Brazil (São Paulo).


This species has the posterior face of the propodeum with large foliaceous crests instead of acute propodeal spines, a trait shared with E. pilulifera from Central America. It differs in the much larger body size and the tooth-like development of the posterior face of the petiolar node. The head shape and pilosity patterns are much like E. gravis. Measurements for workers of this species, as reported in Kempf (1967) are HW 0.91–0.99, HL 0.86–0.93, CI 100–106, SLI 9–12 (n=7). Measurements for the queen are HW 1.17, HL 1.12, CI 105. This is the largest New World species so far reported, with E. gravis being second largest. Queen HW is 1.22 x worker HW, the largest difference of any New World species. Most species for which queens and workers are known fall on a single line of allometry, with queen HW 1–1.1 x worker HW. The two largest species, E. gravis and E. lenkoi, deviate from the line with ratios 1.12 and 1.21, respectively.
