Diagnosis.
The new species is similar to T. longling in the shape of bulb, the small dark spot on male epigastric region and the rugose sternal surface, but can be distinguished by the sternum with two clusters of short, thick setae on posterior part (Fig. 2 D View Figure 2 ) vs. lacking, but with many rows of small ridges ( Tong et al. 2019: fig. 13 E), the cymbium with two extremely long, flat setae (Fig. 4 A, C, E, H View Figure 4 ) vs. lacking ( Tong et al. 2019: fig. 14 A), and the anterior margin of female postgastric scutum smoothly curved (Fig. 6 A View Figure 6 ) vs. with a small notch at middle ( Tong et al. 2019: fig. 24 I).
