Worker
Holotype: ML 0.261, HL 0.506, HW 0.415, SL0.237, MeL 0.512.

With the characters of the Strumigenys gundlachi group, sensu Bolton (2000); inner margin of mandible evenly convex for nearly entire length; preapical mandibular dentition consisting of one small sharp tooth immediately proximal to apicodorsal tooth, followed by up to five minute denticles; eye with about 15 ommatidia; setae on leading edge of scape thicker apically but not broadly fan-shaped, first two setae (starting at base) strongly curving toward scape apex, next two strongly curving toward scape base, fifth curving toward scape apex; ground pilosity of clypeus, face, and promesonotum abundant, remiform, subdecumbent; dorsal face of propodeum and gastral dorsum lacking ground pilosity; katepisternum smooth and shiny, rest of mesosoma, head, petiole, and postpetiole punctate; metanotal groove not impressed, such that promesonotum and dorsal face of propodeum form single flat surface; gastral dorsum smooth and shiny with short, sparse basal costulae, plus variable extent of fine longitudinal striolation on basal fourth or less; pairs of stout clavate setae on sides of head at upper scrobe margin, upper face near vertex margin, pronotal humeri, mesonotum, and petiolar node; postpetiole and gaster with abundant stout clavate setae; color orange.

Queen
ML 0.273, HL 0.522, HW 0.436, SL0.253, MeL 0.603.

Similar to worker in mandibular structure, surface sculpture, pilosity, and color; katepisternum smooth and shiny as in worker, rest of side of mesosoma punctate; gastral dorsum longitudinally striolate in basal fourth.
