A new species of the rare long-horned caddisfly genus Holzenthal is described from Ecuador, bringing the number of species known from the genus to 15. All species are very regional in their distributions and known only from very few specimens. The new species, , is similar to a number of previously described species from Colombia (, , , , and ) and Ecuador ( and ). The males can be distinguished from the others by features of segment X of the male genitalia, especially the prominent midlateral and subapicodorsal spinelike setae. An updated taxonomic key to males of the genus is provided.
一种罕见的长角石蛾属新物种在厄瓜多尔被发现并描述，这使得该属已知物种数量增至15种。所有物种分布范围都非常有限，仅从极少标本中被知晓。新物种 与先前在哥伦比亚（ 、 、 、 、 ）和厄瓜多尔（ 和 ）描述的一些物种相似。雄性可通过雄性生殖器第十节的特征与其他物种区分开来，特别是突出的中侧和近顶端背侧的刺状刚毛。文中还提供了该属雄性的最新分类检索表。
