Comments

This species is known only from the type queen. Rasopone breviscapa , R. rupinicola , and R. titanis are the largest species in the genus, with HW ~1.7. Rasopone breviscapa has the anterior clypeal margin truncate, mandibles striate, and petiole intermediate between cuboidal and scale-like. It is differentiated from R. rupinicola ( Fig. 13 ; Supp Figs. S30 and S31 [online only]) by the shorter scapes (SI 79 vs 106), and from R. titanis ( Fig. 13 ; Supp Fig. S33 [online only]) by the truncate clypeal margin and striate mandibles.

Red boxes are type locality.

Fig. 2. Phylogeny of Rasopone, Mayaponera, and selected outgroup taxa,inferred using the program IQ-TREE and 1,802 UCE loci.Node support values (ultrafast bootstrap/SH-like) <100/100 are depicted with red dots. Terminal names show original, morphology-based species assignments and depict morphological convergence across clades. The ‘EX#’ code in terminal names indicate unique extraction codes that link specimens to specimen data in provided tables. Simopelta andersoni, a distant outgroup, is not shown in the figure. Images depict workers of Rasopone ferruginea (Nicaragua, CASENT0644264), Mayponera becculata (Peru, CASENT0374638, modified from AntWeb, credit Michele Esposito), and Mayaponera constricta (Bolivia, CASENT0249137, modified from AntWeb, credit Ryan Perry).
