Brachymyrmex santschii

Identification
Ortiz-Sepulveda et al. (2019) - Brachymyrmex santschii morphologically resembles Brachymyrmex iridescens, because both species have the head and the mesosoma with strongly alveolate sculpture. However, they can be distinguished from one another because B. santschii has a metanotal groove that is wider than the diameter of the metathoracic spiracles, scapes that surpass the posterior margin of the head, and a gaster with scattered pubescence.
