On new or poorly known Australian Filistatidae spiders (Araneae: Araneomorphae), including a study on the fine morphology of <i>Wandella</i>

I present an update on the taxonomy of the filistatid genera <i>Wandella</i> Gray and <i>Yardiella</i> Gray, both endemic to Australia. Two new species are described: <i>Wandella grayi</i> sp. nov., known from Queensland, and <i>Wandella infernalis</i> sp. nov., known from a single cave in Western Australia. The male of <i>Wandella australiensis</i> (L. Koch) and the females of <i>Wandella stuartensis</i> Gray and <i>Wandella waldockae</i> Gray are described and illustrated for the first time. New records are given for these and other species of Australian filistatids, including the first epigeal records of <i>Yardiella humphreysi</i> Gray, a species so far known only from caves. Updated distribution maps are presented. Additionally, I present novel morphological data for <i>Wandella</i> using light and scanning electron microscopy. The cephalothorax, spinning organs, genitalia and appendages of some species are illustrated in detail. I report the presence of a putative claw extensor muscle in the male palpal cymbium, and describe interesting modifications in the clypeal region of adult males. The phylogenetic significance of these characters is briefly discussed.

本研究对均为澳大利亚特有属的管巢蛛科（Filistatidae）<i>Wandella</i> Gray属与<i>Yardiella</i> Gray属的分类学修订情况进行了汇报。本次研究共描述两个新种：产自昆士兰州的<i>Wandella grayi</i> sp. nov.，以及仅发现于西澳大利亚州一处洞穴中的<i>Wandella infernalis</i> sp. nov.。本研究首次对<i>Wandella australiensis</i> (L. Koch)的雄性个体，以及<i>Wandella stuartensis</i> Gray与<i>Wandella waldockae</i> Gray的雌性个体进行形态描述与绘图展示。本研究提供了上述类群及其他澳大利亚管巢蛛科物种的新分布记录，其中包括此前仅知分布于洞穴中的<i>Yardiella humphreysi</i> Gray的首次地表栖息记录。本研究附上了更新后的物种分布地图。此外，本研究借助光学显微镜与扫描电子显微镜，获取了<i>Wandella</i>属的全新形态学数据。本研究对部分物种的头胸部、纺器、生殖器及附肢进行了详细绘图。本研究报道了雄性触肢舟片内存在疑似爪伸肌的结构，并描述了成年雄性个体唇基区的独特特化修饰。本研究简要讨论了上述形态特征的系统发育意义。
