Worker diagnosis. - A medium-sized member ( HW ca. 0.75-0.98) of the P. sericeus  group, with large elongate eyes ( REL ≈0.65), convex median clypeal lobe, subcontiguous frontal carinae ( MFC ≈0.02), and palp formula of 6,4. Head longer than broad (Cl≈0.85). Basal face of propodeum shorter than declivitous face and meeting the latter at an angle. Petiole short, high ( PLI > 1.00), with sharp dorsolateral margins; in profile anterior and dorsal faces of petiole weakly differentiated, rounding sharply into the vertical posterior face (Fig. 2). Body with fine punctulate-coriarious sculpture, opaque. Standing pilosity very sparse; a pair of stout setae present on the pronotal humeri, petiole, and postpetiole. Dark brown-black, with lighter brown maculation variably present on the pronotum, petiole, postpetiole, fronto-clypeal complex, and appendages.

Taxonomic comments. - This is one of several species originally described as “varieties” of P. sericeus (Mayr)  . Workers of P. ita  can be distinguished from those of P. sericeus  by the angulate shape of their petiole, especially in lateral view (Fig. 2); the petiole of P. sericeus  is subtriangular in profile, with more gently rounded edges.

Distribution and biology. - P. ita  occurs from Mexico to Colombia, and typically inhabits dead twigs or branches of various woody plants. It has been collected from thorns of Acacia cornigera View Cited Treatment   in Mexico and A. collinsii View Cited Treatment   in Costa Rica and Panama.
