Odontomachus brunneus

Identification
Deyrup and Trager (1985) - Worker: gaster densely covered with fine, almost contiguous appressed hairs; striations of pronotum not transverse posteriorly; petiolar node faintly rugose at extreme base only; inner side of hind femur at base finely pubescent; color piceous in n. Florida, body (except gaster) frequently lighter in s. Florida. Male: each ocellus as wide as the ocello-ocular space, ocelli on a conspicuous turret: petiole smooth; head and body entirely yellowish orange.

Distribution
Occurs in xeric areas in Mexico, southwestern US, Florida (Deyrup and Trager 1985). It also has a wide range in the remainder of the neotropics but the limits of its distribution are presently unclear.

This taxon was described from U.S.A.

Biology
In Florida Deyrup and Trager (1985) found that brunneus occurred in wet areas such as hammocks and ditches. Males were found to fly in the spring.
