A revision of the spider genera Drassodes and Tivodrassus (Araneae, Gnaphosidae) in North America. American Museum novitates ; no. 2593

Abstract

"Seven North American species of Drassodes and four of Tivodrassus are diagnosed and described. The usefulness of various genitalic characters for species discrimination in Drassodes is discussed. Five new species are described: D. mirus from the Rocky Mountains, D. angulus from California, and T. pecki, T. reddelli, and T. farias from Mexico. Drassodes saccatus (Emerton) is removed from the synonymy of D. neglectus (Keyserling) and considered a valid species. Five specific names are newly synonymized: D. phanus (Chamberlin) and D. yavapainus (Chamberlin), both with D. gosiutus Chamberlin; and D. centralis F.O.P.-Cambridge, D. celes Chamberlin, and D. robinsoni Chamberlin, all with D. saccatus (Emerton). The males of D. louisianus Roddy and T. ethophor Chamberlin and Ivie are described for the first time. Drassodes perditus Banks is transferred to Herpyllus"--P. [1].
