On the Peruvian Erigone palustris Millidge, 1991, with notes on the psychrophila-species group (Arachnida: Araneae)

摘要

The Peruvian high-altitude spider species Erigone palustris Millidge, 1991, a member of the psychrophila-species group, is redescribed and illustrated. This species is very similar to the northern European hypoarcto-boreal E. svenssoni Holm, 1975, different only in a few minor details of the male palp. A list of the psychrophila-species group is presented and its biogeography is discussed.
