Resumen

In Peru, 62 species of Elmidae have been recorded, classified in 22 genera, including Gyrelmis, previously represented in the country by three species. In the present study, material deposited in the Aquatic Invertebrates Laboratory of the Biological Science Faculty of Universidad Nacional Mayor de San Marcos and in the Entomological Collection of the Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos (MUSM) was examined, comprising 70 specimens of Gyrelmis from the department of Madre de Dios. Six species of Gyrelmis were determined, the three previously recorded for Peru: G. brunnea, G. longipes, and G. maculata, and three additional species: G. glabra, G. pusio, and G. rufomarginata, which represent new country records. With these findings, the number of Elmidae species known from Peru increases to 65. In this work, we also provide updated distributional data and locality records for the treated species, along with illustrative photographs. © Los autores.
