A new genus of the spider family Deinopidae C.L. Koch, 1850 is described from Asia: Asianopis Lin & Li gen. nov., with A. zhuanghaoyuni Lin & Li sp. nov. as the type species. The new genus is divided into two species groups, of which the liukuensis-group includes two species: A. dumogae (Merian, 1911) sp. reval. comb. nov. (♀) and A. liukuensis (Yin, Griswold & Yan, 2002) comb. nov. (♂♀); and the zhuanghaoyuni-group comprises five species: A. celebensis (Merian, 1911) comb. nov. (♂), A. konplong (Logunov, 2018) comb. nov. (♂), A. wangi Lin & Li sp. nov. (♂♀), A. wuchaoi Lin & Li sp. nov. (♂♀), and A. zhuanghaoyuni Lin & Li sp. nov. All previously described species are transferred from Deinopis MacLeay, 1839. Deinopis scrubjunglei Caleb & Mathai, 2014 is treated as a junior synonym of Asianopis liukuensiscomb. nov.

Species of the spider family Hypochilidae Marx, 1888 from China are studied, including two known species and two new species of the genus Ectatosticta Simon, 1892. The new species are E. wukongsp. nov. (♂♀) from Sichuan and E. xuanzangsp. nov. (♀) from Tibet.

Abstract Two termitophilous tenebrionid genera, Nepaloplonyx Bremer, 2014 and Xenotermes Wasmann, 1896, are reported from mainland China for the first time. Nepaloplonyx yunnanensis Jiang, Wang & Wang, sp. nov. (Yunnan Province), Nepaloplonyx qiului Jiang, Wang & Wang, sp. nov. (Yunnan Province), and Xenotermes sp. (Yunnan Province) are described, figured and compared with their congeners. New distributional records for Ziaelas formosanus Hozawa, 1914 from Guangdong, Guangxi, Yunnan, and Jiangsu Provinces are provided. Biological information, collection data and distribution map of all four species are also provided.
