A list of 34 thomisid species belonging to 21 genera collected in Jangxi Province of China is provided. Five new species are described: Angaeus xieluae Liu, sp. nov. (♂♀), Lysiteles subspirellus Liu, sp. nov. (♀), Oxytate mucunica Liu, sp. nov. (♀), Pharta lingxiufengica Liu, sp. nov. (♀), Stephanopis xiangzhouica Liu, sp. nov. (♀). A new combination is proposed: Ebelingia forcipata (Song & Zhu, 1993) comb. nov. (ex. Ebrechtella Dahl, 1907). Previously unknown females of E. forcipata (Song & Zhu, 1993), Oxytate bicornis Liu, Liu & Xu, 2017, and Xysticus lesserti Schenkel, 1963 are described for the first time. Stephanopis O Pickard-Cambridge, 1869, a genus previously known from Australasia and South America, is recorded from the Asian mainland for the first time.
A new species, Chalcoscirtus sinevi sp. n., from the Altai Mountains (South Siberia) is described on the basis of both sexes. The new species is closely related to C. grishkanae Marusik, 1988 from North-Eastern Siberia and Transbaikalia, which is also illustrated. Molecular evidences supporting a separate species status of the new species are provided.
New records of 12 species found in Mongolia for the first time are provided. One of them -Dipoena yutian Hu et Wu, 1989 -previously known only from Xinjiang Province of China is illustrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
