Análise filogenética molecular das aranhas-caranguejo do gênero Misumenops Pickard Cambridge, 1900 - com a revisão do gênero Runcinioides Mello Leitão, 1929 (Araneae, Thomisidae)

Abstract

The family Thomisidae Sundevall, 1833 is consists of 2163 species distributed in 170 genera. Spiders of this family can be easily recognized by their legs I and II much larger and more robust than the others and by their lateral eyeslocated in tubercles. Thomisidae is divided into six subfamilies, including Misumeninae, the focus of this work. A molecular phylogeny of the genus Misumenops (chapter 1) and a taxonomic review of the genus Runcinioides (chapter 2) were carried out, both belonging to this subfamily. The Misumenops phylogeny showed that the genus isn’t monophyletic. The results also demonstrate that Old World species currently lodged in Misumenops should be transferred from the genus. The genus Runcinioides is revised, including the redescription of R. argenteus Mello-Leitão, 1929 and R. litteratus (Piza, 1933). The male of R. litteratus is described and illustrated for the first time and Misumenops paranensis (Mello-Leitão, 1932) is here considered a junior synonym of R. argenteus. The known geographic distribution of both species is expanded with the inclusion of new occurrence data. Runcinioides pustulatus Mello-Leitão, 1929 and Runcinioides souzai Soares, 1942 are not related to the other species of the genus, and provisionally considered as incertae sedis.
