Extraordinarius gen. nov., a new genus of Sparianthinae spiders (Araneae: Sparassidae) from southeastern Brazil

Abstract

A new genus of Sparianthinae, Extraordinarius gen. nov., is proposed to include the type species, Extraordinarius andrematosi sp. nov. (marte vênus), from São Paulo, E. brucedickinsoni sp. nov. (marte vênus), from Minas Gerais and Espírito Santo, and E. klausmeinei sp. nov. (marte) and E. rickalleni sp. nov. (marte vênus), from Espírito Santo. The genus is remarkable in that it is the only Neotropical genus of Sparianthinae with a large, sclerotized, Z-shaped conductor in the male palp and represents the southernmost record for the subfamily in the region. A distribution map is provided for all known species of the genus.
