Lathrobium proprium Peng & Li, 2012 (Figs 2 A, 3)

Material studied (1 ♂, 4 ♀♀). China: 1 ♂, 4 ♀♀, Guangxi Prov., Xingan County, Mt. Maoershan, 25°54’N 110°27’E, alt. 1,550–1,750 m 24.vii.2012, Hu & Song leg. (SNUC).

Comment. The original description is based on a single male with a probably slightly damaged aedeagus (Peng et al. 2012). The species is most likely endemic to the Maoer Shan (Fig. 1). For illustrations of the habitus and the male sexual characters see Fig. 3 and Peng et al. (2012). The aedeagus and the previously unknown female sexual characters are as follows: aedeagus as in Figs 3G, 3H; ventral process asymmetric and distinctly angled subapically (lateral view); dorsal plate sclerotized and long; internal sac without sclerotized structures; posterior margin of female tergite VIII (Fig. 3A) moderately pointed at middle; female sternite VIII (Fig. 3B) longer than tergite VIII, apical margin broadly convex; female tergite IX (Fig. 3C) with short antero-median portion and with slender postero-lateral processes, median portion with median suture; female tergite X approximately five times as long as antero-median portion of female tergite IX (Fig. 3C).
