Redescription of immature stages and adults of Nilio (Nilio ) brunneus (Coleoptera: Tenebrionidae: Nilioninae)

ABSTRACT We described immature stages of Nilio (Nilio ) brunneus Thomson, 1860 and provide a supplementary description for adults, including new data on the anatomy of the female and male terminalia. We observed N. brunneus feeding on the lichen Parmotrema sp., and that immature and adult are gregarious, with sessile pupae and generations overlapping. In laboratory, eggs hatched in 14 days and adults emerged after seven days in the pupal stage, the adults survived only a few days.
