Canthon (Pseudepilissus) Muticus Muticus harold, 1868 (Coleoptera: Scarabaeidae): Descriptions of the third instar and pupa

摘要

The third instar and pupa of Canthon muticus muticus Harold are described and illustrated. The larvae were reared from eggs laid by adults under laboratory conditions. Morphology of the two stages is analyzed based on characters at the generic level. Larval morphology is compared with that of other species of Canthon Hoffmansegg. Species can be distinguished by a combination of head chaetotaxy and stridulatory teeth. The pupae of Canthon vary only by the pronotal projections.
