Therophilus wongchaii Sharkey sp. n. Figure 15

Diagnosis.

Ocellar triangle melanic, contrasting with remainder of vertex, or pale, concolorous with remainder of vertex. Tegula yellow, contrasting with black lateral lobes of mesoscutum. Hind tibia largely pale, melanic apically and with a subbasal melanic band or lateral spot, or mostly pale, melanic apically only.

Description.

Body length. 3.5 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 29. 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 0.850/0.298 = 2.9. 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 extending past meeting point but sculpture not extending over a wide area.

Metasoma. MT1 length distinctly longer than apical width. MT1 with narrowly-spaced longitudinal striae, with some microsculpture between striae, and lacking two pairs of distinctly stronger striae (carinae). MT1 not distinctly wider apically than basally. Ratio of widest point of MT1 to narrowest point 0.4/0.311 = 1.3. Length-width ratio of MT1 0.642/0.4 = 1.6. MT2 with transverse and/or diagonal striae in and/or near transverse depression. Ovipositor much longer than metasoma, about as long as body or longer.

Color. Orange, yellow, black, and brown; head mostly orange, ocellar triangle melanic; antenna melanic; mesoscutum mostly pale medially, melanic laterally; prothorax yellow; meso and metapleuron and propodeum melanic; fore and mid legs yellow; hind leg brown except trochanter and most of tibia yellow; metasomal mediotergites mostly melanic except base of MT1 and all of MT2 yellow; anterior metasomal laterotergites and sternites pale yellow, remainder of metasoma melanic; fore wing weakly infuscate. Scape entirely melanic. Tegula yellow, contrasting with predominantly black mesoscutum. Ocellar triangle melanic, contrasting with remainder of vertex, or pale, concolorous with remainder of vertex. Hind tibia mostly pale, melanic apically and with a subbasal melanic band or lateral spot, or mostly pale, melanic apically only. Fore tarsus mostly or entirely pale. MT2 entirely melanic, or pale in anterior half, melanic posteriorly, or entirely or almost entirely pale.
