Abstract

RIZZUTO, Susana. Observations on the larval biology in the genus Calydon (Coleoptera: Cerambycidae) with new records in Patagonia, Argentina. Rev. Soc. Entomol. Argent. [online]. 2009, vol.68, n.3-4, pp.391-396. ISSN 0373-5680.

20 specimens of Calydon submetallicum were collected from "roble pellín" (Nothofagus obliqua), an introduced species in the forests of western Chubut Province (Argentina). Larval tunnels and pupal chambers of Calydon submetallicum (Blanchard) (Coleoptera: Cerambycidae) are described in detail following the method proposed by Di Iorio, and the pupal chamber is illustrated for the first time. A revision of the host plants and updated distribution range of the genus is presented.

Keywords : Coleoptera; Cerambycidae; Calydon; Larvae; Nothofagus; Argentina.
