我们回顾了Oxysoma Nicolet蜘蛛属，它的大部分种类是智利和阿根廷南部温带森林特有的，并对7种蜘蛛进行了系统发育分析，其中3种是本研究中新描述的(均来自智利的Oxysoma Nicolet新种、O.kuni新种和O.losruiles新种)，以及其他107种Anyphaenidae的代表。提供了所有种的新的地理记录和分布图，并附有插图和回顾了该属和四个先前已知的种(O.startatum Nicolet，O.saccatum(Tullgren)，O.Longiventre(Nicolet)和O.itambezinho Ramirez)的诊断。使用分支系统学方法进行的系统发育分析是基于264个先前定义的特征加上从这项研究中产生的一个特征。这三个新种与Oxysoma long giventre有密切的亲缘关系，这四个种组成了我们定义的Oxysoma long giventre种群。系统发育分析没有检索到Oxysoma的单系性，应该在将来与Tasata属一起重新评估。
We review the spider genus Oxysoma Nicolet, with most of its species endemic from the southern temperate forests in Chile and Argentina, and present a phylogenetic analysis including seven species, of which three are newly described in this study (O. macrocuspis new species, O. kuni new species, and O. losruiles new species, all from Chile), together with other 107 representatives of Anyphaenidae. New geographical records and distribution maps are provided for all species, with illustrations and reviewed diagnoses for the genus and the four previously known species (O. punctatum Nicolet, O. saccatum (Tullgren), O. longiventre (Nicolet) and O. itambezinho Ramirez). The phylogenetic analysis using cladistic methods is based on 264 previously defined characters plus one character that arises from this study. The three new species are closely related with Oxysoma longiventre, and this four species compose what we define as the Oxysoma longiventre species group. The phylogenetic analysis did not retrieve the monophyly of Oxysoma, which should be reevaluated in the future, together with the genus Tasata.
