Europe vs. China: Pholcus (Araneae, Pholcidae) from Yanshan-Taihang Mountains confirms uneven distribution of spiders in Eurasia

(1999), who published the first English book on Chinese spiders, reported 2 361 species in 450 genera from 56 families, while Li (2020) reported 5 084 species in 809 genera from 69 spider families. [...]we predict that the number of spider species in China will increase significantly in the coming years, and that the number of spider species in China is much higher than that in Europe (Li et al., 2021; Yao et al., 2021). Pholcus Walckenaer, 1805 of the family Pholcidae C.L. Koch, 1850 contains 362 species, most of which are from the Northern Hemisphere, including 15 from Europe (Nentwig et al., 2022) and 134 from China (Li, 2020). [...]in a single 16-day expedition in the YanshanTaihang Mountains, we discovered 13 species new to science. [...]a large amount of spider diversity in China is yet to be discovered, consistent with recent studies on other spider taxa in China (Li et al., 2021; Liu et al., 2022; Yao et al., 2021).
