Abstract
The oldest known spider, from the Devonian (Givelian) of Gilboa. New York, is Atlercopus fimbriunguis (Shear. Sclden and Rolfc). parts of which were originally described as a trigonotarbid. possibly of the genus Gelasinotarbus. Previous reports of Devonian spider fossils, from the Lower Emsian of Alken-an-der-Moscl. Germany, and the Pragian of Rhynie. Scotland, are shown to be erroneous identifications. Atlercopus is placed as sister-laxon to all living spiders, on the basis of characters of the spinneret and the arrangement of the patella-tibia joint of the walking legs. A cladogram of the relationships of all pulmonate arachnids is presented. A pulmonate arachnid from Gilboa. related to Arancae and Amblypygi. is described as Ecchosis pulchribolhrium Selden and Shear, gen. ct sp. nov., and additional arachnid material is described.
