Resumen
La Patagonia argentina es una amplia región que alberga diversos ambientes, con un conocimiento limitado acerca de su artropodofauna. Las mantis son insectos predadores que pueden actuar como enemigos naturales de plagas y desempeñan un importante rol ecológico. En esta nota se reporta por primera vez a las especies Coptopteryx argentina Burmeister y Brunneria subaptera Saussure (Mantodea: Coptopterygidae) para la provincia del Chubut. Ambas fueron observadas en el Valle Inferior del Río Chubut (VIRCh), un agroecosistema irrigado emplazado en un ambiente árido. Los datos aquí aportados expanden ampliamente la distribución conocida para ambas especies (entre 500 y 800 km hacia el sur), siendo estos ahora los registros más australes. Por otro lado, adicionan dos especies nuevas para la provincia del Chubut, ampliando notablemente la información existente sobre las mantis presentes en este territorio. Esta nota contribuye al conocimiento local de la entomofauna benéfica del VIRCh y aporta a otras disciplinas, como al estudio del control biológico conservativo a nivel regional.
Argentine Patagonia is a vast region that harbors diverse environments, with limited knowledge about its arthropod fauna. Mantids are predatory insects that can serve as natural enemies of pests and play an important ecological role. In this note we report for the first time the species Coptopteryx argentina Burmeister and Brunneria subaptera Saussure (Mantodea: Coptopterygidae) for the Chubut Province. Both were observed in the Lower Chubut River Valley (VIRCh), an irrigated agroecosystem located in an arid environment. The data provided here greatly expand the known distribution of both species (between 500 and 800 km to the south), which are now the southernmost records. On the other hand, they add two new species to the Chubut Province, significantly expanding the existing information on mantids present in this territory. This note contributes to the local knowledge of the beneficial entomofauna of the VIRCh and contributes to other disciplines, such as the study of conservative biological control at the regional level.
