not reaching apex as in L. punctulatus ). Elytra smooth and not costate, with a complete lack of tufted tubercles. Anterior part of each elytron between scutellum and humeri with a small raised area or rounded crest with coarser punctures (remaining punctures on elytra fine and sparse). Pronotum only slightly wider than long, without anterior tubercles (pronotum in L. punctulatus has distinct tubercles), with weak, whitish or grey pubescence at the base of the very small lateral spines. Last abdominal segment in male rounded or slightly convex. Ovipositor not elongated and with a rounded apex. The small size, black integument, colour patterns on elytra, lack of costae and tufted tubercles on elytra easily separating this species from all other species of Leiopus from China. The male genitalia characters similar to the European species L. punctulatus (cf. Sama, 1985). Examined male: length 6.0 mm, width 2.0 mm; female: length 6.8 mm, width 2.3 mm. Aedeagus: Approx. 1.0 mm long, relatively slender, narrowed and strongly curved towards apex, dorsal ridge as wide as ventral ridge ( Fig. 58 View FIGURES 57 – 70 ). The U-shaped sclerites at proximal end of basal segment fine, and the median sclerite inside the internal sac forming a short straight shaft (approx. 0.1 mm long) narrowing at either end; surrounding intersegmental membrane with very fine, rounded micro-reticulation. The median sclerite inside the internal sac shorter and the intersegmental membrane with a much finer micro-reticulation than in the closely related European species L. punctulatus . Tegmen: Approx. 1.1 mm long, parameres slender and slightly flattened dorso-ventrally at apex, well separated medially along inner margin but curved inwards at apex ( Fig. 72 View FIGURES 71 – 84 ). Parameres with a dorsally longitudinal ridge. Apex evenly rounded along entire posterior margin, with fringes of short, yellowish hairs well concentrated at edge of apex. No micro-reticulation on parameres. Base of tegmen extended and strongly curved dorso-ventrally towards the middle. Tergite VIII: Approx. 0.5 mm long, dark brown with posterior margin forming a straight line ( Fig. 86 View FIGURES 85 – 98 ), covered with short, very fine brownish hairs distally towards the posterior margin. Surface with no micro-reticulation. Spermatheca: Brownish, relatively short, widened at base, and acutely curved (folded 90°) towards apex. Apex with an elongated head. Similar in shape to L. syriacus and L. kharazii but differing from the closely related L. punctulatus , since the spermatheca in the latter species short and almost straight i.e. not evenly curved.
Remarks: This species has a wide distribution in the eastern parts of the Palaearctic region from Russia, West Siberia (Ural) to Mongolia, South Korea and Jilin, Liaoning (new record) and Heilongjiang (new record) Provinces of NE China.
