A SURVEY OF THE HOLARCTIC LINYPHIIDAE (ARANEAE),A REVIEW OF THE ERIGONINE GENUS ZORNELLA JACKSON, 1932

摘要

The Holarctic erigonid genus Zornella has been surveyed. Four species are recognized in this genus, two Palaearctic: Z.cultrigera(L.Koch,11879) & Z.orientalis sp.nov., and two Nearctic: Z.armata(Banks, 1906) & Z.cryptodon Chamberlin,1920.It is demonstrated that neither nearctic species is conspecific with Z.cultrigera as was thought by Holm and other authors. Z.orientalis sp.nov. is described from northeastern Siberia. All of the species are illustrated and their distributions mapped.
