Material studied. CHINA: Xizang: 2 ♂♂, Linzhi City, near Woluobangga village , 29°35’45’’N, 94°20’49’’E, alt. 3090 m, 04.VII.2018, Cheng, Peng & Shen leg. ( SNUC) .

Comment. The original description of L. excisissimum is based on specimens from Yunnan ( Assing 2012). The above record from Xizang is very similar to L. excisissimum Assing, 2012 in general appearance (Fig. 2C) and aedeagal characters ( Figs 1D–G ) and separated only by somewhat without yellowish spot in middle and faint reflex of elytra, consider of it as the same species. The above record from Xizang represents a new province record and extends the distributional range about 740 km northwestwards ( Fig. 8 ).
