Ants in the Pseudomyrmex gracilis HNS species complex are ubiquitous in the neotropics, and the species P. gracilis HNS itself presents a confusing array of variation (Ward 1989). Santschi distinguished his variety P. atrinodus HNS on the basis of small size and light coloration on parts of the mesosoma, but I have examined the type material and in both these characters P. atrinodus HNS is well within the normal range of variation of the species. Phil Ward, who is revising Pseudomyrmex HNS , concurs with this synonymy (Ward, pers comm.)

Diagnosis of worker among Antkey species. Head ovoid. Antenna 10-segmented. Antennal club indistinct. Antennal scrobe lacking. Antennal insertion not surrounded by a raised sharp-edged ridge. Antennal scapes do not extend beyond posterior margin of head. Eyes extremely large (approximately half head length); 3 ocelli present. Mandibles triangular. Propodeum lacking spines or teeth. Either bicolored red and black or uniformly black.
Although Pseudomyrmex gracilis has a 2-segmented waist like myrmicines, it is immediately recognizable Among Antkey species by the combination of its enormous eyes and short antennal scapes. It has a wasp-like behavior, frenetically moving its antennae.

Worker:
- masticatory margin of mandible with 7-10 teeth
- median clypeal lobe laterally rounded
- eyes large and elongate (REL2 0.54-0.60)
- pronotum dorsolaterally submarginate
- petiole long and slender (PLI 0.46-0.57) with a well developed anterior peduncle
- head and mesosoma densely and finely punctulate-coriarious to coriarious-imbricate, subopaque to sublucid (not matte) in appearance
- standing pilosity abundant, fine, predominantly pale silvery-white (not black), common on mesosoma dorsum and on external faces of tibiae
- size and color extremely variable (HW 1.39-2.07), varying from unicolorous black (appendages lighter) to unicolorous orange-brown, with many intermediate and bicoloured combinations
