Based on Ward et al., 2014

Hita Garcia, Wiesel and Fischer (2013) - Myrmicaria can be found throughout the Afrotropical, Oriental and Indo-Australian zoogeographical regions. In the Afrotropical region these ants seem to prefer open habitats where they can be locally quite abundant. They nest in the soil, and foraging is performed alone or in smaller groups (Levieux, 1983). Based on observations on one species (Levieux, 1983), members of the genus seem to be mostly carnivorous, with a diet consisting of a variety of insects, especially termites and ants and supplemented by homopteran honeydew.
