Pheidole ulothrixHNS new species

Types INBio.

Etymology Gr ulothrixHNS, woolly haired, referring to the hairs on the mesosomal dorsum.

Diagnosis A medium-sized light brown (major) to yellow (minor) species distinguished in the major by curved, subrecumbent hairs (hence "woolly" hairs) all along the mesosomal dorsum; longitudinal carinulae covering all of the head except the occiput, midclypeus, and frontal triangle; lack of rugoreticulum anywhere; and broadly oval postpetiolar node.

Similar to delicataHNS, but delicataHNS has longer pilosity, none of which is "woolly," shorter propodeal spines, narrow petiolar node apex, and other details in body form, sculpturing, and pilosity as shown. See also the less similar alticolaHNS, chalcaHNS, and hazenaeHNS.

Measurements (mm) Holotype major: HW 0.98, HL 0.96, SL 0.58, EL 0.12, PW 0.46. Minor: HW 0.50, HL 0.54, SL 0.54, EL 0.10, PW 0.30.

color Major: gaster light brown; rest of body, as well as appendages, medium to dark yellow. Minor: gaster brownish yellow, rest of body medium yellow, appendages light yellow.

Range Atlantic slope of Costa Rica (J. T. Longino 1997).

biology Inhabits wet forest (Longino 1997).
