Diagnosis. Mandible striate; anterior clypeal margin truncate; side of head with evenly distributed short erect setae; face sculpture of dense, minute puncta overlain with larger, more widely spaced puncta visible in particular orientation and lighting; petiolar node subcuboidal. Three species are within geographic and size range of R. subcubitalis:

Rasopone ferruginea (Fig. 11; Supp Figs. S12 and S 13 [online only]): anterior clypeal margin sinuous; petiole more scale-like.

Rasopone guatemalensis (Fig. 8; Supp Figs. S14 and S15 [online only]): mandible smooth; petiole more scale-like.

Rasopone politognatha (Fig. 9; Supp Figs. S28 and S29 [online only]): mandible smooth and shining.

Measurements, worker: HW 1.25 (1.21–1.30, 9); HL 1.40 (1.36– 1.44, 9); SL 1.06 (1.03–1.09, 3); PTH 0.94 (0.90–1.00, 8); PTL 0.52 (0.50–0.55, 8); CI 89 (88–90, 9); SI 84 (84–85, 3); PTI 55 (53–60, 8).
