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.

Four species of spider genus Cheiracanthium C. L. Koch, 1839 are reported from Jinggang Mountains, Jiangxi Province, China. Two of them are described as new to science: C. auriculatum sp. n. (♀♂) and C. echinulatum sp. n. (♂). Cheiracanthium taiwanicum Chen, Huang, Chen & Wang, 2006 is recorded from Mainland China for the first time. Cheiracanthium zhejiangense Hu & Song, 1982, the most similar species to C. auriculatum sp. n., is a newly recorded species of Jiangxi Province. Detailed descriptions, diagnoses, and photographs of the two new species are given. Cheiracanthium taiwanicum and C. zhejiangense are also illustrated.

In the present paper, a worldwide checklist of Clubiona japonica-group spiders is provided based on published literature and authors’ collections. A new japonica-group species, Clubiona grucollaris sp. n. (♀♂) from Guizhou Province and Hainan Island of China is diagnosed, described, and illustrated. A distribution map of this species is given.

The representation of the genus Pristidia Deeleman-Reinhold, 2001 in China is here established in two species: Pristidia cervicornuta sp. nov. from Hainan Province and P. ramosa Yu, Sun & Zhang, 2012, which is here considered a senior synonym of Clubiona expansa Huang & Chen, 2012. A key to all Pristidia species and a distribution map of the Chinese species are given.
