Abstract
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.
Highlights
The first revision of the genus was carried out by Levi (1988), with the redescription of 40 species that were previously misplaced in several other genera within Araneidae, alongside the description of 94 new species
The spider fauna of the area has recently been explored in a standardized taxonomic survey, during the master studies of the first author, revealing a total of 371 species or morphospecies, where Araneidae was the second richest family with 47 species, seven of which belonging to the genus Alpaida
Data obtained from a spider inventory in Pedra Branca State Park revealed a new species: Alpaida venger sp. nov., described and illustrated here based on both sexes
