(Fig. 7)

Material examined. (10 ♂♂, 26 ♀♀). 3 ♂♂, 26 ♀♀, labeled ‘ China: Guangxi, Xing’an County (※aeA), Mao'er Shan (aAM), 25°52’27’’N, 110°24’44’’E, beech forest, mixed leaf litter, humus, sifted, 1940 m, 29.vii.2014, Peng, Song, Yu & Yan leg.’ (SNUC); 1 ♂, also from Mao'er Shan, 25°53’20’’N, 110°25’53’’E, 2000–2100 m, mixed litter, sifted, 22.vii.2012, Hu & Song leg.’ (SNUC); 1 ♂, also from Mao'er Shan, 25°52’31’’N, 110°24’54’’E, 1950–2000 m, mixed litter, sifted, 23.vii.2012, Hu & Song leg.’ (SNUC); 3 ♂♂, also from Mao'er Shan, ‘ 11.vii.2011, 2000 m, W.J. He & L. Tang leg.’ (SNUC); 2 ♂♂, labeled ‘ China: Guangxi, Wuming County (AdA), Daming shan (⋏℉M), 23°28’44’’N, 108°26’06’’E, mixed leaf litter, sifted, 1500 m, 29.vii.2012, Jia-Yao Hu leg.’ (SNUC).

Remarks. Males of the population from Guangxi (Fig. 7 A) have the antennomere XI with moderately prominent disc-like protuberance near base, protibiae with a small apical protuberance (Fig. 7 D), the mesotibia with a curved apical protuberance (Fig. 7 E), the abdominal sternite VII are modified (Fig. 7 F, 7G), with the apical lamina transverse, pointed at apex of lateral margin. and the aedeagus with the right paramere curved mesally, the internal sac bearing many small sclerotized spines, lacking a hairy sclerite. All these characters are similar to those of T. punctifrons Löbl, Kurbatov & Nomura, 1998, but considering of the large distributional disjunction of these two population (ca. 960 km), the identity of the specimens from Guangxi remains uncertain, pending a future examination of the male type specimen of T. punctifrons.
