Diagnosis.

Head, lateral sides of mesosoma and metasoma black, dorsal side of mesosoma mainly dark olive green, with slight bronze reflections; female flagellum reddish brown. Body size: 2.2-2.7 mm. Head shape in frontal view (Fig. 7A, B) slightly wider than high. Head in lateral view not unusually long, without distinct sulcus separating posterior eye margin from temple. Clypeal margin (Fig. 7A, B) convex. Supraclypeal area (Fig. 7A, B) transverse (about 1.5 × as wide as high), sides not defined; in male without oval lateral impressions. Malar sulcus versus anterior margin of malar depression shorter. Frontal keels (Fig. 7A, B) absent in both sexes. Face between scrobes and eye (Fig. 7A, B) smooth. Face between clypeus and eye (Fig. 7A, B) smooth. Lateral ocellus small (OOL at least twice the largest ocellar diameter). Funicular segments in female (Fig. 7A): most segments quadrate to transverse. Male scape (Fig. 7B) slightly widened distally; ventral pores on half scape length. Mesosoma (Fig. 7C) not narrow (less than 1.4 × as long as wide). Mesoscutum sculpture (Fig. 7C) without smooth median tubercle; interspaces smaller than punctures, smooth. Scutellum hind margin (Fig. 7C) without a double carina, without bilobed protruding projection. Prepectus (Fig. 7D) narrow, dorsal margin shorter than pronotal collar; poorly defined anteriorly (i.e. suture with pronotum indistinct); anterior margin without punctures.

Comments.

This species is closest to P. tristis (Fig. 18), based on the narrow prepectus, which is completely fused with the pronotum. The main features to distinguish both sexes of the two species are given in the key.
