A new species of the genus Phrurolithus (Araneae: Corinnidae) from Mt. Cangshan of Yunnan Province, China

摘要

A new species of the genus Phrurolithus belonging to family Corinnidae from Mt. Cangshan of Yunnan Province, China, is diagnosed, described and illustrated under the name of Phrurolithus cangshanensis sp. nov. The spider family Corinnidae currentlycontains 80 genera and 956 species in the whole world (Platnick 2009), and in terms of the number of described species, the family is the tenth among Araneae. At present ten genera containing 45 species of this family have been reported from China (Platnick 2009). The genus Phrurolithus C. L. Koch 1839, includes 69 described species (Platnick 2009); but as pointed out by Yin et al. (2004), "the richness is deceptive as most of the species are probably not closely related to the type species: P. festivus(C. L. Koch 1835)". The genus Phrurolithus is like a waste-basket, as many phrurolithine specimens have tibiae and metatarsi I, II with several pairs of spines, and if characters of a specimen do not fit those of known genera, it may be assigned to Phrurolithus. Though some of them have already been formerly reassigned to other genera, for example, Scotinella, Liophrurillus, Phrurolinillus and Otacilia, this genus remains in need of further research. Eventually, it may be split into several new generaor some species may be transferred to other known genera.
