| |
The one specimen of this species was from a wet forest habitat, from a Winkler sample of sifted leaf litter from the forest floor (Longino, Ants of Costa Rica). A subsequent collection was made from a litter sample in montane moist forest (Panama).
Identification
Bolton (2000) - A member of the Strumigenys alberti-group.
Longino (Ants of Costa Rica) - Mandibles in side view straight, not broadly curved ventrally; mandibles relatively short, subtriangular, much of the apical portion meeting along a serially toothed masticatory margin when closed (former Smithistruma); leading edge of scape with a row of conspicuous projecting curved hairs, of which those distal to the subbasal bend distinctly curve toward the base of the scape; pronotal humeral hair present; ventral surface of petiole in profile with a deep, conspicuous and very obviously spongiform curtain, its maximum depth at least half that of the peduncle and usually more; disc of postpetiole completely unsculptured and glassy smooth; anterior border of clypeus broadly rounded; basal lamella of mandible immediately followed distally by the tooth-row, without a second lamella that extends forward for half the exposed length of the fully closed mandible; mandibles short, MI 19-24; compound eye composed of about 4 facets (approximately 10 facets in nigrescens and fridericimuelleri); promesonotal dorsum without a median longitudinal carina; pronotal dorsum entirely smooth and shining; propodeal dorsum smooth and shining. Similar to Strumigenys fridericimuelleri and Strumigenys nigrescens.

Description
Worker
HOLOTYPE. TL 1.9, HL 0.52, HW 0.36, CI 69, ML 0.12, MI 23, SL 0.26, SI 72, PW 0.24, AL 0.50. Basal lamella mostly visible in full-face view with mandibles fully closed, the lamella followed immediately by a row of 5 acute triangular teeth; no secondary lamella and no alternation of tall pointed and low rounded teeth. Anterior clypeal margin prominently arched-convex between points where outer margins of closed mandibles intersect anterior clypeal margin. Apicoscrobal hair flagellate, long and fine. Eye very small, with only 2 ommatidia in the longest row and only 4 ommatidia in total. Promesonotal dorsum without a median longitudinal carina, the dorsum and sides of the pronotum unsculptured, smooth and shining. Mesonotum and propodeal declivity reticulate-punctate but dorsum of propodeum smooth. Petiole node in dorsal view smooth, slightly broader than long and with thick, strongly prominent lateral spongiform lobes.
