Comments. This is the first record of Pheidole bufo for Colombia. It was previously known for French Guiana, Ecuador, and Brazil (Wilson 2003). The image of a paratype minor worker on AntWeb (CASENT0624236) has the face largely smooth and shining between sparse longitudinal carinulae. In contrast, the only specimen from the Colombian Amazon has the face with dense shallow punctuation between the carinulae. In dorsal view of the gaster, that paratype (CASENT0624236) with the dorsum of the first tergite completely smooth, while the specimen from Colombia has the first tergite with short faint longitudinal costulae extending from the base to 1/4 of the length of the tergite.
