Notes on three poorly known Arctosa species from China (Araneae: Lycosidae)

摘要

Three species of the genus Arctosa are revised and their relationship with A. cinerea, the type species of the genus, is discussed. Arctosa binalis Yu & Song, 1988 is a junior synonym of A. depectinata (Bosenberg & Strand, 1906). Males of Arctosa gougu Chen & Song, 1999 and Arctosa vaginalis Yu & Song, 1988 are described for the first time. All specimens examined were collected from the Yunnan Province, China. Morphological illustrations, photos, descriptions and SEM photographs of the male bulbus ofall species are given. Stridulatory files on chelicerae in Lycosidae are reported for the first time.
