Specimen Labels

At Cuzco Amazonico, near Puerto Maldonado, Madre de Dios, Peru, Stefan Cover and John Tobin found a population of capillata colonies in a grassy clearing on the Madre de Dios River. The nests were in heavy clay, and the workers were observed foraging on cloudy days and at dawn and dusk. The species was absent from the adjacent rainforest. (Wilson 2003)

  • capillata. Pheidole gertrudae subsp. capillata Emery, 1906c: 151 (s.w.) BRAZIL. Raised to species: Wilson, 2003: 536.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


From Wilson (2003): DIAGNOSIS Close to Pheidole gertrudae (q.v.), and possibly synonymous with it, but differing in the following combination of traits.

Major: propodeal spines present but only as short, thick denticles; frontal lobes covered by longitudinal carinulae; and thinner petiolar node in side view.

MEASUREMENTS (mm) Lectotype major: HW 1.56, HL l.60, SL 0.84, EL 0.22, PW 0.74. Paralectotype minor: HW 0.64, HL 0.70, SL 0.78, EL 0.14, PW 0.42.

COLOR Major: body mostly light yellowish brown with a slight reddish tint; gaster medium yellowish brown with reddish tint to plain medium brown.
