Therophilus songrani Sharkey sp. n. Figure 12

Diagnosis.

Ocellar triangle pale, concolorous with remainder of vertex. Tegula yellow or orange, similar in color to predominantly orange or yellow mesoscutum. MT1 distinctly longer than apical width.

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 = 6. Number of pegs on hind tibia = 10. Sclerite between metasoma and hind coxa narrow, and lacking a high ridge along its length. Length-width of hind femur 0.750/0.265 = 2.8. 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 barely meeting and sculpture not extending past meeting point.

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 0.367/0.264 = 1.5. Length-width ratio of MT1 0.54/0.387 = 1.4. 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. Yellow or yellow-orange except as follows: antenna melanic; thorax with melanic infusions along crenulae and sutures; propodeum mostly melanic; MT3-MT7 mostly brown; Wings hyaline. Scape entirely melanic. Tegula yellow or orange, similar in color to predominantly orange or yellow mesoscutum. Ocellar triangle pale, concolorous with remainder of vertex. Hind tibia mostly pale, melanic apically only. MT2 entirely or almost entirely pale.
