Diagnosis.

Head and mesosoma green, with bronze gold reflections; metasoma blue green; female flagellum dark brown, ventrally reddish-brown. Body size: 2-3 mm. Head shape in frontal view (Fig. 4B) much wider than high. Head in lateral view not unusually long, without distinct sulcus separating posterior eye margin from temple. Clypeal margin (Fig. 4B) slightly emarginate. Supraclypeal area (Fig. 4B) slightly transverse (less than 1.5 × as wide as high), sides slightly defined; in male with oval lateral impressions (Fig. 4B). Malar sulcus versus anterior margin of malar depression shorter in female. Frontal keels (Fig. 4B) absent. Face between scrobes and eye (Fig. 4B) striate. Face between clypeus and eye (Fig. 4A, B) almost smooth. Lateral ocellus large (OOL less than twice the largest ocellar diameter). Funicular segments in female (Fig. 4A): most segments quadrate to transverse. Male scape (Fig. 4B) strongly widened distally, ventral pores on nearly all scape length. Mesosoma (Fig. 4C) not narrow (less than 1.4 × as long as wide). Mesoscutum sculpture (Fig. 4C) without smooth median tubercle; interspaces smaller than punctures, smooth. Scutellum hind margin (Fig. 4C) without a double carina, with small more or less bilobed protruding projection. Prepectus (Fig. 4D) wide, dorsal margin longer than pronotal collar; well defined anteriorly (i.e. suture with pronotum very distinct); anterior margin without punctures.

Comments.

The female of P. aureoviridis can be confused to those of P. laevifrons and P. masculinus; it can be distinguished from those mainly by the larger interspaces on mesoscutum and scutellum (Fig. 4C) and the entirely green body, with slight golden or bronze reflections (Fig. 4A). The males of P. aureoviridis should be easily recognizable being the only ones with oval lateral impressions adjacent to the supraclypeal area and ventral pores on nearly all scape length (Fig. 4B).
