本文对北美地区的劳亚族鲶科种类进行了系统发育学研究，并与欧洲和日本的种类进行了比较。北美的进化枝没有被解析为单系。系统发育分析和详细的形态学研究确定了美国西部的四种神秘的sironids，以前被认为是在地理和形态范围内的siroacaroides（Ewing，1923）。这4个种被描述为Siro boysp. nov.，Siro calaveras sp. nov.，n.克劳氏细角叶蝉，和Siro shasta sp. nov.我们还提供了新的地点，以前已知的种在美国西部。与Siro kamiakensis（纽韦尔，1943）和东海岸种Siro exilis霍夫曼，1963形成一个分支，其特征是存在不沿中线沿着相遇的狭窄基节III。S. Calaveras sp. nov.，S. Clousi sp. nov.，和S. shastasp. nov.，但S. Clousi sp. nov.，与S无关。尽管在同域发现，但仍有螨类。
Abstract The North American fauna of the Laurasian family Sironidae is examined phylogenetically and compared with species from Europe and Japan. The North American clade is not resolved as monophyletic. The phylogenetic analyses and detailed morphological study identified four cryptic species of sironids in the western United States, formerly considered within the geographical and morphological range of Siro acaroides (Ewing, 1923). These four species are described as Siro boyerae sp. nov., Siro calaveras sp. nov., Siro clousi sp. nov., and Siro shasta sp. nov. We also provide new localities for the previously known species in the western United States. Siro boyerae sp. nov. forms a clade with Siro kamiakensis (Newell, 1943) and with the East Coast species Siro exilis Hoffman, 1963, characterized by the presence of narrow coxae III that do not meet along the midline. The affinities of S. calaveras sp. nov., S. clousi sp. nov., and S. shasta sp. nov. remain largely unresolved, but S. clousi sp. nov., is not related to S. acaroides despite being found sympatrically.
