The only non-type collection of this species was found in a forest litter-sample.
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.

Description
Worker
HOLOTYPE. TL 2.3, HL 0.63, HW 0.43, CI 68, ML 0.24, MI 38, SL 0.24, SI 56, PW 0.31, AL 0.60. Characters of crassicornis complex. Apicodorsal tooth of mandible in full-face view distinctly hooked posteriorly. Proximal of apicodorsal tooth with 4 - 5 minute denticles and a much larger submedian tooth that is weakly sloped posteriorly. Proximal to submedian tooth is a row of 3 - 4 minute denticles that terminates at about the basal quarter. Apex of mandible with 4 intercalary denticles between apicodorsal and apicoventral teeth. Outer margin of mandible not obviously concave through its median third. Head markedly flattened, in profile the maximum vertical distance between highest and lowest points of head capsule is 0.35 - 0.40 X HL.
PARATYPE. TL 2.2, HL 0.61-0.62, HW 0.41-0.42, CI 66-69, ML 0.23-0.24, MI 37-39, SL 0.24, SI 57-58, PW 0.28-0.30, AL 0.58-0.60 (2 measured).
