The long-horned caddisfly Schmid, 1955 (Leptoceridae: Leptocerinae) is a small genus endemic to the Andean region, especially Chile. Four decades after the last taxonomic revision, a new species, Desidério, Santana & Hamada sp. nov., is described and illustrated based on adult males collected from Parque Natural Tricahue in the central subregion of the Chilean Andes. Specimens were examined through genital dissection using heated KOH, photographed with a digital camera mounted on microscopes, and described using the DELTA system. A distribution map was produced in QGIS based on GBIF data and literature records, and an updated identification key for males of the ten known species of is presented. . sp. nov. closely resembles . and . , sharing key features such as paired lateral processes on tergum X and tripartite inferior appendages. However, it can be distinguished by its unique combination of genital features, including unequal lengths of the three processes of the inferior appendage. This discovery emphasizes the underexplored diversity of the Southern Andes and contributes to refining the taxonomy and biogeography of the genus. It also provides a framework for future phylogenetic studies incorporating immature stages and molecular data.
长角石蛾属Schmid，1955年（长角石蛾科：长角石蛾亚科）是一个小型属，为安第斯地区所特有，尤其是智利。在上一次分类修订后的四十年，基于从智利安第斯山脉中部次区域的特里卡韦自然公园采集的成年雄性个体，描述并图示了一个新物种，Desidério, Santana & Hamada sp. nov.。通过使用加热的氢氧化钾进行生殖器解剖来检查标本，用安装在显微镜上的数码相机拍照，并使用DELTA系统进行描述。基于全球生物多样性信息设施（GBIF）数据和文献记录，在QGIS中制作了分布图，并给出了该属已知十个物种雄性的更新鉴别检索表。新物种与[其他两个物种名称未给出]和[其他两个物种名称未给出]非常相似，具有一些关键特征，如背板X上的成对侧突和三分的下附肢。然而，它可以通过其独特的生殖器特征组合来区分，包括下附肢三个突起的长度不等。这一发现强调了南安第斯地区未被充分探索的多样性，并有助于完善该属的分类学和生物地理学。它还为未来纳入未成熟阶段和分子数据的系统发育研究提供了框架。
