  Beneath the surface: A new northern species of Trogloraptor (Araneae: Trogloraptoridae), genetic diversity and natural history Abstract We present a morphological description of a recently discovered species of spider in the family Trogloraptoridae from the Columbia River Gorge in northwestern Oregon. The family was previously monotypic (Trogloraptor marchingtoni) and only known from populations near the southwestern Oregon—northern California border. Trogloraptor tulishpun sp. nov. retains the key family synapomorphy, distinctive subsegmented raptorial tarsi, and an oblique membranous division of the basal segment of the anterior lateral spinnerets. Trogloraptor tulishpun is distinguished from T. marchingtoni by its color pattern, clypeal height, vulvar and palp structure. We have found T. tulishpun in four localities in the Columbia River Gorge, which show little mitochondrial sequence divergence from one another, but are highly genetically distinct from T. marchingtoni.

A new species in the mygalomorph trapdoor spider genus Nemesia Audouin, 1826 (Araneae: Mygalomorphae: Nemesiidae) from Italy, with notes on Nemesia taxonomy

Abstract

A new species in the mygalomorph trapdoor spider genus Nemesia, Nemesia bosmansi sp. nov., is described from central-western Italy. The spiders studied and described here were all collected in June 2002 by pitfall trapping in sandy dunes of the Parco Nationale del Circeo (Lazio). Additional information on the general state of Nemesia taxonomy is also provided.
