Oniticellini
Oniticellini are a tribe of scarab beetles, in the true dung beetle subfamily (Scarabaeinae The scarab beetle subfamily Scarabaeinae consists of species collectively called true dung beetles (there are also dung beetles in other subfamilies and families). Most of the beetles of this subfamily feed exclusively on dung. However, some ma ...). Nearly all species of this tribe feed on and nest in dung, mainly that of large herbivores. Most are tunnelers; dung is buried at the ends of tunnels dug below a dropping, and used as food by both adults and larvae; others, known as dwellers (including '' Oniticellus'' and '' Tragiscus'') make brood cavities within or just beneath the dung. Taxonomy The Oniticellini have been divided into three subtribes: Drepanocerina, Helictopleurina and Oniticellina, but this arrangement is still under review. The following genera have been placed in the Oniticellini: *'' Afrodrepanus'' *'' Anoplodrepanus'' *'' Attavicinus'' *'' Clypeodrepanus'' *'' ...

Eurysternus
''Eurysternus'' is a genus of Scarabaeinae or dung beetles in the family Scarabaeidae. It is normally placed in the Oniticellini, although some authors consider it the single genus in the tribe Eurysternini (e.g.). It is restricted to the Neotropics and includes 53 recognized species. They have a characteristic nesting strategy among dung beetles, with brood ball elaboration but no ball rolling behaviour. The species in the genus are present from Mexico to Argentina, but highest diversity is found the Amazon River, Amazon basin, the Andes and Central America. Species distribution is affected primarily by annual mean temperature and annual precipitation. The species with wide climatic niches would primarily inhabit the rainiest and coldest locations in the continent. References Scarabaeinae {{Scarabaeinae-stub ...
