Introduction
The family Oonopidae Simon, 1890 includes 1893 extant species in 115 genera worldwide, mainly distributed in tropical regions (WSC 2023).Oonopid spiders are tiny, with a body size between 1.0 and 3.0 mm.They mainly inhabit leaf litter and similar habitats, such as woodrat nests, under rocks, or interstitially (Ubick and Dupérré 2017).
Currently, 125 oonopid species have been recorded in China, of which 37 species belonging to seven genera are known so far in Yunnan, China (Tong and Li 2015a, b;Liu et al. 2019;Sun et al. 2019;Tong et al. 2019Tong et al. , 2021;;Huang et al. 2021;WSC 2023).While studying new material we found two new species belonging to two genera that were not known previously from China; the two new species are described below.
