Therophilus apichati Sharkey sp. n. Figure 4

Diagnosis.

MT2 pale in anterior half, melanic posteriorly. Ocellar triangle melanic, concolorous with remainder of vertex.

Description.

Body length. 2.6 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 23. Posterior surface of scutellum mostly smooth, posterior scutellar depression well-defined by two large pits separated by a short longitudinal ridge.

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 0.596/0.24 = 2.5. 2nd submarginal cell reduced to a small dot, petiole longer than cell is high, or large, cell height subequal to petiole length. Hind wing vein Cub emanates from near mid length of apical margin of subbasal cell, Cub short and weak. Point of notauli intersection heavily sculptured over a wide area. Median lobe of mesoscutum not bulging and not sharply declivous anteriorly. Metapleuron with scattered white setae.

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 0.32/0.22 = 1.5. Length-width ratio of MT1 0.44/0.32 = 1.4. 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 black except as follows: antenna brown, palpi, labrum and other mouthparts yellow, tegula yellow, fore and mid legs entirely yellow, hind coxa mostly black, hind femur mostly brown, paler apically, hind trochanter, tibia, and tarsus mostly yellow, metasomal mediotergite yellow in a nterior half or more, anterior metasomal laterotergites and sternites pale yellow. Tegula yellow, contrasting with predominantly black mesoscutum. Ocellar triangle melanic, 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. MT2 pale in anterior half, melanic posteriorly.
