Abstract

Tibicen pruinosus (Say)—a large, arboreal cicada typically found in the central United States—is reported for the first time from Colorado. This new state record represents a significant western extension of this cicada's known range. Also reported are new records from Kansas that link the Colorado population to the previously known distribution of T. pruinosus. These results suggest that T. pruinosus has expanded its range westward, likely facilitated by human-induced changes in vegetation on the Great Plains. They also indicate the effectiveness of acoustic surveys as a tool for studying cicada distributions. Finally, an updated key including all 7 species of Tibicen now known from Colorado is provided. Por primera vez se ha reportado en Colorado la cícada Tibicen pruinosus (Say), una especie arbórea y grande que comúnmente se encuentra en la parte central de los Estados Unidos. Este nuevo registro estatal representa una extensión hacia el occidente bastante significativa del rango que se conoce de esta cícada. También se reportan nuevos registros en Kansas que vinculan la población de Colorado con la distribución que se conocía previamente de la T. pruinosus. Estos resultados sugieren que T. pruinosus ha expandido su territorio hacia el oeste, posiblemente debido a que lo han facilitado los cambios provocados por el hombre en la vegetación de las Grandes Llanuras. También, demuestran la eficacia de los monitoreos acústicos como herramienta para estudiar la distribución de cicadas. Finalmente, se provee de una clave actualizada que incluye a las 7 especies de Tibicen que ahora se conocen en Colorado.
