Biology
Sharaf et al. (2016) discuss this species introduced to Saudi Arabia: This species was found nesting in soil at the base of a date palm tree (Phoenix dactylifera L.) in King Saud University campus, Riyadh. Specimens were collected by sifting the soil which was a mixture of sandy clay, with much decaying organic material. Workers were found about 8 cm deep in the soil. Other ant species collected with B. cordemoyi included: Solenopsis saudiensis, Nylanderia jaegerskioeldi Tapinoma simrothi and Cardiocondyla mauritanica.

Taxonomic Notes
Deyrup, Davis & Cover (2000) report a single collection of this species (as B. brevicornis) from Columbia County, Florida, in a mesic forested area. However, the identity of this species is problematical and the occurrence of this taxon in Florida needs to be confirmed.
