Diagnosis.

The species can be easily distinguished from other species from southwest China by the abdominal tergites III-VI without a triangular, mediobasal, golden tomentose patch. In general appearance, T. velutinus is most similar to T. formosanus, but may be distinguished from the nominate ssp. of the latter by its smaller body size and paler mid and hind legs, and from T. formosanus flavipes by the dark antennae.

Distribution.

China (Yunnan), Myanmar.
