Abstract
"The North American Rachodrassus (three species), Sosticus (three species), and Scopodes (11 species) are diagnosed and described. Drassyllochemmis Gertsch and Davis is transferred from the Clubionidae and synonymized with Rachodrassus; Sostogeus Chamberlin and Gertsch is synonymized with Sosticus. A cladistic analysis of Scopodes is presented, and it is suggested that Scopodes and and allied genera, together with the spiders currently placed in the Prodidomidae and Molycriinae (Clubionidae), form a monophyletic group characterized by a strongly procurved posterior eye row and enlarged anterior spinnerets. Seven new species are described: Rachodrassus exlineae from the southeastern United States, Sosticus californicus from California, and Scopodes kastoni, Scopodes bryantae, Scopodes rostratus, Scopodes santiago, and Scopodes tlacolula from the southwestern United States and Mexico. Echemus ochraceus F.O.P.-Cambridge is transferred to Scopodes. Scopodes pessimisticum (Chamberlin) is synonymized with Scopodes naturalisticum (Chamberlin). The male of Scopodes nesiotes (Chamberlin) and the females of Rachodrassus captiosus (Gertsch and Davis), Scopodes catharius Chamberlin, Scopodes cambridgei (Gertsch and Davis), Scopodes asceticum (Chamberlin), and Scopodes ochraceus (F.O.P.-Cambridge) are described for the first time"--P.
