Holotype.

Female (LH-2017-051), collected in Baishuwang Garden Roadside, Bayi Town, Linzhi City, Tibet, China, 29.6106N, 94.4040E, 2980 m a.s.l., 14 July 2017, collected by FX Liu, ZT Zhang, J Chen and J Liu (CBEE).

Paratypes.

3 females (LH-2017-046, LH-2017-048, LH-2017-050), collected at the same locality as the holotype (CBEE).

Diagnosis.

Females of C. linzhi sp. n. can be distinguished from those of the other Conothele species by an obviously large irregularly duct-like sigillum in the sternum center (Fig. 3C); by the terminal lobes of spermathecae hemisphere-shaped; by the distal part of stalks Z-shaped and tilted slightly anteriorly (Fig. 3G-J).
