Four new generic and 14 new specific synonymies in Pholcidae, and transfer of Pholcoides Roewer to Filistatidae (Araneae)

摘要

The diversity of Neotropical pholcids is extraordinary, but our knowledge about this diversity is still fragmentary (Huber 2000). This is especially true at the level of species, where many dozens, more probably hundreds, of species remain undescribed. Evidence for this high number comes from regional surveys that yielded dozens of species within relatively limited geographic areas (e.g. Silva 1996; Florez 1996), and from the low degree of species overlap between localities (e.g. in the Brazilian Atlantic Forest, B. A. Huber, unpublished data). Venezuela may well be among the nations with the highest diversity, and the recent increase in genus and species numbers partly reflects this situation.
