Figs 10–11 , 14

Draconarius tortus Chen, Zhu & Kim 2008: 86 , figs 2–5 (♀); Jiang et al. 2017: figs 1–15 (Ƌ ♀); Zhu et al, 2017: 393, fig. 257 (♀).

Diagnosis. Males can be distinguished from the similar T. qixianensis sp. n. by the thin RTA, conductor pointed posteriorly with a lamella and a strong dorsal apophysis. From the similar T. liangensis sp. n. by the patellar apophysis with a pointed tip, narrow embolus, and the long lamella of the conductor. From the similar T. yumiganensis sp. n. by the lack of a spine next to the RTA, patellar apophysis with a pointed tip, and the cymbial furrow over 2/3 the length of the cymbium ( Fig. 10 B–C). Females can be distinguished from the similar T. yosiianus sp. n. by the wide and truncated epigynal teeth which are pointed anteriorly and spermathecae overlapped at their tip. From the similar T. liangensis sp. n. by copulatory ducts thin vs. wide ( Fig. 11 A–B).

Description. Cervical groove and radial furrows dark. All eyes absent. Leg yellowish. Abdomen grey. Male palp: patellar apophysis with pointed tip; VTA triangular; length of RTA about 1/3 the length of VTA; cymbial furrow about 2/3 the length of the cymbium; embolus beginning at 5 o’clock position; conductor with a blunt dorsal apophysis and a large lamella ( Fig. 10 A–C). Epigyne: atrium 2 times wider than long, located at posteriorly; teeth short, 4 times wider than length, spaced of each other by 3 widths; copulatory ducts convoluted with 7 coils; spermathecae spaced by 2 widths ( Fig. 11 A–B).
