Description
From Wilson (2003): A member of the fallax group, similar in different characters to Pheidole bergi, Pheidole cordiceps, Pheidole nitidula and Pheidole pampana, and especially so with Pheidole nitidula, with which it may be synonymous, and distinguished as follows.
Major: concavity of occipital border very broad in frontal view; rugoreticulum less extensive on genae (than in nitidula); in dorsaloblique view, humerus lower than convexity that follows it; pronotum completely smooth and shiny.
MEASUREMENTS (mm) Lectotype major: HW 1.06, HL 1.08, SL 0.64, EL 0.20, PW 0.56.
COLOR Major: body concolorous medium reddish brown.
Figure. Lectotype, major. Scale bars = 1 mm.
Type Material
BRAZIL: Mogidas-Cruzes, São Paulo. Istituto di Entomologia "Guido Grandi" - as reported in Wilson (2003)
