Geographic range. Colombia.

Comments. This is a large species known from montane forest sites in the cordillera just east of Bogotá. The holotype came from a nest series that contained the only known Adelomyrmex males. A distinctive feature of A. vaderi is that the postpetiole is long and narrow in dorsal view, longer than wide, and projecting posteriorly over the gaster. In this regard it is similar to A. silvestrii . In contrast to A. silvestrii, the postpetiole is tall, with the posterodorsal projection higher and not closely appressed to the gaster.
