Três novas espécies sul-americanas de Cryptachaea e acréscimos taxonômicos em Achaearanea (Araneae, Theridiidae)

Abstract

ABSTRACT. Three new South American species of Chryptachaea and taxonomic additions in Achaearanea (Araneae, Theridiidae).

Twelve new Neotropical species of the spider genusCryptachaea(Araneae: Theridiidae)

“…Cryptachaea is closely related to Achaearanea , Hentziectypus Archer 1946 andParasteatoda Archer 1946 but can be distinguished from these genera by its male palp with a short to medium embolus, which is not articulated and not supported on the back of the cymbium; the base is fused to the median apophysis lodged in the cymbial hood (Levi 1955;Agnarsson 2004;Yoshida 2008;Buckup et al 2012). The epigynum of Cryptachaea has simple, uncoiled ducts leading to a pair of simple subcircular spermathecae and a slightly sclerotized plate.…”

“…The epigynum of Cryptachaea has simple, uncoiled ducts leading to a pair of simple subcircular spermathecae and a slightly sclerotized plate. The species of Cryptachaea lack the theridiid tegular apophysis, and as other members of the subfamily Theridiinae, also lack a colulus (Agnarsson 2004;Buckup et al 2012). In this paper we describe and illustrate twelve new species of Cryptachaea from Peru, Bolivia, Argentina, and Brazil.…”
