Abstract

The spider genus Episinus Walckenaer, 1809 currently contains 66 species worldwide, mostly in warm temperate to tropical areas. This paper describes two new Chinese Episinus species: E. ornithorrhynchussp. nov. (♂♀) and E. papilionaceoussp. nov. (♀). We add these two new and one known Episinus species to the phylogenetic data matrix of Liu et al. 2016 and reanalyze the data. The new phylogeny recovers the monophyly of Episinus and supports its division into two groups, a finding also supported by morphology.
