Description

From Wilson (2003): DIAGNOSIS A member of the perpusilla group (very small, with 10-segmented antennae), close to Pheidole perpusilla. Distinguished as follows.

Major: anterior half of dorsum of head mostly covered by longitudinal carinulae, and posterior half foveolate and opaque; propodeal spines long and backward-directed; dorsum of postpetiolar node and anterior half of central strip of first gastral tergite foveolate and opaque.

Minor: all of head and mesosoma foveolate and opaque.

MEASUREMENTS (mm) Major (Trinidad): HW 0.66, HL 0.66, SL 0.34, EL 0.08, PW 0.34. Minor (Trinidad): HW 0.32, HL 0.36, SL 0.30, EL 0.06, PW 0.24.

COLOR Major: concolorous medium yellow.

Minor: concolorous light reddish yellow.

Figure. Upper: major. Lower: minor. TRINIDAD: Blanchiseusse Road, 10 km marker. Scale bars = 1 mm.

Type Material
