subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoologi ...
( Scarabaeinae). Scholtz et al. describe them as tunnellers that are shiny black, of moderate to large size (9–30 mm long) and with a strongly convex shape. They also, however state that the grouping based on these characteristics has little phylogenetic validity, and the placement of several genera in this and related tribes is likely to change.

Most species are nocturnal. They are predominantly coprophagous, but some are necrophagous. Dung is rapidly buried in shallow tunnels and then used for nest construction in deeper tunnels.
