etymology Gr macrops   HNS , large-eyed.

Diagnosis A member of the " bicarinata   HNS complex" of the larger pilifera   HNS group, comprising agricola   HNS , aurea   HNS , barbata   HNS , bicarinata   HNS , centeotl   HNS , cerebrosior   HNS , defecta   HNS , gilvescens   HNS , macclendoni   HNS , macrops   HNS , marcidula   HNS , paiute   HNS , pinealis   HNS , vinelandica   HNS , xerophila   HNS , yaqui   HNS , and yucatana   HNS ( macrops   HNS is closet to yaqui   HNS ), 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 cerebrosior   HNS ). P. macrops   HNS 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.
