Strumigenys stenotes

Identification
Bolton (2000) - A member of the crassicornis complex in the Strumigenys gundlachi group. At first glance stenotes appears as a larger, more stockily built version of Strumigenys zeteki, and indeed the two are very close. However, the size difference is very obvious, the outer margin of the mandible is not distinctly concave in stenotes and the mandible generally has fewer denticles. For general description of head, body and pilosity see under zeteki.
