[2] With over 80 valid species, it is predicted that over half of the Meranoplus diversity remains undescribed, most of these from Australia.

[3] Meranoplus is a unique and charismatic myrmicine genus of hairy, slow-moving, and armored ants.

[3] The extant species of Meranoplus are distributed throughout the Old World, absent only from the Palearctic and Oceania regions but with the exception of M. levellei, from New Caledonia.

[3] Species of this genus are predominantly ground-nesting and, when disturbed, will display thanatosis enhanced by crypsis, i.e., individuals will accumulate dirt in their pilosity and play dead.

Meranoplus species are known to be active both day and night, and to recruit via pheromone trails laid from the base of the sting using secretions from their extremely large Dufour glands.
