First record of Athetis rionegrensis (Lepidoptera: Noctuidae) attacking soybean and new geographical report in Argentina

The genus Athetis Hübner (Lepidoptera. Noctuidae. Amphipyrinae) comprises numerous species worldwide, two of them recently reported as pests of maize in China. This work presents the first record of an Athetis species feeding on soybean in the eastern region of the province of Córdoba, Argentina. The specimens were identified as Athetis rionegrensis status rev. based on external morphology and genitalia characters for both sexes. Furthermore, additional specimens were collected in the province of La Pampa, Argentina, on October, 2021.This species was only known to be in Alto Valle, province of Río Negro, Argentina, therefore these specimens represent the first record of the species outside that province. The correct assignment of this species to the Athetis genus is confirmed. Finally, the implications of this new record are discussed.
