Pheidole peregrina Wheeler View in CoL   HNS

Pheidole peregrina Wheeler   HNS 1916p: 181. Syn: Pheidole impariceps   HNS Santschi 1923d: 47, n. syn.; Pheidole impariceps var. fusciclava   HNS Santschi 1923d: 48, n. syn.

Types Mus. Comp. Zool. Harvard.

Etymology L peregrina   HNS , traveling, foreign. Referring to discovery of the type colony on a floating log.

Diagnosis A small, yellow member of the diligens   HNS group whose major has posterior two-thirds of head capsule smooth and shiny, rugoreticulum present as a small patch just mesad to the eye, moderately abundant pilosity, and short equilaterally triangular propodeal spine in side view.

Similar to blumenauensis   HNS , laevifrons   HNS , mooreorum   HNS , rochai   HNS , and vafra   HNS , differing in many details of body form, sculpturing, and pilosity, as figured.

See also the somewhat less similar lemur   HNS , pubiventris   HNS , seeldrayersi   HNS , spilota   HNS , variegata   HNS , venatrix   HNS , and zelata   HNS . Measurements (mm) Lectotype major: HW 1.00, HL 1.06, SL 0.74, EL 0.14, PW 0.56. Paralectotype minor: HW 0.54, HL 0.64, SL 0.76, EL 0.14, PW 0.36. color Major: concolorous dark yellow.

Minor: head light brownish yellow, rest of head and appendages clear dark yellow.

Range Known from several localities in Sao Paulo state.

biology 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   HNS [ peregrina Wheeler   HNS ] 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   HNS , like the anatomically similar and widespread vafra   HNS , is a specialist in marginal habitats. The types of the synonymous impariceps var. fusciclava   HNS were collected on another island in the same area, Ilha dos Alcatrazes.
