Rhytidoponera mayri

Identification
Large ants that, like Rhytidoponera taurus, have workers that are easily distinguished from other Rhytidoponera workers in the SWBP by their occipital cornicles.

Distribution based on Regional Taxon Lists
Australasian Region: Australia.

Biology
An inhabitant of semi-arid areas.

Polygynous colonies with several gamergates (Peeters 1987). Studies of reproductive biology have been published under the name "sp. 12". Nest sites are long lasting, making it a good model to study changes in colony kin structure using molecular markers (several papers by Wee Tek Tai)
