| 摘 要： | 由于蜘蛛身体表面所覆盖的体壳较薄，通常保存为化石的几率较小，因此，蜘蛛化石是一类较为稀有的化石。热河生物群中的蜘蛛化石迄今尚未进行过系统描述。本文报道了属于Araneidae Leach，1819(园蛛科)、Gnaphosidae(平腹蛛科)和Theidiidae Sundeva1833(球腹蛛科)6个蜘蛛新种：Araneus liaoxiensis sp．nov．，A．aethus p．nov．，A．reheensissp．nov．，A．beipiaoensis sp，nov．，Gtuzphosq liaoningensiss p．nov．和Theridion atalus sp．nov．；以及蟹奴幼虫的一个化石新属种Mesosacculina papposa gen．etsp．nov．。这些化石均采自辽西北票黄半吉沟义县组下部(晚侏罗世-早白垩世)。

| Abstract: | As spiders have thinner carapace, it is usually hard to be fossiliferous for the spiders. Therefore, the spider fossils are rare in geological record. Particularly, there has been no any paper reporting systematically the spider fossils in the Jehol Biota. In this paper, six new species of fossil spiders and a new taxa of sacculinidae fossil are described, including Araneus liaoxiensis sp. nov., A. aethus sp. nov., A. rehensis sp. nov., A.beipiaoensis sp. nov.; Gnaphosa liaoningensis sp. nov., Theridion atalus sp. nov. ; Mesosacculina papposa gen. et sp. nov. All the fossils are collected from the lower Yixian Formation(Upper Jurassic-Lower Cretaceous)in Huangbanjigou , Beipiao, Western Liaoning, China. |
