Six new cave-dwelling species of Leptoneta (Arachnida, Araneae, Leptonetidae) from Beijing and adjacent regions, China

Six new leptonetid spiders of the genus Leptoneta from caves of Beijing, Hebei, and Henan, China are diagnosed, described and illustrated. They are: L. cornea n. sp., L. exilocula n. sp., L. foliiformis n. sp., L. setulifera n. sp., L. tianxinensis n. sp. and L. wangae n. sp. All the new species described in this study can be distinguished from other congener species by the spines on male palpal femur and tibia, the number of cheliceral teeth and the details of genitalia of both sexes. An identification key to currently known 25 Chinese Leptoneta species, except for L. arquata Song & Kim, 1991, is provided.
