Description
From Wilson (2003): A member of the fallax group, closet to Pheidole vistana and distinguished from it and other fallax group species by the following combination of traits.
Major: head elongate, with deep occipital cleft and subangulate occipital lobes in full-face view; antennal scape exceeding the occipital lobe by 2x its own maximum width; entire body, including all of the tergites and sternites of the gaster, foveolate and opaque; space between eye, frontal lobes, and frontal carinae rugoreticulate.
Minor: entire body, including at least the anterior two segments of the gaster, foveolate and opaque; nuchal collar well developed; antennal scape very long, extending 2X the distance between its insertion and nuchal collar.
MEASUREMENTS (mm) Lectotype major: HW 1.32, HL 1.60, SL 1.42, EL 0.24, PW 0.64. Paralectotype minor: HW 0.54, HL 0.84, SL 1.20, EL 0.16, PW 0.42.
COLOR Major and minor: body concolorous medium brown, appendages yellowish brown.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
Type Material
Described from one soldier, one female and two workers taken from a single colony (No. 803) nesting under a stone at Cuernavaca, Morelos. Museum of Comparative Zoology
MEXICO: Cuernavaca, Morelos, col. Elisabeth Skwarra.
Etymology
