Identification
Worker: Head with convex sides and posterior margin with a wide but relatively shallow concavity mesad. In profile, wide mesopropodeal depression formed by the posterior face of the mesonotum and the anterior propodeal face. Propodeal declivity twice as long as its dorsal face. Dorsum of pronotum with two erect setae, longer and thinner than those found in Forelius heyeri. Concolorous brown ants. (Guerrero, 2021)
Queen: Head rectangular, twice as long as wide (CI ≤ 46). Relatively long antennal scapes, SL > 0.70 mm. Large ants with shorter mesosomas (WL ≤ 1.65 mm) than Forelius pruinosus (WL 1.74) and Forelius mccooki (WL 1.67).
