Frons brownish (Fig. 7G). Pedicel brownish yellow; first flagellomere yellow (Fig. 7G). Clypeus entirely brownish yellow. Palpus brownish (Fig. 7G). Mesonotum mostly brownish yellow (Fig. 7H). Postpronotal lobe yellow (Fig. 7I). Acrostichal setulae in ca. 12–14 irregular rows (Fig. 7H). Scutellum mostly brownish yellow, brownish laterally, yellow at tip (Fig. 7H). Pleura with a brown to dark brown, longitudinal stripe above (Fig. 7I). Katepisternum and mesopleuron mostly yellow (Fig. 7I). Wing (Fig. 3F): brownish distally; costal vein between R 2+3 and R 4+5 distally with ca. 5–7 peg-like spinules on ventral surface; R 4+5 and M 1 slightly divergent distally; halter mostly yellowish, with a brownish to brown patch at knob (Fig. 7I). Abdominal tergites brown to dark brown, 2nd tergite yellow anteromedially and laterally, 3rd tergite mostly yellowish except for lateral region, setigerous laterally and on posterior margin in males (Fig. 10I), 3rd and 4th tergites anteriorly yellow in females (Fig. 10J). Male terminalia: Epandrium lacking pubescence, with ca. 10 setae near posterior and ventral margins per side (Fig. 29A). Cercus lacking pubescence (Fig. 29A). Surstylus pubescent (Fig. 29A).
