Abstract

Definitive incorporation of Callidiellum rufipenne (Motschulsky, 1860) to the Argentinian fauna of Cerambycidae (Coleoptera).

Abstract

Callidiellum rufipenne is mentioned as established in Argentina. The first known host plant (Cupressus macrocarpa) in Argentina and South America is given. Based on old pupal chambers observed in the branches of Cupressus macrocarpa and location of the trees in a suburban area, it is possible to say that Callidiellum rufipenne is well established in the country, possibly before 2003. It rears on dead fallen branches, not affecting living trees, a difference from the United States, where the larvae develop in living branches. Adults emerge in July and mid-August during the day.
