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.
