Data from: The velvet spiders: an atlas of the Eresidae (Arachnida, Araneae)

The family Eresidae C. L. Koch, 1850 is reviewed at the genus level. The family comprises nine genera including one new genus. They are: Adonea Simon, 1873, Dorceus C. L. Koch, 1846, Dresserus Simon, 1876, Eresus Walckenaer, 1805, Gandanameno Lehtinen, 1967, Loureedia gen. n., Paradonea Lawrence, 1968, Seothyra Purcell, 1903, and Stegodyphus Simon, 1873. A key to all genera and major lineages is provided along with corresponding diagnoses, as well as descriptions of selected species. These are documented with collections of photographs, scanning electron micrographs, and illustrations. A new phylogeny of Eresidae based on molecular sequence data expands on a previously published analysis. A species of the genus Paradonea Lawrence, 1968 is sequenced and placed phylogenetically for the first time. New sequences from twenty Gandanameno Lehtinen, 1967 specimens were added to investigate species limits within the genus. The genus Loureedia gen. n. is proposed to accommodate Eresus annulipes Lucas, 1857. Two species, Eresus semicanus Simon, 1908 and Eresus jerbae El-Hennawy, 2005, are synonymized with Loureedia annulipes comb. n. One new species, Paradonea presleyi sp. n. is described. Eresus algericus El-Hennawy, 2004 is transferred to Adonea Simon, 1873. The female of Dorceus fastuosus C. L. Koch, 1846 is described for the first time. The first figures depicting Paradonea splendens (Lawrence, 1936) are presented.

本研究对Eresidae科（C. L. Koch, 1850）开展了属级分类学修订。该科共计9个属，其中包含1个新属，分别为：Adonea Simon, 1873、Dorceus C. L. Koch, 1846、Dresserus Simon, 1876、Eresus Walckenaer, 1805、Gandanameno Lehtinen, 1967、Loureedia gen. n.（新属）、Paradonea Lawrence, 1968、Seothyra Purcell, 1903以及Stegodyphus Simon, 1873。本研究提供了该科所有属及主要支系的分属检索表与对应鉴别特征，并对部分物种进行了形态描述；上述研究内容均辅以照片集、扫描电子显微镜（scanning electron micrograph）图像及手绘图版进行佐证。本研究基于分子序列数据构建了Eresidae科全新的系统发育树，对既往已发表的系统发育分析进行了拓展完善。本研究首次对Paradonea Lawrence, 1968属的1个物种完成了分子测序并进行了系统发育定位。本研究新增了20号Gandanameno Lehtinen, 1967属标本的分子序列数据，用以探究该属的物种界定问题。本研究提议建立新属Loureedia gen. n.，以收纳原隶属于Eresus的Eresus annulipes Lucas, 1857；将Eresus semicanus Simon, 1908与Eresus jerbae El-Hennawy, 2005这2个物种处理为Loureedia annulipes comb. n.（新组合）的异名。本研究描述了1个新种：Paradonea presleyi sp. n.。本研究将Eresus algericus El-Hennawy, 2004移至Adonea Simon, 1873属之下。本研究首次对Dorceus fastuosus C. L. Koch, 1846的雌性个体进行了形态描述。本研究首次提供了Paradonea splendens (Lawrence, 1936)的形态图解。
