Diagnosis.

Head black, upper face and vertex with blue green or bronze green reflections; mesosoma dorsally bronze green, occasionally dark bronze or with slight violet reflections; female flagellum brown. Body size: 2.50-3.25 mm. Head shape in frontal view (Fig. 9A, B ) much wider than high. Head in lateral view not unusually long, without distinct sulcus separating posterior eye margin from temple. Clypeal margin (Fig. 9A, B ) truncate. Supraclypeal area (Fig. 9A, B ) strongly transverse (at least 1.5 × as wide as high), sides well defined; in male without oval lateral impressions. Malar sulcus versus anterior margin of malar depression shorter. Frontal keels (Fig. 9A, B ) absent. Face between scrobes and eye (Fig. 9A, B ) slightly striate. Face between clypeus and eye (Fig. 9A, B ) slightly striate near anterior margin of malar depression. Lateral ocellus large (OOL less than twice the largest ocellar diameter). Funicular segments in female (Fig. 9A ): most segments quadrate to transverse. Male scape (Fig. 9B ) slightly widened distally, ventral pores on more than half scape length. Mesosoma (Fig. 9C ) not narrow (less than 1.4 × as long as wide). Mesoscutum sculpture (Fig. 9C ) without smooth median tubercle; interspaces smaller than punctures, rugose. Scutellum hind margin (Fig. 9C ) without a double carina, with large bilobed protruding projection. Prepectus (Fig. 9D ) wide, dorsal margin longer than pronotal collar; well defined anteriorly (i.e. suture with pronotum very distinct); anterior margin without punctures.
