Therophilus wannai Sharkey sp. n. Figure 14

Diagnosis.

MT2 with short longitudinal striae restricted to transverse depression. Mid femur mostly melanic, pale apically. Fore tarsus mostly pale, melanic basally. Pronotum mostly melanic but with a pale spot dorsomedially.

Description.

Body length. 3.8 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 several pits forming a semicircular area.

Mesosoma. Number of pegs on mid tibia = 6. Number of pegs on hind tibia = 8. Sclerite between metasoma and hind coxa narrow with a high ridge along most or all of its length. Length-width of hind femur 0.823/0.256 = 3.2. 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 short 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 distinctly wider apically than basally. Ratio of widest point of MT1 to narrowest point 0.437/0.281 = 1.6. Length-width ratio of MT1 0.702/0.437 = 1.6. MT2 with short longitudinal striae restricted to transverse depression. Ovipositor much longer than metasoma, about as long as body or longer.

Color. Melanic except as follows: mouthparts mostly yellow; fore and mid femora and tibiae yellow-brown, mid leg noticeably darker than fore leg; hind tibia yellow at mid length and basally, melanic apically and subbasally; 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. Fore tarsus mostly or entirely pale. Pronotum mostly melanic but pale dorsomedially. MT2 entirely melanic.
