Abstract

Five new species of mimetid spiders from China are described: Mimetus subulatus n. sp., M. clavatus n. sp., M. dentatus n. sp., M. niveosignatus n. sp. and M. uncatus n. sp. The phylogenetic placement of these new species is inferred based on a cladistic analysis of an expanded version of the morphological dataset of Benavides and Hormiga (2020). The new species form a clade that can be distinguished from other Mimetus species by the presence of a subtegular apophysis between paracymbium and subtegulum, pilose cuticular projections on the membranous part of the conductor in the male palp and by a bicameral structure of the spermathecae in females. The new species are part of a clade that includes Mimetus syllepsicus Hentz, 1832, the type species of the genus. The genus Mimetus as currently circumscribed is not monophyletic, as the clade that includes all the Mimetus species also includes the genera Australomimetus Heimer, 1986 and Anansi Benavides and Hormiga, 2017, corroborating the results of Benavides and Hormiga (2020).
