Previous issue date: 2015-03-16 / Conselho Nacional de Pesquisa e Desenvolvimento Cient?fico e Tecnol?gico - CNPq / This work is a cladistic study of Philodromidae Thorell, 1870 at genera level. The family currently have 549 species in 30 genera. Its distribution covers the temperate and tropical regions. Although many authors have studied the family and proposing a systematic classification, no cladistic analysis yet studied the internal relations of the family with a wide sampling of genres. This study aims to analyze the relationship between the genera of Philodromidae and test its monophyly. In the analysis were included 73 species, with representatives of 22 genera of the 30 total family genera and seven species from four families included as outgroups, which were respectively Salticidae, Thomisidae and Sparassidae with two species and representatives for rooting was selected one spiceie of Selenopidae. Where analyzed 130 characters somatic at 80 terminals via heuristic search with equal weighing of characters. The analysis resulted in 61 maximally parsimonious trees of 720 steps, with equal weights. The results at the two analyses have found thath the family is monophyletic. The analysis also indicated three groups of genres that are proposed in this study as subfamilies: Pedinopisthinae, Thanatinae and Philodrominae. Two subfamilies (Thanatinae and Philodrominae) partially match tribes previously proposed in other studies. Many of the diagnostic characters of the show are homopl?sicos genres. Cleocnemis and Philodromus shown to be paraphyletic and some monotypic genera were sinonimizados. This result allowed the development of a dichotomous key to genus, which is accompanied by the diagnosis and illustrations of the genera and species used in cladistic analysis. / Este trabalho ? um estudo clad?stico de Philodromidae Thorell, 1870 ao n?vel de g?nero. A fam?lia atualmente agrupa 549 esp?cies em 30 g?neros. Sua distribui??o abrange as regi?es temperadas e tropicais. Apesar de v?rios autores terem estudado a fam?lia propondo uma sistem?tica, nenhuma an?lise cladistica at? o momento estudou as rela??es internas da fam?lia com uma amostragem ampla dos g?neros. O presente trabalho visou analisar as rela??es entre os g?neros de Philodromidae. Na an?lise foram inclu?das 73 esp?cies, com representantes de 22 g?neros, dos 30 g?neros da fam?lia, e sete esp?cies de quatro fam?lias inclu?das como grupo externo, sendo elas respectivamente Salticidae, Thomisidae e Sparassidae com duas esp?cies representantes de cada fam?lia. Para o enraizamento foi selecionado uma esp?cie de Selenopidae. Foram analisados 130 caracteres som?ticos em 80 terminais atrav?s de busca heur?stica com pesagem igual dos caracteres. A an?lise resultou em 61 ?rvores maximamente parcimoniosas de 720 passos, com pesos iguais dos caracteres. Os resultados recuperam a monofilia da fam?lia. A an?lise tamb?m indicou tr?s agrupamentos de g?neros que s?o propostos neste estudo como subfam?lias: Pedinopisthinae, Thanatinae e Philodrominae. Duas subfam?lias (Thanatinae e Philodrominae) correspondem parcialmente a tribos propostas anteriormente por outros autores. Muitos dos caracteres diagn?sticos dos g?neros demonstram serem homopl?sicos. Cleocnemis e Philodromus demonstram ser parafil?ticos e alguns g?neros monot?picos foram sinonimizados. Este resultado permitiu a elabora??o de uma chave dicot?mica ao n?vel de g?nero, que ? acompanhada da diagnose e ilustra??es dos g?neros e das esp?cies que foram utilizadas na an?lise clad?stica.
