The subspecies is most similar to T. velutinus from Yunnan and Myanmar, but can be easily distinguished by the usually black mid and hind tibiae and tarsi. Both differ from other species from east and southeast China in the abdominal tergites III-VI without triangular mediobasal golden tomentose patch.
