We predicted that males and females would not display differences between sexes in selection of resources and grouping patterns because the species is monomorphic. Determining whether male and female oryx segregate resources would be useful in assessing whether sexes should be managed separately (Clutton-Brock et al., 1982; Kie and Bowyer, 1999).

The Carebara genus group (except Mayriella, see below) can be defined by the following traits (based partially on Bolton 2003): clypeus constricted posteriorly, narrowly inserted between frontal lobes; antennae 9 to 11 (rarely 8) -segmented with antennal club 2 or 3- segmented; antennal sockets and inner margins of frontal lobes in close proximity; median portion of clypeus usually bicarinate; clypeus always with a pair of setae, commonly a second pair of setae ("paracarinal" in Eguchi & Bui 2007 terminology); clypeus usually without an isolated clypeal seta (sporadically present); major workers, when present, with long heads; polymorphic to monomorphic.
