Description

Worker

Moffett (1986) - Major. HW 2.00, HL 1.99 (CI 100), SL 0.95 (SI 48), EL 0.21, HFL 1.08 (FLI 54; FWI 21) mm. Shallow oval foveae scattered, somewhat larger and denser near scrobes; traces of longitudinal rugae near scrobes. With a more clearly demarcated funicular scrobe than in any other Acanthomyrmex major examined. Cephalic hollow well-developed, with a conspicuous medial sulcus extending below it to the frontal area. Darkly pigmented medial streak on head long, extending into hollow. Clypeal index 178. Forward margin of clypeus with a medial projection. Condition of hypostomal teeth unknown.

Propodeal spines short, conspicuously curved caudad. Pronotal angle drawn out into a feeble tooth. Node of petiole as in figure, PWI intermediate (ca. 69). Anterior peduncle of petiole relatively short and deep, and with lateral hairs present, but sublateral pair lacking; subpetiolar declivity present. Postpetiole subrectangular, similar to that of Acanthomyrmex crassispinus. Dorsal surface of postpetiole and gaster hairy. Femora hairy, and with ventral surfaces distinctly concave. Color orange yellow.
