Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Description
A medium-sized, yellow member of the flavens group, similar to Pheidole camilla but differing in the major caste in the moderately convex profile of the head (not bulging as in camilla), exclusively carinulate (as opposed to partly rugulose and rugoreticulate) sculpturing of the dorsal head surface, and the vertical, forward-curving propodeal spine as viewed from the side.
At 50–60X the tips of the mesosomal and gastral hairs are not flattened as in camilla. Also similar in some features to Pheidole alticola, Pheidole euryscopa, Pheidole heterothrix, Pheidole rectiluma, Pheidole rectisentis, Pheidole rectispina and Pheidole rectitrudis, and notably different in others as illustrated.
Minor: not diagnosed.
MEASUREMENTS (mm) Major: HW 0.86, HL 0.90, SL 0.46, EL 0.10, PW 0.40.
COLOR Major: concolorous yellow.
Figure. Unique holotype, major. Scale bars = 1 mm.
Type Material
ECUADOR: Rio Palenque Station, 47 km south of Santo Domingo, Pachincha, col. Stewart B. and Jarmila Kukalová-Peck. Museum of Comparative Zoology
Etymology
Named in honor of Anne-Eve Hazen, in recognition of her outstanding contribution in service and support to tropical conservation, hence the habitats in which the Pheidole ants will continue to exist.
