Therophilus sukpengae Sharkey sp. n. Figure 13

Diagnosis.

MT2 smooth in most of anterior half anteriad transverse groove, longitudinally striate in transverse groove and area posteriad transverse groove, at least medially. Tegula black, concolorous with mesoscutum.

Description.

Body length. 3.9 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 27. Posterior surface of scutellum posterior scutellar depression represented by two pits.

Mesosoma. Number of pegs on mid tibia = 4. Number of pegs on hind tibia = 9. Sclerite between metasoma and hind coxa narrow with a high ridge along most or all of its length. Length-width of hind femur 0.8/0.266 = 3.0. 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. Point of notauli intersection heavily sculptured 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 one pair of distinctly stronger striae (carinae). MT1 distinctly wider apically than basally. Ratio of widest point of MT1 to narrowest point 0.383/0.263 = 1.5. Length-width ratio of MT1 0.61/0.383 = 1.6. MT2 smooth in most of anterior half anteriad transverse groove, longitudinally striate in transverse groove and area posteriad transverse groove, at least medially. Ovipositor much longer than metasoma, about as long as body or longer.

Color. Body mostly melanic, legs mostly pale; body melanic except as follows: mouthparts yellow, tegula brown, fore and mid legs mostly yellow except coxae melanic, basal half of femora brown and apex of tibiae and some tarsomeres light brown, hind tibia mostly pale except apex and a light brown subbasal lateral spot, all tibial spurs yellow; anterior metasomal laterotergites and sternites pale yellow; fore wing weakly infuscate. Tegula black, concolorous with mesoscutum. Ocellar triangle melanic, concolorous with remainder of vertex. Hind tibia mostly pale, melanic apically and with a subbasal melanic band or lateral spot. Pronotum entirely melanic. MT2 entirely melanic.

Etymology.

Named in honor of Ms. Acharaporn Sukpeng collector for the TIGER project at Chae Son National Park.
