Brachymyrmex minutus is a small, inconspicuous, soft bodied yellow species native to the Neotropics. It occurs in the Caribbean, including some of the smallest Bahamian cays (Morrison, 2006), and is also introduced in Florida. In his original description Forel (1893)compares it to B. heeri, noting the B. minutus has longer scapes than B. heeri, and is generally more slender, small and pale. Forel also discussed the biology of the species, writing that it was rather rare, lived in colonies of up to 150 individuals, excavated nests with wide tunnels and small chambers amongst the roots of sod. Brachymyrmex minutus is introduced in Florida, where it nests in the leaf litter (Deyrup et al., 2000). It was first reported there in 1994 (Ferster & Prusak, 1994), but specimens have been identified from 1984 (Deyrup et al., 2000). Very little else is known about the biology of the species.
