Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Alpaida venger sp. nov. is described based on males and females from Pedra Branca State Park, Rio de Janeiro, Brazil. This species seems to be related to Alpaida scriba (Mello-Leitão, 1940) and Alpaida alticeps (Keyserling, 1879) 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. Females have elongated epigyne as A. scriba, but can be distinguished by the wider lips and shorter scape.
