Wheeler, W.M., 1916
On the type series, by Hermann von Ihering, as quoted by W. M. Wheeler (1916: 180–181): “One morning, while [Mr. Gaste, a local naturalist] was on the island of San Sebastian, he found a tree trunk that had floated to the shore during the night and was filled with a living ant-colony belonging to a species of Pheidole [peregrina Wheeler] unknown to me. San Sebastian is situated some kilometers off the coast of the mainland. Of course, we cannot say how long this log had been floating in the water before it reached the island.” It may be that peregrina, like the anatomically similar and widespread vafra, is a specialist in marginal habitats. The types of the synonymous Pheidole impariceps var. fusciclava were collected on another island in the same area, Ilha dos Alcatrazes. (Wilson 2003)
