Clubionid spiders from Xishuangbanna, Yunnan Province, China are studied. A total of seven genera and 13 species have been found, including two new genera with one new species each, i.e., Ramosatidia Yu & Li, gen. nov., with R. situ Yu & Li, sp. nov. (male female) as the type species and Sinostidia Yu & Li, gen. nov., with S. shuangjiao Yu & Li, sp. nov. (male female) as the type species. Five additional new species are Sinostidia dujiao Yu & Li, sp. nov. (male female), Matidia xieqian Yu & Li, sp. nov. (male female), Nusatidia changao Yu & Li, sp. nov. (male female), N. mianju Yu & Li, sp. nov. (female), and N. subjavana Yu & Li, sp. nov. (female). The following genera and species are reported from China for the first time: Malamatidia Deeleman-Reinhold, 2001, Pteroneta Deeleman-Reinhold, 2001, Malamatidia zu Jager & Dankittipakul, 2010, Nusatidia aeria (Simon, 1897), N. camouflata Deeleman-Reinhold, 2001, Porrhoclubiona pteronetoides (Deeleman-Reinhold, 2001), and Pteroneta ultramarina (Ono, 1989). Malamatidia christae Jager & Dankittipakul, 2010 syn. nov. is a junior synonym of Malamatidia zu. Nusatidia rama Deeleman-Reinhold, 2001 syn. nov. is synonymised with N. aeria (Simon, 1897).

Clubiona Latreille, 1804, the largest genus in family Clubionidae, currently includes 495 species worldwide with 126 species from China (Li & Lin 2016; World Spider Catalog 2018). Due to the high diversity in Clubiona, several subgenera and species-groups have been proposed (Wang et al. 2015). While there is no agreement on the limits of most species-groups of Clubiona (Deeleman-Reinhold 2001), the corticalis-group has been widely considered as putatively monophyletic. The group presents a distinct set of characters (Mikhailov 1995; Deeleman-Reinhold 2001; Liu et al. 2016) and the species composition of the core-group is relatively stable (Mikhailov 1995; Deeleman-Reinhold 2001; Dankittipakul & Singtripop 2008; Wu et al. 2015). At least two generic names are available for the corticalis-group, Atalia Thorell, 1887 and Paraclubiona Lohmander, 1944 (Mikhailov 2012). Spiders of the corticalis-group are well studied in China and several new species have been described in recent years (Yu et al. 2012; Zhu et al. 2012; Wang et al. 2015; Wu et al. 2015; Liu et al. 2016; He et al. 2016). Up to now, the Clubiona corticalis-group has more than 28 Chinese species (Wang et al. 2015; Wu et al. 2015; Liu et al. 2016; He et al. 2016; Yu et al. 2017), making it one of the most well known clubionid groups in China. While examining spiders collected from Guizhou Province, China, we came across some specimens from the Clubiona corticalis-group, which are described here as belonging to two new species.

A further study of the spider genus Pseudopoda Jäger, 2000, from Honghe Hani and Yi Autonomous Prefecture, Yunnan, southwest China, is presented. A total of six species are here addressed based on morphology and five methods of molecular species delimitation, increasing the number of known species of the genus in this area from 10 to 13. They comprise three new species, namely P. xiaozhua J. Zhang, H. Yu & Y. Zhong, sp. nov. (♂♀), P. yangae J. Zhang, H. Zhang & Y. Zhong, sp. nov. (♂♀), and P. ying J. Zhang, H. Zhang & Y. Zhong, sp. nov. (♂), and three known species: P. huanglianensis Zhang, Jäger & Liu, 2023, P. mamillaris Zhang, Jäger & Liu, 2023, and P. oliviformis Zhang, Jäger & Liu, 2023. The males of the three known species are described for the first time. Detailed descriptions, diagnoses, photographs of the six species, and a distribution map for all 13 Pseudopoda species in Honghe Prefecture are provided. The DNA barcodes of the six species were obtained for species delimitation, sex matching, and future use.

The Clubiona zilla-group is a relatively small species group, distributed exclusively in East Asia, with only three species clearly documented so far. Clubiona hooda Dong & Zhang, 2016, which was previously placed in the C. trivialis-group, is assigned to the C. zilla-group in the present paper. A new spider of the C. zilla-group from Jiugong Mountain in China is described under the name of C. jiugong sp. nov. Detailed descriptions and photographs of the new species are provided.
