Review of the Southern American spid genus Platnickia (araneae, zodariidae)

摘要

Although only two species have been assigned to the temperate South American zodariid genus Platnickia Jocque, the fauna is actually more diverse. The type species, P. elegans (Nicolet), is widespread in Chile, from Coquimbo south to Chiloe, and in adjacent Argentina, whereas P. bergi (Simon) is known only from the far southern tip of the continent: Magallanes in Chile, Tierra del Fuego in Argentina, and the Falkland Islands. Both species are redescribed on the basis of newly collected material. Three new species are described: P. roble from Nuble, Chile; P. wedalen, found in southern Chile, from Cautin to Aisen, as well as adjacent Argentina and the Falkland Islands, and P. bolson, known only from Llanquihue, Chile, and Rio Negro, Argentina.
