description: <i>Otacilia lubrica</i> sp. nov. (光滑Dzḇü) Fig. 3 <b>Type material.</b> Holotype &amp;male; (CQCK-18-03): CHINA: Chongqing City, Chengkou County, Longtian Town, Wuli village (32°04.269′N, 108°39.914′E, 1286 m), 16 Mar. 2018, leg. Luyu Wang. Paratypes: 11&amp;male; 16&amp;female;, with same data as holotype; CHINA: 6&amp;male; 1&amp;female; (CQCK-18-02), Chongqing City, Chengkou County, Longtian Town, Wuli village, hillside behind primary school (32°03.726′N, 108°40.351′E, 1206 m), 16 Mar. 2018, leg. Zhisheng Zhang. <b>Etymology.</b> This specific name is derived from the Latin word “lubricus”, meaning smooth, referring to the smooth glossy texture of the carapace; adjective. <b>Diagnosis.</b> This new species resembles <i>O. fabiformis</i> Liu <i>et al.</i>, 2019, but the males can be distinguished from it by the long and transverse embolus (<i>vs</i> shorter and directed distally), the long and thin conductor (<i>vs</i> triangular), and the wide RTA and long DTA (<i>vs</i> thin RTA and DTA) (compare Fig. 3C–F with fig. 6B–E in Liu <i>et al.</i> 2019). Females differ from <i>O. fabiformis</i> by the globular glandular appendage (<i>vs</i> absent) and the large and globular spermathecae (<i>vs</i> small) (compare Fig. 3G–H with fig. 7B–C in Liu <i>et al.</i> 2019). <b>Description.</b> Male.
