Antenna with scape, pedicel and first flagellomere yellow, flagellomeres two to four bicolored, black basally and yellow apically, rest of flagellomeres uniformly black ( Fig. 24 View Figures 24–29 ); prescutum gray with three brownish gray stripes, scutum yellowish brown, each lobe with two pale brown areas ( Fig. 3 View Figures 1–6 ); wing obscure brown with dark stigma, R 1+2 entire, petiole of cell M 1 distinctly shorter than discal cell ( Fig. 24 View Figures 24–29 ); abdominal tergites with indistinct lateral and median dark stripes ( Fig. 24 View Figures 24–29 ), hypopygium brownish black.

Redescription of hypopygium. Tergite nine medially separated, protruding into a pair of horn-shaped processes in lateral angles, a pair of angular arms arising from the ventral surface of tergite nine, the arm with a truncated process directed inward ( Fig. 25 View Figures 24–29 ); sternite nine with caudal margin rounded, ventral surface bearing two strands of long hairs ( Fig. 26 View Figures 24–29 ); gonocoxite elongate, separated from sternite nine, gradually narrowed to apex, paliform apically, a finger-like process generated from base of gonocoxite in ventral view ( Fig. 26 View Figures 24–29 ); outer gonostylus narrow, filiform ( Fig. 27 View Figures 24–29 ); inner gonostylus equipped with black beak at apex, with two narrowed processes at dorsal margin ( Fig. 27 View Figures 24–29 ).

Semen pump with compressor apodeme V-shaped, forming a 90° angle with posterior immovable apodeme ( Figs 28–29 View Figures 24–29 ). Posterior immovable apodeme shorter than compressor apodeme, gradually narrowed to apex in lateral view ( Fig. 29 View Figures 24–29 ). Anterior immovable apodeme equal in length to posterior immovable apodeme, gradually narrowed to terminus ( Fig. 29 View Figures 24–29 ).
