Figs 109–112

Diagnosis

The female of S. regina sp. nov. can be separated from that of all other species by the combination of the following characters: S6 bifid posteriorly, apical notch about as long as its apical width ( Fig. 110C ); metasoma partially red ( Fig. 109B ); fore tibia and tarsi completely or largely red ( Fig. 109A ); head wider than long, vertex flat ( Fig. 109C ); T5 apically without hair fringe ( Fig. 110B ); head and mesoscutum with short golden hair ( Fig. 109C–D ); propodeum sparsely covered with golden hair ( Fig. 110A ). The male can be separated from that of all other species by the combination of the following characters: body length 4.9 mm; metasoma at least partially red ( Fig. 111B ); fore tibia and tarsi completely red ( Fig. 111A ); metapostnotum glabrous and shiny ( Fig. 111E ); Head and mesosoma with relatively short golden and white hair ( Fig. 111C–D ); wings slightly yellowish, almost clear ( Fig. 111A ).

Etymology

The species looks like a queen (Latin: ‘ regina ’) because of the golden ‘crown’ hairs on the female vertex. Noun in apposition.
