Nests and brood balls of two South American species of Sulcophanaeus olsoufieff, 1924 (Coleoptera: Scarabaeidae: Scarabaeinae: Phanaeini)

Nests of Sulcophanaeus menelas (Laporte) and Sulcophanaeus imperator (Chevrolat) are composed of single or branched, vertical to horizontal tunnels, empty or partially filled with dung, and at most one nesting chamber bearing a brood ball. Horizontal, branched nests were found made only by S. impera...
