Therophilus chiangmaiensis Sharkey sp. n. Figure 7

Diagnosis.

Hind tibia mostly melanic with pale coloration restricted to the medial surface at midlength. Wings relatively deeply infuscate.

Description.

Body length. 4.6 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 a deep sculptured semicircular pit.

Mesosoma. Number of pegs on mid tibia = 5. 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 1.0/0.351 = 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. Point of notauli intersection heavily sculptured over a wide area with a median longitudinal ridge. Metapleuron with white setae of moderate density.

Metasoma. MT1 with narrowly-spaced, longitudinal striae, with some microsculpture between striae, and with and two pairs of slightly stronger striae (carinae). MT1 distinctly wider apically than basally. Ratio of widest point of MT1 to narrowest point 0.6/0.357 = 1.7. Length-width ratio of MT1 0.77/0.6 = 1.3. MT2 entirely smooth. Ovipositor much longer than metasoma, about as long as body or longer.

Color. Melanic except as follows: mouthparts mostly yellow; mid and hind tibial spurs yellow; hind tibia with a yellow patch medially at mid length; anterior metasomal laterotergites and sternites mostly pale yellow; fore wing infuscate, more so than other species in this revision. Tegula black, concolorous with mesoscutum. Ocellar triangle melanic, concolorous with remainder of vertex. Hind tibia mostly melanic with pale coloration at midlength at least medially. MT2 entirely melanic.
