Diagnosis
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.
Discussion
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
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 in Mexico and A. collinsii in Costa Rica and Panama.
