Description

From Wilson (2003): A member of the diligens group distinguished by the following combination of traits.

Major: yellow, dorsal surface of head and all of body, including gaster, virtually hairless; promesonotal profile in dorsal-oblique view 3-lobed; rugoreticulum present mesad to the eyes; sculpturing of head confined to the portion level with and anterior to the eyes; posterior half of dorsal head surface, and all of the gaster, smooth and shiny; all of mesosoma and waist foveolate and opaque.

Minor: yellow; mesosoma bare of pilosity; all of head, mesosoma and waist, along with anterior strip of first gastral tergite, foveolate and opaque.

See also Pheidole anima, Pheidole diligens, Pheidole gagates, Pheidole nubila, Pheidole piceonigra, Pheidole radoszkowskii and Pheidole stigma.

MEASUREMENTS (mm) Lectotype major: HW 1.24, HL 1.26, SL 0.74, EL 0.22, PW 0.66. Paralectotype minor: HW 0.64, HL 0.66, SL 0.66, EL 0.12, PW 0.40.

COLOR Major and minor: concolorous yellow.
