New description of male. Apical margin of tergite VIII with broad, obtusely triangular projection in almost middle half with rounded lateral angles (Fig. 18); sternite VIII elongate, rounded apically, with antecostal suture arcuate, well separated from basal margin (Fig. 19); median lobe of aedeagus with tubus short and sinuate, its subapical part narrowly elongate in lateral view, internal sac structures distinct (Fig. 17). Female. Tergite VIII with apical margin obtusely angulate, broadly rounded at middle (Fig. 20); sternite VIII shallowly, broadly emarginated medially (Fig. 21); spermatheca with a short club-shaped capsule and short apical invagination, stem long and highly sinuate (Fig. 22).
