Introduction Taxonomic History (provided by Barry Bolton, 2013) Brachymyrmex heeri subsp. depilis Emery, 1893: 635 (w.q.) U.S.A. Nearctic. Wheeler & Wheeler, 1953: 139 (l.). Raised to species: Santschi, 1923: 663. Senior synonym of Brachymyrmex nanellus: Creighton, 1950: 359; of Brachymyrmex flavescens: Cole, 1953: 266. Identification Brachymyrmex depilis is distinguished from other species in the group in this region by its lack of erect hairs (only a few on the edges of the gastral tergites) and relatively large eye. An undescribed species known only from FL is similar in that it lacks erect hairs, but the eye is much smaller with only 3-4 facets in the greatest diameter of the eye. Other yellow species known from the U.S., including a new species that has been collected from southern AL and MS, differ in that they have semi-erect hairs present on the promesonotum. Other species of Brachymyrmex known from this region are dark brown. Biology and Economic Importance Distribution Literature Cited Creighton, W. S. 1950. The ants of North America.
