Holotype worker: Colombia , Nariño, Barbacoas, vereda Berlín, El Diviso, 520 m , 22.viii.94 (F. Escobar leg. No.294) [ICN] (not examined). Geographic range. Colombia . Comments. Adelomyrmex grandis and A. vaderi are two Colombian species that are similar in size but differ in a number of sculpture, shape, and color characters (Fernández, pers. com.). In A. grandis , the whole body is the same color, versus somewhat bicolored in A. vaderi (with lighter-colored gaster). The postpetiole of A. grandis is more typical, wider than long in dorsal view, and without a pronounced posterodorsal projection or carina in lateral view. In A. vaderi , the postpetiole is longer than wide in dorsal view, with a bluntly acute posterodorsal projection in lateral view. Also, the rugose sculpture on the face of mesosoma of A. grandis is more regular and less reticulate compared to A. vaderi . The two are geographically separate, with A. grandis being in the southwest of Colombia , on the western slope of the Cordillera Occidental, and A. vaderi in central Colombia on the eastern slope of the Cordillera Oriental.
