Abstract
The yucca moths (Parategeticula Davis and Tegeticula Zeller; Lepidoptera: Prodoxidae) are known for their obligate mutualism with yuccas (Yucca: Agavaceae). Three new species of the previously monobasic Parategeticula are described from Mexico, and the genus is redescribed. The new species P. elephantipella, P. martella, and P. tzoyatlella share highly modified nonpiercing ovipositors with P. pollenifera Davis, a synapomorphy within all Incurvarioidea. Phylogenetic relationships are discussed, with morphological apomorphies mapped. Evidence for early evolution of the distinctive life habits of Parategeticula suggest that the interactions between these moths and their hosts can provide insights into the origin and early diversification of the obligate mutualism.RESUMENLas “palomillas de la yuca” (Parategeticula Davis y Tegeticula Zeller; Lepidoptera: Prodoxidae) son bien conocidas debido a su mutualismo obligado con las yucas (Yucca: Agavaceae). En este trabajo se redescribe el género Parategeticula, previamente considerado monobásico, y se describen tres nuevas especies de México. Las nuevas especies P. elephantipella, P. martella, y P. tzoyatlella comparten la presencia de un ovipositor no cortante, altamente modificado con P. pollenifera Davis, una sinapomorfía dentro de Incurvarioidea. Se discuten sus relaciones filogenéticas y se muestran gráficamente las apomorfías morfológicas sobre un cladograma. Evidencia de la evolución temprana de los distintivos hábitos de Parategeticula sugieren que las interacciones entre estas palomillas y sus hospederos pueden permitir comprender el origen y la diversificación temprana del mutualismo obligado.
