The presence of Ancognatha erythrodera (Blanchard, 1846) (Coleoptera: Scarabaeidae) is confirmed for the first time in Chile based on male and female specimens collected in the extreme north of the country. This is the second species of Ancognatha Erichson, 1847 recorded in Chile. Morphological characters, illustrations of male genitalia, male and female habitus photographs of this species, and additional records in Argentina and Bolivia are provided. A map with the collection sites and montane habitats photograph in Chile are included.

The Dynastinae (Coleoptera: Scarabaeidae) that occur in Chile were comprehensively revised by Ratcliffe et al. (2021), who recorded nine species in six genera. One of these genera, Ancognatha Erichson, 1847, includes 23 valid species found from the southwestern United States (Arizona and New Mexico) to northern Argentina, Chile, and Bolivia (Mondaca 2016; Moore et al. 2018a; Paucar-Cabrera and Ratcliffe 2018; Ratcliffe et al. 2021). In this note, we report the first record of Ancognatha erythrodera (Blanchard, 1846) in Chile, based on specimens collected in the altiplanic locality of Visviri, Región de Arica y Parinacota. Previously, Ancognatha erythrodera was recorded for the Andes of southern Peru, Bolivia, and northwestern Argentina (Moore et al. 2018b). This new record corresponds to the natural distribution of this species on both sides of the Andes mountain range, which is not surprising due to the similarity of habitats in neighboring localities in Peru, Bolivia, and Argentina.
