摘要

Spiders have become an important model to study the evolution of sociality, but a lack of their detailed natural history and taxonomy hinders broader comparative studies. Group-living crab spiders (Thomisidae) provide an excellent contrast to other social spiders since they lack a communal capture web, which was thought to be a critical factor in the evolution of sociality. Only three non-webbuilding crab-spider species are known to be subsocial or social, all of which belong to the genus Diaea Thorell, 1869. The aim of this study is to describe the social lifestyle of Xysticus bimaculatus L. Koch, 1867 for the first time. Furthermore, we present a detailed re-description of this species and discuss its taxonomic implications. Like other subsocial crab spiders, X. bimaculatus builds nests from tree leaves. Nests contain up to 38 spiders and sometimes several adult females, indicating the species may be at a transitory stage between subsociality and permanent sociality.

Koch，1867年的社会生活方式。第一次。此外，我们提出了对该物种的详细描述，并讨论了其分类学意义。像其他亚社会蟹蜘蛛一样，bimaculatus X.也从树叶上筑巢。巢中最多可容纳38只蜘蛛，有时还包括几只成年雌性，这表明该物种可能处于次社会和永久社会之间的过渡时期。
