Sharkey, Michael J. & Stoelb, Stephanie A. C., 2012, Revision of Therophilus s. s. (Hymenoptera, Braconidae, Agathidinae) from Thailand, Journal of Hymenoptera Research 27, pp. 1-36 : 9-10

Therophilus areeluckae Sharkey sp. n. Figure 5

Diagnosis.

MT2 smooth in most of anterior half anteriad transverse groove, longitudinally striate in transverse groove and area posteriad transverse groove, at least medially. Mid femur mostly pale with a bit of melanic color at extreme base. MT2 entirely melanic. Similar to Therophilus rugosiferus but Therophilus areeluckae has no transverse ridge on the propodeum, more sculpture on mesoscutum, and the fore and middle legs are paler.

Description.

Body length. 4.0 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 rugose over a semi-circular area that represents the scutellar depression.

Mesosoma. Number of pegs on mid tibia = 5. Number of pegs on hind tibia = 9. Sclerite between metasoma and hind coxa wide with a high ridge along most or all of its length. Length-width of hind femur 0.815/0.256 = 3.2. 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 anterior apex 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.

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 0.414/0.278 = 1.5. Length-width ratio of MT1 0.668/0.414 = 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 black except as follows: antenna brown, palpi, labrum and other mouthparts yellow; tegula yellow; fore and mid legs yellow except for mostly melanic coxae; hind coxa, trochanter, and femur black; hind tibia mostly pale yellow, melanic apically and with a very weak patch of light brown sub-basally; hind basitarsomere mostly yellow, remaining tarsomeres mostly melanic; anterior metasomal laterotergites and sternites pale yellow; fore wing weakly infuscate. Scape entirely melanic. 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. Fore tarsus mostly or entirely pale. Pronotum entirely melanic. MT2 entirely melanic.
