Pheidole simoni

Nothing is known about the biology of .

Identification
Eguchi (2001) - This species is very similar to Pheidole rinae but distinguished from the latter by the dorsal outline of head in profile, condition of frontal carina, and sculpture of dorsum of head and lateral face of promesonotum.

Distribution based on Regional Taxon Lists

Worker
Eguchi (2001) - Major (lectotype). HL 1.00 mm; HW 0.84 mm; SL 0.43 mm; FL 0.55 mm; CI 84; SI 51; FI 65. Head in full-face view broadest at about 3/5 distance of head (from anterior margin of clypeus to posterior margin of occipital lobe) (Fig. 16A), in profile with an inconspicuous impression on vertex (Fig. 16B); anteroventral margin of cranium bearing 3 median processes (median one lowest). Clypeus with an evanescent median longitudinal carina. Eye situated at about 1/3 distance of head; distance between mandibular insertion and anterior margin of eye ca. 1.6 times as long as maximal diameter of eye. Frontal carina and antennal scrobe present only around antennal insertion. Masticatory margin of mandible with apical and preapical tooth, and a distinct teeth in front of basal angle. Antenna with a 3-segmented club; terminal segment ca. 1.2 times as long as preceding two segments together. Promesonotum forming a high dome, in profile with a distinct prominence on its posterior declivity (Fig. 16C); dorsal portion of the dome weakly produced laterally. Mesopleuron with a slight transverse impression; lower part of mesopleuron slightly marginate dorsally. Propodeal spine triangular, ca. 2 times as long as diameter of propodeal spiracle. Petiole ca. 1.8 times as long as postpetiole; petiolar node high, in posterior view not emarginate at apex. Postpetiole ca. 1.6 times as broad as petiolar node, angulate laterally. Frons and gena longitudinally rugose, with very weakly punctured enclosures; dorsal face of occipital lobe reticulate, with enclosures punctured weakly and dull; dorsolateral part of head above eye punctured and dull; lateral face of occipital lobe rugose, with interspaces smooth and shining; dorsal face of promesonotum slightly reticulate, with enclosures punctured and dull; the remainder of alitrunk largely punctured and weakly shining; dorsum of petiolar pedicel smooth and shining; the remainder of petiole, and postpetiole punctured and weakly shining; gaster smooth and shining.
