Pheidole hazenaeHNS new species

Types Mus. Comp. Zool. Harvard.

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 PheidoleHNS ants will continue to exist.

Diagnosis A medium-sized, yellow member of the flavensHNS group, similar to 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 alticolaHNS, euryscopaHNS, heterothrixHNS, rectilumaHNS, rectisentisHNS, rectispinaHNS, and rectitrudis, and notably different in others as illustrated. Minor: not diagnosed.

Measurements (mm) Holotype major: HW 0.86, HL 0.90, SL 0.46, EL 0.10, PW 0.40. COLOR Major: concolorous yellow.

Range Known only from the type locality and a single Colombian accession (Zona Buenos Aires, 600-800 m, Charles Kugler). In the second series the specimens are larger and darker than the type and may represent a distinct species.

biology Zona Buenos Aires, Colombia: in second-growth forest.

figure Unique holotype, major. ECUADOR: Rio Palenque Station, 47 km south of Santo Domingo, Pachincha (Stewart B. and Jarmila Kukalova-Peck). Scale bar = 1 mm.
