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.

隆头蛛科（Eresidae）是1850年由C. L. Koch建立的蜘蛛类群，本研究对其属级分类进行了系统综述。该科共计包含9个属，其中1个为新属，分别为：Adonea Simon, 1873、Dorceus C. L. Koch, 1846、Dresserus Simon, 1876、Eresus Walckenaer, 1805、Gandanameno Lehtinen, 1967、Loureedia 新属（gen. n.）、Paradonea Lawrence, 1968、Seothyra Purcell, 1903以及Stegodyphus Simon, 1873。

本文为该科所有属及主要演化支提供了分类检索表与对应的鉴别特征，并对部分代表性物种进行了形态描述，所有类群均辅以实物照片、扫描电子显微照片及手绘线条图予以佐证。

本研究基于分子序列数据构建了隆头蛛科全新的系统发育框架，拓展了此前已发表的相关分析。研究首次对Paradonea Lawrence, 1968属的1个物种进行了分子测序并完成系统发育定位；同时新增了20号Gandanameno Lehtinen, 1967属标本的分子序列，以厘清该属内的物种界定边界。

本研究建立新属Loureedia gen. n.，以收纳原隶属于Eresus Walckenaer, 1805的Eresus annulipes Lucas, 1857；将Eresus semicanus Simon, 1908与Eresus jerbae El-Hennawy, 2005定为Loureedia annulipes comb. n.的同物异名；描述了1个新种Paradonea presleyi sp. n.；将Eresus algericus El-Hennawy, 2004转移至Adonea Simon, 1873属；首次对Dorceus fastuosus C. L. Koch, 1846的雌性个体进行了形态描述；并首次提供了Paradonea splendens (Lawrence, 1936)的形态插图。
