''Proceratium'' is a rare genus of ants in the subfamily Proceratiinae. It is the type genus of the tribe (biology), tribe Proceratiini, which in addition to ''Proceratium'' consists of two even rarer genera: the extant ''Discothyrea'' and the fossil genus ''Bradoponera''.

Distribution

The genus is rare, but widespread throughout the northern Temperate climate, temperate and tropical zones. In the Old World, it is distributed from Spain to Japan, in sub-Saharan Africa, Mauritius, the Malay Archipelago, New Guinea, Queensland (Australia) and Fiji. In the New World, it is known from Canada to Brazil (and some Caribbean islands).

Biology

file:Proceratium eocenicum paratype GPIH-BE4507 Profile whole.jpg, ''Proceratium eocenicum, P. eocenicum'' male Colonies are relatively small, usually containing less than 200 individuals. They nest in soil, in rotten wood, under stones, or on tree branches. Similar to its sister genus ''Discothyrea'', some species are specialist predators of arthropod eggs, mainly spider eggs.
