Ocymyrmex robustior

Chance observation by Marsh in the Namib Desert indicates that mating almost definitely occurs at night, probably at almost any time of the year, and takes place at the nest entrance of the mother colony. Their main food supply is obtained by scavenging dead or heat-stressed insects. (Bolton and Marsh 1989).

Identification
A member of the  barbiger group.

Key to Ocymyrmex workers

Distribution based on Regional Taxon Lists
Afrotropical Region: Namibia.

Biology
A series of papers focused on Ocymyrmex biology (Marsh, 1985 a, 1985 b), or on Ocymyrmex species as a component of the Namib Desert ant community (Marsh, 1985 c, 1986 a, 1986 b) included information about robustior. In all but the last of these papers the ant referred to as Ocymyrmex barbiger is actually Ocymyrmex robustior. At the times of publication of Marsh's first four papers robustior was incorrectly being treated as a junior synonym of barbiger. The former is now considered to be a valid species, separate from barbiger but belonging to the same species-group. The name robustior was elevated to species-level in Marsh (1986 b).
