( Figs 1A–C , 5 )

Material studied. CHINA: Guangxi: 1 ♀, Xing’ an County, Mao’er shan N. R., 1550–1750 m, 24.VII.2012, Hu & Song leg. ( SNUC) .

Comment. The original description is based on two males. There were male species at that time, and the species was determined based on the characteristics of both sexes, but now because the male specimens are lost, only the female species remain, so the remaining label information cannot be entered. Comparing the holotype, this species is similar in general appearance and tergites characters to L. anatinum . And Mao’er shan N. R. and Anjiangping are only 63 kilometers apart in the north of Guangxi, so it is considered the same species. The previously unknown female sexual characters are as follows: posterior margin of tergite VIII ( Fig. 1A ) convex; posterior margin of sternite VIII ( Fig. 1B ) strongly convex and with moderately dense micropubescence; tergite IX ( Fig. 1C ) with median suture and long postero-lateral processes; tergite X ( Fig. 1C ) nearly reaching anterior margin of tergite IX ( Fig. 5 ). For illustrations of the habitus and the male sexual characters, see Li et al. (2013) .
