The araneid spider genus Alpaida O.P.-Cambridge, 1889 has, until now, 148 described species (WSC 2015). The males of A. nigrofrenata (Simon, 1895), A. machala Levi, 1988, and A. cisneros Levi, 1988 are described here for the first time. A. moka Levi, 1988, based on female specimens, is synonymized with A. xavantina Levi, 1988, based on the study of specimens of both sexes. I.L.F. de Magalhães (MACN) is thanked for reviewing an early revision of this manuscript. We also thank to M. Machado…

A new species of Alpaida (Araneae, Araneidae) from Southeastern Brazil

This species seems to be related to Al paida scriba and Alpaida alticeps due to similar body shape and color, but is easily distinguished by the very elongated median apophysis, the massive lobe of tegulum and the hooked paracymbium of male palp.
