ABSTRACT
The yucca moths (Tegeticula and Parategeticula; Lepidoptera, Prodoxidae) are well known for their obligate relationship as exclusive pollinators of yuccas. Revisionary work in recent years has revealed far higher species diversity than historically recognized, increasing the number of described species from four to 20. Based on field surveys in Mexico and examination of collections, we describe five additional species: T. californica Pellmyr sp. nov., T. tehuacana Pellmyr & Balcázar-Lara sp. nov., T. tambasi Pellmyr & Balcázar-Lara sp. nov., T. baja Pellmyr & Balcázar-Lara sp. nov. and P. ecdysiastica Pellmyr & Balcázar-Lara sp. nov. Tegeticula treculeanella Pellmyr is identified as a junior synonym of T. mexicana Bastida. A diagnostic key to the adults of all species of the T. yuccasella complex is provided. A phylogeny based on a 2104-bp segment of mitochondrial DNA (mtDNA) in the cytochrome oxidase I and II region supported monophyly of the two pollinator genera, and strongly supported monophyly of the 17 recognized species of the T. yuccasella complex. Most relationships are well supported, but some relationships within a recent and rapidly diversified group of 11 taxa are less robust, and in one case conflicts with a whole-genome data set (amplified fragment length polymorphism, AFLP). The current mtDNA-based analyses, together with previously published AFLP data, provide a robust phylogenetic foundation for future studies of life-history evolution and host interactions in one of the classical models of coevolution and obligate mutualism.

絲蘭蛾以其與寄主植物絲蘭的專一性傳粉形成之互利共生關係而聞名，近年來的訂正研究將其種類由4種增加至20種，本文描述5新種絲蘭蛾，並以粒線體DNA的CO與COII片段重建Tegeticula與Parategeticula兩屬絲蘭蛾的親緣關係，再與由AFLP得到的全基因體資料所重建之親緣關係進行比較，此結果未來可供探討生活史演化或專一性互利共生之共演化模型。
