Pseudoneoponera

also known as The Foamy Ants. The genus is notable for the unusual foamy defensive secretions its workers exude from the sting, for its small colonies, and for its unusual social systems, including the frequent occurrence of gamergates.

Pseudoneoponera has received a fair bit of attention from researchers due to its unusual reproductive and social strategies. Just how widespread reproduction by gamergates is in Pseudoneoponera is unknown, but it may be characteristic of much or most of the genus. Interestingly, queens are unknown from all Australian Pseudoneoponera species, having only been found in some Indonesian species.

Workers of Pseudoneoponera are distinguished from other ponerines by their combination of robust build, coarse sculpturing.
