(Figs 2A, 3, 6)

Material studied. CHINA: Xizang: 1 ♂, 1 ♀, Dinggyê County, Zhêntang Town, Ganma Zangbo Valley , 27°51’50’’N, 87°24’24’’E, 2400 m, 28. VI .2021, Z. Peng leg. ( SNUC) .

Comment. The original description of L. biaculeatum is based on specimens from Nepal ( Assing 2012). The above specimens from Xizang are very similar to L. biaculeatum Assing, 2012 in general appearance (Fig. 2A) and aedeagal characters ( Fig. 3 ). The only difference found is a more acute ventral process of aedeagus. For illustrations of L. biaculeatum see Assing (2012: figure 109–112). Therefore, we consider it to belong to the same species. The above record from China represents a new country record ( Fig. 6 ).
