Pheidole laevinota

From Wilson (2003): The Horco Molle series was collected in subtropical evergreen forest, and includes a male (19–22 January).

Identification
See the description in the nomenclature section.

Distribution
From Wilson (2003): Recorded by Kempf (1972a) from São Paulo and Jujuy, northern Argentina. I have verified another Argentine record, from near Horco Molle, Tucumán, 750–900 m (W. L. Brown).

This taxon was described from Brazil.

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.
