Type material

(5 ♂♂, 3 ♀♀). HOLOTYPE, ♂, labelled as follows: (p) [Guanxi,CHINA], “locality in Chinese characters”, 25.V.1996, S. Uéno leg. / (p) ab. Liangshui 1710 m, Mt. Miao’ershan, Xing’an Xian. / red label (p) HOLOTYPE Lasinus sinicus sp. n., Bekchiev, Hlaváč & Nomura det., 2013. (NSMT). PARATYPES: 1♂: China, Vill, 86, Gansu: Mrijishan (h), 1000 m, Rougemont: 1 ♂, 2 ♀♀: same data as holotype, but specimens collected on 26.V.1996; 1 ♂, 1 ♀: China, Shaanxi, Nanwutaishan, 4.04.03, leg. Rougemont; 1 ♂: China, W Hubei, 21.VI–13.VII, Guanmenshan-1500 m, pit fall traps, 31.45N, 110.4E, leg. Jaroslav Turna, 2003. All paratypes bear the following red label: (p) PARATYPE Lasinus sinicus sp. n. Bekchiev, Hlaváč & Nomura det., 2013. (NSMT, MCSN, PCPH).
Description. Body (Fig. 4) bicolored, head, pronotum and abdomen almost black, elytra reddish-brown, maxillary palpi yellow, length 3.25–3.50 mm.
Head elongate, about 1.15 times longer than wide, slightly longer than pronotum; median sulcus absent along whole length of head. Genae simple, lacking protuberances.
Antennae long about 2.10 mm; scapes long, about 4 times longer than pedicels; pedicels shortest, 1.25 times shorter than antennomeres III; antennomeres III, IV, VII and VIII subequal in length, slightly shorter than V and VI; antennomeres XI 0.71 times longer than wide only slightly enlarged on the apex of antennomeres in male, in female unmodified; X 0.85 times longer than wide; XI 0.66 times longer than wide.
Pronotum about as long as wide, wrinkly, gibbose, with prominent lateral swellings before lateral foveae (Fig. 9); lateral and median setose foveae well-defined; median sulcus present only on disc, not originates from median fovea, very short and fine, largely separated from anterior margin of pronotum.
Legs long and slender; protrochanters with small apical spine; profemora with small spine in middle; mesotrochanters at apex with small median spine (male) or two (female) spines; mesofemora with small spine at basal third.
First visible abdominal tergite (IV) glabrous, very long, about 3.50 times longer than second (V); basal carinae very short, distance between carinae about 0.5 of maximal tergal width. Aedeagus (Fig. 22) 0.66 mm long; median lobe weakly narrowed apically, with short and very large apical lobe; endophallus with one large, bifid spine and one lamella; lamella large, with dentation on inner left part; parameres short and slender, not overlapping apical lobe.

Differential diagnosis

Lasinus sinicus is close to Lasinus mandarinus by the similar shape of the pronotum with prominent lateral swellings before the lateral foveae. They can be separated from it by the proportion of antennomere X which is almost as long as wide in Lasinus sinicus.

Etymology

The specific name is derived from China, where the species was discovered.

Distribution

China (Guangxi, Gansu, Shaanxi, Hubei)
