Desarrollo larval de Canthon cyanellus cyanellus LeConte 1859 (Coleoptera: Scarabaeidae)

The larval development of Canthon cyanellus cyanellus LeConte was analyzed upon 92 larvae of known age. Larval stage lasted nine days and consists of three instars; each one with a particular length of time and specific cephalic-width range. Most of the anatomical larval features appear since the first instar and they strengthen in the following two. The comparison of several anatomical features among larvae of Canthon cyanellus cyanellus, C. pilularius Linnaeus, C. humectus humectus Say and C. edentulus Harold showed that C. cyanellus cyanellus and C. pilularius, shared the most numerous characters in common wich could indicate that these species are taxonomically close.
