A taxonomic revision and phylogenetic analysis of the spider genus Epicratinus Jocqué Baert, 2005 is presented. The phylogenetic analysis is based on a data set including 16 Epicratinus species plus 9 outgroups representing by five related zodariid gen-era and one of them considered most basal as the root. These taxa were scored for 49 morphological characters. Parsimony was used as the op-timality criterion and a sensitivity analysis was performed using different character weighting concavities. Five unambiguous synapomorphies support the monophyly of Epicratinus. Some internal clades within the genus are well-supported and their relationships are discussed. Epicratinus includes 16 species, all with males and females. A species identification key and distribution maps are provided for all. New morphological data are also pre-sented for five previously described species. All 16 species occur only in the New World. The following species are transferred to Epicratinus: E. perfidus (Jocqué Baert), comb. nov. from Tenedos; Epicratinus perfidus Jocqué Baert comb. nov. and newly synonymized with E. santacruz Grismado Izquierdo and this last species is treated as the junior synonym. Epicratinus petropolitanus (Mello-Leitão) has the male described for the first time. The following 11 species are newly described as new: E. zangief sp. nov.; E. pegasus sp. nov.; E. pikachu sp. nov.; E. stitch sp. nov.; E. ehonda sp. nov.; E. anakin sp. nov.; E. vader sp. nov.; E. omegarugal sp. nov.; E. zelda sp. nov.; E. dookan sp. nov. and E. mauru sp. nov., all from Brazil.
本文对蜘蛛属Epicratinus Jocqué & Baert, 2005进行了分类修订和系统发育分析。系统发育分析基于一个数据集,该数据集包括16种Epicratinus物种以及9个外类群,外类群由5个相关的球蛛科属代表,其中一个被认为是最基部的作为根。这些分类单元针对49个形态特征进行了评分。简约法被用作最优标准,并使用不同的特征加权凹度进行了敏感性分析。五个明确的共衍征支持Epicratinus的单系性。该属内的一些内部类群得到了很好的支持,并讨论了它们之间的关系。Epicratinus包括16个物种,均有雄性和雌性。为所有物种提供了物种鉴定检索表和分布图。还提供了五个先前描述物种的新形态数据。所有16个物种仅分布于新大陆。以下物种被转移到Epicratinus属:E. perfidus (Jocqué & Baert),组合新名,来自特内多斯岛;Epicratinus perfidus Jocqué & Baert,组合新名,新同义于E. santacruz Grismado & Izquierdo,最后这个物种被视为次异名。Epicratinus petropolitanus (Mello-Leitão)的雄性首次被描述。以下11个物种被新描述为新物种:E. zangief新种;E. pegasus新种;E. pikachu新种;E. stitch新种;E. ehonda新种;E. anakin新种;E. vader新种;E.omegarugal新种;E. zelda新种;E. dookan新种和E. mauru新种,均来自巴西。
