A checklist of spiders from Yongxing Island, South China Sea, with taxonomic notes on four species of goblin spiders.

A preliminary checklist of spiders of the Yongxing Island is provided, based on a short-term study undertaken in January 2008. A total of 23 species, belonging to 21 genera and 11 families, were recorded from the area, which forms baseline information of spiders of the Yongxing Island. Amongst these, Oonopidae, Pholcidae, Araneidae and Salticidae were found to have more species in the area. Brignolia parumpunctata (Simon, 1893), Opopaea apicalis (Simon, 1893), Opopaea deserticola Simon, 1891 and Xyphinus baehrae Kranz-Baltensperger, 2014 were firstly reported from China, for which we provide taxonomic description in this paper.
