Strumigenys bryanti

Identification
Bolton (2000) - A member of the doriae complex in the Strumigenys doriae-group. Closest related to Strumigenys hekate (see under Strumigenys doriae), from which it separates as follows.

S. bryanti: Mandible without trace of preapical dentition. Humeri of pronotum evenly broadly rounded in dorsal view. Mesonotum in profile forming a long convex arc that slopes steeply down to the propodeum, the latter on a much lower level. First gastral tergite without dense short grey pubescence between the main pilosity.

S. hekate: Mandible with two minute preapical denticles. Humeri of pronotum distinctly angulate in dorsal view. Mesonotum in profile forming a short, flat, shallowly sloping surface, the propodeum only on a slightly lower level. First gastral tergite with a dense coat of short grey pubescence between the main pilosity.

Worker
Bolton (2000) - TL 4.2, HL 1.10, H W 0.71, CI 65, ML 0.58, MI 53, SL 0.70, SI 99, PW 0.42, AL 1.16. Mandible without trace of preapical dentition. In anterior view apical fork of mandible forming a V-shape or very narrow-based U-shape, the dorsal fork tooth conspicuously longer than the ventral. Propodeal teeth invisible in profile or visible as a vague outline, either fully embedded in, or replaced by, spongiform tissue. Lateral spongiform lobe of petiole a short thick collar, restricted to posterior margin of node, not extending forward to the level of the spiracle on the peduncle. Dorsolateral margin of head with 5 or more long fine hairs and a number of shorter simple hairs that freely project laterally; apicoscrobal hair usually slightly longer than any of the other main projecting hairs, its length about 0. 60 X SL. With head in profile erect hairs that arise from the dorsum in front of the highest point of the vertex are much shorter than the longest hairs that arise between the highest point and the occipital margin; the longest of the latter is shorter than the maximum depth of the head capsule. Longest hairs on first gastral tergite about equal to length of tergite from base of limbus to apex and somewhat greater than the maximum depth of the first gastral segment in profile.
