Abstract

Anyphaenidae includes 58 genera and 614 species of small to medium sized spiders, which normally inhabit arboreal environments. It is divided in Amaurobioidinae and Anyphaeninae subfamilies. Amaurobioidinae is distinguished by a tracheal spiracle closer to spinnerets than the epigastric region, and male palpus with an exclusive hyaline triangular area on tegulum. This subfamily exhibits 171 species distributed through the Americas. On the other hand, Anyphaeninae is diagnosed by chelicerae with more than four denticles on the retromargin, tracheal spiracle approximately on the middle of the venter, or between venter and epigastric sulcus; and is composed by 443 species widely distributed in the Americas, Paleartic and Oriental regions, and Polynesia. Anyphaeninae is a part of Dionycha, a highly diverse clade, with more than 15 families. In this project, we propose to continue the work on the phylogeny of the subfamily Anyphaeninae, improving the relationships we currently have within the group, and expanding the sample to genera with great diversity, such as Teudis, Katissa, Aysha, Hatitia and Pippuhana. Only a few phylogenetic hypothesis are available for the species of these genera and, therefore, they constitute a good study subject, as there is wide diversity and specimens available in Brazilian collections.
