Abstract

The third-instar larvae of Megasoma sleeperi Hardy are illustrated and described based upon three larval specimens. The larvae were hatched in captivity from eggs obtained from adult females collected near Glamis, Imperial Co., California, USA, in mid-September 2003. Their structure is compared with that of Megasoma occidentalis Bolivar y Pieltain et al. and Megasoma cedrosa Hardy in order to find species-level characters. A description of the adult male is included, based upon the examination of three males.
