DESCRIPTION OF MALE

Head

Head slightly wider than base of mesonotum; brown with the following black marks: median

mark scarcely enclosing ocelli, with its anterior end reaching frontoclypeal suture and its lateral ends extended towards eyes; a pair of indistinct spots on anterolateral corners. Distance between lateral ocelli and eyes about 1.5 times as wide as distance between lateral ocelli. Postclypeus moderately swollen; greenish ochraceous with marks indistinct. Anteclypeus ochraceous with a pair of fuscous spots. Rostrum with apex not reaching posterior margin of hind coxae. Lorum ochraceous with fuscous spot along inner margin. Gena brown with small fuscous spot between postclypeus and eye.

Thorax

Pronotal collar with lateral margins concave, not dentate; light green with very narrow fascia along posterior margin, broadened laterally. Inner area of pronotum brown with the following marks: a pair of antero-submedian triangular marks; a pair of postero-submedian triangular marks; a pair of large elliptical mark taking almost one fourth of inner area. Mesonotum ochraceous with the following black to fuscous marks: median longitudinal narrow fascia, widened posteriorly; a pair of small roundish spots enclosing scutal depressions; a pair of narrow fasciae along inner parts of parapsidal sutures; a pair of longitudinal fasciae on lateral sigilla, much widened posteriorly and reaching posterolateral corners of mesonotum. Cruciform elevation greenish ochraceous.

Wings

Wings hyaline with marginal areas very narrow. Fore wing M2 derived from u2; M4 derived from u3; length between bifurcation point into M and M1 + 2 and bifurcation point into M and M3 + 4 2.0 times or more the length between bifurcation point into M and M3 + 4and base of M; basal portion of RA2 about one fourth as long as longitudinal portion of RA2; basal portion of RA2 forming an angle of about 135 degrees to longitudinal portion of RA2. Fore wing with infuscations on r, r-m, m, and m-cu and bases of RA2 and M1. Linear infuscation present on each hind margin of RP, M1-4, and CuA1, and CuA2. R + Sc ochraceous or greenish ochraceous. Basal membrane and hind wing jugum gray.

Operculum

Operculum greenish ochraceous without marks; very short, not reaching posterior margin of sternite II, oblique, parallelogram-like, with corners rounded. Opercula apart from each other, with gap about as wide as operculum.

Abdomen

Abdomen distinctly longer than head and thorax together. Tergite 4 wider than other tergites. Tergites brown to dark brown with yellowish sublateral and lateral parts on tergites 2, 3, 4, 5, and 6. Timbal fuscous; very small, semicircular. Timbal exposed. Ventral part of abdomen ochraceous to brown.

Genitalia

Pygofer narrow, elliptical in ventral view. Distal shoulder angled. Uncus not bifurcate. Uncal lobe simple, with widened subapex and slightly incised apex. Basal lobe of pygofer with dull apex and with spine-like small protrusion subapically. Aedeagus moderately slender and moderately protruding.
