Diagnosis. A small species (0.9-1.4 mm) with dark brown scape, coxae and femora (Fig. 228), female gaster elongate (1.6x as long as length of mesosoma) with apex distinctly pointed, mesoscutum and scutellum usually bicoloured in golden purple or purple metallic (occasionally golden red) and golden green or green metallic (Figs 229, 230); female flagellomeres 2-4 ventrally with one set of setae attached subbasaly and reaching beyond apex of flagellomere attached to (Fig. 236), male flagellomeres 1-4 with a basal whorl of setae and with setae reaching beyond apex of flagellomere attached to (Fig. 240), some specimens with a few setae apical to whorl. Male genitalia: phallobase (Fig. 490) with digitus triangular and 0.6x as long as wide, volsellar setae on long extensions and with apex of setae 1.4x the length of setae from apex of phallobase; aedeagus short and stout (Fig. 490), with penis valves 1.5x as long as wide.
