Abstract The family Amaurobiidae includes 738 species, distributed in 74 genera characterized by the presence of dorsal and retrolateral apophysis on the male palpal tibia and a divided cribellum. Although traditionally considered closely related to Stiphididae Dalmas, the relationships between Amaurobiidae and the remaining spider families are still poorly known. The first attempt of a suprageneric classification for Amaurobiidae genera divided the family into nine subfamilies, of which only four are currently considered valid: Altellopsinae Lehtinen, Amaurobiinae Thorell, Coelotinae F. O. P. Cambrigde and Macrobuninae Petrunkevitch. Macrobuninae includes 71 species distributed in 19 genera, of which 12 are Neotropical, three Holartic, three Afrotropical and one Afrotropical and Neotropical. The relationships between Macrobuninae genera are still poorly known, but the inclusion of some species in more ample cladistic analysis suggests that the subfamily is paraphyletic. The aim of this study is to test the monophyly of Macrobuninae and elucidate the relationships between it's genera, based on a cladistic analysis of morphological data. In Addition,we are going to present detailed descriptions on the old and new Macrobuninae genera found during this study. | |
