Therophilus mellisoma Achterberg & Long, 2010

Diagnosis.

Body length 3.7 mm; ovipositor length/body length ratio = 0.64. Interantennal space with a flat triangular elevation, with a weak shallow ridge posteriorly not as elevated as the triangular elevation. Antenna with 27 flagellomeres. Third labial palpomere reduced, barely visible, much smaller than apical palpomere. Notauli pitted throughout. Scutellar groove with 3 longitudinal ridges. Fore tibia lacking spines; mid tibia with 6 pegs; hind tibia with 5 pegs. The Thai specimen in Figure 17 differs from the holotype in the lack of a melanic patch distally on hind femur.

Variation.

Color usually entirely xanthic (yellow) except for brown as follows: most wing veins including stigma, antenna, hind tarsus and apex of hind tibia. Some specimens are more melanic with brown color extending to propodeum, most of hind leg and parts of most terga.
