Pheidole macropsHNS new species

Types Mus. Comp. Zool. Harvard.

etymology Gr macropsHNS, large-eyed.

Diagnosis A member of the " bicarinataHNS complex" of the larger piliferaHNS group, comprising agricolaHNS, aureaHNS, barbataHNS, bicarinataHNS, centeotlHNS, cerebrosiorHNS, defectaHNS, gilvescensHNS, macclendoniHNS, macropsHNS, marcidulaHNS, paiuteHNS, pinealisHNS, vinelandicaHNS, xerophilaHNS, yaquiHNS, and yucatanaHNS ( macropsHNS is closet to yaquiHNS), which complex is characterized by the large to very large, forward-set eyes of both castes; and, in the major, the occipital lobes usually lacking any sculpturing; the posterior half of the head capsule almost entirely smooth and shiny; and the postpetiolar node seen from above oval, elliptical, or laterally angular (cornulate in cerebrosiorHNS). P. macropsHNS is distinguished within the complex by the following combination of traits.

Major: reddish brown; sides of pronotum longitudinally carinulate; posterior half of dorsum of head sprinkled with sparse foveae; propodeum spines relatively long and thin; apex of petiolar node in side view evenly rounded; postpetiolar node from above oval. Minor: dorsal margin of petiolar node seen from behind rises to a peak; propodeal spines vertical. Measurements (mm) Holotype major: HW 1.14, HL 1.30, SL 0.60, EL 0.22, PW 0.56. Paratype minor: HW 0.52, HL 0.56, SL 0.46, EL 0.16, PW 0.30. color Major: concolorous medium reddish brown, tarsi yellow.

Minor: body and mandibles blackish brown to black, legs and antennae medium to dark brown.

Range Known only from the type locality.

biology The type colony was collected from a ground nest in sandy desert (Philip S. Ward).
