Abstract
Trichillum hirsutum Boucomont (Coleoptera: Scarabeidae: Scarabaeinae) is redescribed because of errors in the original description. New distribution records are presented for Trichillum hirsutum Boucomont, Ipselissus alvarengai Pereira and Martinez (new state records); and Trichillum boucomonti Saylor and Cryptccanthon peckorum Howden (new country records for Brazil).
