Therophilus boonthami Sharkey sp. n. Figure 6

Diagnosis.

Ocellar triangle melanic, contrasting with remainder of vertex, which is pale. Hind tibia mostly melanic, pale color restricted to extreme base.

Description.

Body length. 3.3 mm.

Head. Space between antennal insertions with a weakly developed bulge that is weakly declivous posteriorly, dorsal surface of bulge with a shallow longitudinal groove. Number of flagellomeres 28. Posterior surface of scutellum posterior scutellar depression represented by two pits.

Mesosoma. Number of pegs on mid tibia = 5. Number of pegs on hind tibia = 9. Sclerite between metasoma and hind coxa narrow, and lacking a high ridge along its length. Length-width of hind femur 0.755/0.31 = 2.4. 2nd submarginal cell large, cell height subequal to petiole length. Hind wing vein Cub emanates from near anterior apex of apical margin of subbasal cell, Cub long and weak. Notauli meeting but sculpture not extending outside of well-defined grooves.

Metasoma. MT1 length only slightly longer than apical width. MT1 with narrowly-spaced longitudinal striae, with some microsculpture between striae, and lacking two pairs of distinctly stronger striae (carinae). Ratio of widest point of MT1 to narrowest point 0.481/0.338 = 1.4. Length-width ratio of MT1 0.55/0.481 = 1.1. MT2 entirely smooth. Ovipositor clearly shorter than body, about as long as Metasoma.

Color. Mostly yellow or yellow-orange with some brown and black; head yellow or orange except antenna, vertex, and occiput brown; thorax yellow or orange and brown, darker near crenulae and sutures; propodeum mostly dark brown; fore and mid legs yellow; hind leg mostly yellow except most of tibia and tarsus melanic, hind tibial spurs yellow; metasoma mostly yellow; posterior terga mostly brown, MT1 with some weak melanic color on longitudinal striae; fore wing weakly infuscate. Tegula yellow, contrasting with predominantly black mesoscutum, or yellow or orange, similar in color to predominantly orange or yellow mesoscutum. Ocellar triangle melanic, contrasting with remainder of vertex. Hind tibia mostly melanic, pale color, if present, restricted to extreme base. MT2 entirely or almost entirely pale.
