Two new species of the spider genus Alpaida (Araneae: Araneidae) from restinga areas in Brazil

Abstract

ABSTRACT. Two new species of Alpaida O.P.-Cambridge, 1889 are described based on male and female specimens from seven restinga areas from northeastern to southern Brazil. Alpaida teresinha sp. nov., from Rio de Janeiro and Espírito Santo, differs from other species of the genus in the wider lobe of the conductor, the concave median apophysis and with the posterior lobe ventrally positioned, and the wrinkled distal projection of the terminal apophysis in males.Females can be recognized by having widely spaced epigynal lips and by the narrow epigynal notch in ventral view.Alpaida toninho sp. nov., from Bahia, Espírito Santo, Rio de Janeiro and Santa Catarina, can be distinguished by the round lobes of the terminal apophysis, and by the median apophysis with a distal lobe and a projection in males, and by the epigynum elliptical, with a short scape in females.

New species of Alpaida (Araneae, Araneidae) from Rondônia, Brazil

“…Since the revision, ten contributions were made to the taxonomy of the genus, including the transfer and redescription of Alpaida tullgreni (Caporiacco, 1955) (Levi, 1993), the description of five males and one female of species previously known only from one sex (Buckup & Meyer, 1993;Rodrigues & Mendonça, 2011), and the description of 12 new species (Abrahim & Bonaldo, 2008;Santos & Santos, 2010;Buckup & Rodrigues, 2011;Braga-Pereira & Santos, 2013;Deza & Andia, 2014;Dierkens, 2014;Saturnino et al, 2015). In this paper we described a new species of Alpaida based on both sexes.…”

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

“…After Levi's work, a handful of papers about the genus were published, adding 11 species and one subspecies to the genus (Levi, 1992;Buckup & Meyer, 1993;Abrahim & Bonaldo, 2008;Framenau et al, 2009;Santos & Santos, 2010;Buckup & Rodrigues, 2011;Rodrigues & Mendonça Jr, 2011;Braga-Pereira & Santos, 2013;Dierkens, 2014;Deza & Andía, 2014;Poeta &Lise, 2015 andSaturnino et al, 2015).…”
