The new species is similar to T. baishanzuensis sp. nov., but it can be easily recognized from latter by the bicolored femora. From other species of east and southeast China, it can be easily recognized by the bicolored abdomen. Description. The new species is similar to T. baishanzuensis sp. nov. in most aspects except for the following characters: abdominal tergites III-VII each with a longer and more distinct triangular, mediobasal, golden tomentose patch; femora each with median dark mark and apical dark mark, although the apical dark markings of the forelegs are less distinct. Male. Sternite VIII with medioapical emargination. Aedeagus (Figs 88 - 95 ) slender, median lobe gradually narrowed apicad with round apex in ventral view, apex of median lobe expanded dorsad in lateral view; paramere relatively long, apex wide and round with approximately 11 setae around the apical margin.

Distribution. China (Guangdong, Hunan, Guangxi, and Yunnan). Etymology. This species is named after its bicolored abdomen.
