Abstract

We describe a new pest of guava (Psidium guajava L.), Hesperolyra guajavifoliae Stonis & Vargas, sp. nov., that was recently discovered in western Colombia. Hesperolyra van Nieukerken is a small, Neotropical genus of pygmy moths (Nepticulidae). We re-examine and document the complex morphology of the male genitalia of the generic type species, H. diskusi (Puplesis & Robinson). We discuss the diagnostics and composition of the genus and provide a simple pictorial differentiation scheme for all currently known representatives of the genus. The new species is illustrated with photographs of the adults, some of the immature stages, male and female genitalia, and leaf mines. A link to the COI barcodes of H. guajavifoliaesp. nov. is provided and the relationship of Hesperolyra to other genera is discussed.
