Seven specimens of Sybra alternans (Wiedemann) (Cerambycidae: Lamiinae: Apomecynini) were captured with a UV light trap and by beating branches of trees in the urban area of Easter Island (Chile) during 2011–2016, representing the fi rst record of the species in this Chilean insular territory, but not continental Chile.
Sybra alternans is native to Southeast Asia and has been introduced accidentally to Hawaii and Florida in the United States of America. Data are presented from the literature on this species’ distribution, host plants, and biological information.
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.
