Thorax:
Head:
Colour:
Yellowish brown, antennae brown
Antennae:
Scape and pedicel short, as long as wide, covered with setae. Flagellum cylindrical, densely covered with fine setulae, tapering toward apex, with 14 flagellomeres. Ratio of length to width for the first flagellomere is 4.5, for the flagellomeres 2 to 8 is 2.3.
Mouthparts:
Clypeus rounded and setose. Mouthparts and palpi yellowish brown. Palpi with 4 palpomeres, covered with dark setae. Palpomere 4 (apical) narrow and somewhat darkened. Relative length of palpomeres 1 to 4: 1:2:3.2:3.6.
Thorax:
Notum:
Mesonotum yellowish brown, with three longitudinal dark stripes, which are covered with dark setae. Lateral margins of mesonotum also darker and setose. Scutellum brown, with several long dark apical bristles. Mediotergite bare, yellowish brown
Lateral sclerites:
Laterotergites and preepisternum 2 bare, yellowish brown. Anepisternum with about 10 black setae near upper margin. Antepronotum with 4 black setae.
Halters:
Yellowish, covered with dark setulae.
Wings:
Venation:
Costa produced beyond R5. Sc ending in C before base of Cu-fork. Sc2 absent. R1 ending in C well beyond base of M-fork. Veins R-M and bM-Cu in one line.
Setation:
A1 setose
Sizes and ratios:
Ratio of wing length to width 2.6. Ratio of the length of R1 to the total wing length is 0.67. M ratios: 0.54 and 0.71. Cu ratios: 0.63 and 1.38. A1 reaching wing margin.
Wing base:
Calypter well developed, bearing long setae along its margin.
Legs:
Colour:
Yellowish
Setation and ornamentation:
Legs covered with dark trichia and setae. All coxae with a longitudinal row of black setae, c1 anterolaterally, c2 laterally and c3 posterolaterally. Femora clothed with numerous trichia and with a row of longer setae ventrally.
Shapes and Ratios:
Femora laterally compressed and thickened medially. Fore and mid femora somewhat longer than coxae, hind femur almost twice as long as hind coxa. Ratio of the spur length to the length of the first tarsomere for legs are: 0.23; 0.26; 0.31. All spurs on mid and hind tibiae subequal in length. Ratio of femur (including trochanter) to tibia for legs: 0.83; 0.86, 0.75. Ratio of tibia to tarsus: 0.62; 0.87; 1.17. Ratio of first tarsomere to tarsus: 0.50; 0.52; 0.52.
