A survey of cheiracanthiid spiders (Araneae: Cheiracanthiidae) from Hainan Island, China

ABSTRACT

Six species in two genera of the family Cheiracanthiidae Wagner, 1887 are studied from Hainan Island, China, including two new species: Cheiracanthium bawanglingense sp. n. (♀♂) and Eutittha hainanensis sp. n. (♀). Cheiracanthium ningmingense Zhang and Yin, 1999 syn. n. is synonymised with C. exquestitum Zhang and Zhu, 1993, and C. adjacensoides Song, Chen and Hou, 1990 stat. resurr. (♀♂) is removed from synonymy with C. approximatum O. Pickard-Cambridge, 1885. Cheiracanthium insigne O. Pickard-Cambridge, 1874 (♀♂) and C. taegense Paik, 1990 (♀♂) are reported from Hainan Province, China, for the first time. Photos of habitus and genitalia and a distribution map of all species are given.
