On three new Euathlus tarantulas from Argentina and cladistic analysis of the genus
Journal of Arachnology 43(3):313-326. 2015.
Abstract
Three unknown species of <i>Euathlus</i> Ausserer 1875 (Araneae: Theraphosidae) are recognized and formally described. <i>Euathlus diamante</i> Ferretti sp. nov., <i>E. sagei</i> Ferretti sp. nov., and <i>E. tenebrarum</i> Ferretti sp. nov. are described from the Mendoza and Neuquén provinces of western Argentina. The cladistic analysis showed <i>Euathlus</i> as monophyletic supported by the following synapomorphies: i) male tibial apophysis with fused branches bases; ii) presence of a ventral spine on retrolateral branch of male tibial apophysis; iii) sternum longer than wide. According to this cladistics analysis, a tree topology of (<i>Homoeomma uruguayense</i> (Mello-Leitão 1946) (<i>Plesiopelma longisternale</i> (Schiapelli & Gerschman 1942) (<i>Grammostola anthracina</i> (C.L.
