Pterosthetops is one of a number of hydraenid genera endemic to the Cape of South Africa, whose minute moss beetle fauna is amongst the most diverse on earth. Here seven species are described as new: Pterosthetops baini sp. nov., Pterosthetops coriaceus sp. nov., Pterosthetops indwei sp. nov., Ptersothetops pulcherrimus sp. nov., Pterosthetops swartbergensis sp. nov., Pterosthetops tuberculatus sp. nov. and Pterosthetops uitkyki sp. nov., all from mountains in the Western Cape region. New collection records are also provided for all five previously described members of the genus, together with a revised key. Pterosthetops appear to be specialist inhabitants of seepages over rock faces (hygropetric/madicolous habitats), rarely being found outside such situations.
翼胸甲螨是南非开普敦特有的众多水缨甲螨属之一，其微小的苔藓甲虫动物群是地球上最多样化的动物群之一。本文描述了七个新物种：拜氏翼胸甲螨新种、革质翼胸甲螨新种、因德维翼胸甲螨新种、极美翼胸甲螨新种、斯瓦特贝格翼胸甲螨新种、瘤状翼胸甲螨新种和乌特基翼胸甲螨新种，均来自西开普地区的山区。还提供了该属此前已描述的所有五个成员的新采集记录以及一份修订后的检索表。翼胸甲螨似乎是岩面渗流处（喜湿岩生/岩栖生境）的特有栖息者，很少在这种环境之外被发现。
