A revision of the American spiders of the family Atypidae (Araneae, Mygalomorphae). American Museum novitates ; no. 2704

Abstract

"The eight known New World species of Atypidae are diagnosed, described, and assigned to two genera on the basis of genitalic and somatic characters. Only one American species, Atypus snetsingeri Sarno, belongs to the Holarctic genus Atypus Latreille. The nominal species Atypus abboti (Walckenaer), A. rufipes Latreille, A. bicolor Lucas, A. milberti (Walckenaer), and A. niger Hentz are transferred to the endemic Nearctic genus Sphodros Walckenaer. Sphodros bicolor and S. milberti are newly synonymized with S. rufipes. Four new species are described: S. paisano from Texas and Tamaulipas, Mexico; S. fitchi from Nebraska, Kansas, Oklahoma, and Arkansas; S. atlanticus from Virginia, Illinois, North Carolina, and Georgia; and S. coylei from South Carolina"--P.
