摘要

摘要我们描述了1869年美国乔治亚州沃克县的两个新的Nesticus Thorell。Nesticuslula sp.nov.是从Lookout山东部边缘的两个洞穴中已知的，N.cressleri sp.nov..是从鸽子山的三个洞穴中得知的。形态学和分子证据表明，与阿巴拉契亚山脉南部的其他雀巢相比，这两个物种具有独特性。Nesticus lula的眼睛缩小了，N.cresleri没有眼睛。这两个物种都值得保护，因为它们只分布在极为有限的少数几个地点。这项工作有助于我们了解格鲁吉亚的洞穴生物多样性和阿巴拉契亚山脉南部的雀巢辐射。

Two new Nesticus Thorell, 1869 (Araneae: Nesticidae) from caves in northwest Georgia, USA

Abstract. We describe two new Nesticus Thorell, 1869 from Walker County, Georgia, USA. Nesticus lula sp. nov. is known from two caves on the eastern edge of Lookout Mountain and N. cressleri sp. nov. is known from three caves on Pigeon Mountain. Morphological and molecular evidence indicates the distinctiveness of both species when compared to other Nesticus from the southern Appalachians. Nesticus lula has reduced eyes and N. cressleri is eyeless. Both species are of conservation concern, as they are known from only a handful of sites spanning extremely limited ranges. This work contributes to our understanding of cave biodiversity in Georgia and of the Nesticus radiation in the southern Appalachians.
