Description
From Wilson (2003): A member of the aberrans group, closest to Pheidole minensis and Pheidole obscurifrons.
Major: light yellow; frontal lobes seen from the side form prominent lobes that only partly overhang the clypeus; seen from above, the lobes are broad, and subangular at their anterior tips, which extend to within an Eye Length of the anterior clypeal border; tips of frontal lobes smooth, which surfaces are succeeded posteriorly by a broad band of carinulae, and this gives way at eye level to a smooth area that extends all the way to the occiput; pronotal profile semicircular; faint carinulae line the lower pronotal margin.
Minor: pronotum covered by semicircular carinulae, and mesopleuron by foveolae and longitudinal carinulae.
MEASUREMENTS (mm) Lectotype major: HW 1.42, HL 1.64, SL 0.58, EL 0.18, PW 0.84. Paralectotype minor: HW 0.80, HL 0.80, SL 0.58, EL 0.12, PW 0.48.
COLOR Major: concolorous light reddish yellow.
Minor: body light brown, appendages brownish yellow.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
