Description
From Wilson (2003): Similar to Pheidole coffeicola, Pheidole laevifrons, Pheidole pubiventris, Pheidole rufipilis and Pheidole variegata (= Pheidole pubiventris), but especially to Pheidole rufipilis, a partially sympatric species from which it differs as follows.
Major: rugoreticulum present posterior-laterad to antennal fossa; front and lateral margins of pronotum carinulate, but pronotal center smooth and shiny; upper side of propodeum carinulate; postpetiolar node from above oval; humerus in dorsal-oblique view subangulate.
Minor: humerus in dorsal-oblique view angulate; pronotal dorsum smooth.
MEASUREMENTS (mm) Holotype major: HW 1.18, HL 1.16, SL 0.86, EL 0.20, PW 0.58. Paratype minor: HW 0.54, HL 0.64, SL 0.74, EL 0.14, PW 0.40.
COLOR Major: body light brown, appendages dark yellow.
Minor: concolorous light brown.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
Type Material
BRAZIL: São Paulo, S. P. Musee d'Histoire Naturelle Genève - as reported in Wilson (2003)
Etymology
L laevinota, smooth notum, evidently in contrast to that of Pheidole rufipilis. (Wilson 2003)
