MALE.—Color pale greenish, fading to pale brown; forewing with an indication of light fuscous shading along chord. Length of forewing 13–15 mm.

Malar space narrow, about height of eye. Parafacial and postocular areas about width of malar; postocular area with a row of 5–7 setae. Maxillary palpus with apical segment length of basal 4 segments combined. Process of fifth sternum large, ovoid (like that of championi).

Genitalia: Tenth tergum with warts, a, b1, and b2 arising close together at apex of tergum, each on a short stalk; lateral lobe bluntly pointed apically, posterior face broad and rather strongly sclerotized. Clasper with apical segment elongate, terete; basal segment almost 4 times as long as apical, base unmodified. Phallobase elongate, sharply angled; apex with process b finger-like, erect; c shorter, twisted; e fused to phallobase, in form of an elongate row of spicules ending in a rounded lobe dorsolaterally; g a membranous, rounded, ventrolateral lobe; j elongate, forked apically, arms of fork as long as basal stem.
