Megatibicen cultriformis
Grand Western Flood Plain Cicada
Megatibicen cultriformis is a large cicada species in the family Cicadidae, commonly known as the Grand Western Flood Plain Cicada. It is distributed across the southwestern United States and northern Mexico, with confirmed records from Arizona, New Mexico, and Sonora. The species was described by Davis in 1915 and is currently classified in the genus Megatibicen, which was separated from the broader Tibicen group based on morphological and molecular evidence. As a member of the tribe Tacuini, it shares characteristics with other large-bodied North American cicadas.
