DESCRIPTION OF MALE

Head

Head including eyes narrower than mesonotum; greenish ochraceous with the following marks: three black spots enclosing each ocellus, fused at center, not reaching frontoclypeal suture or posterior margin of head; three longitudinally arranged pairs of fuscous spots between the three fused spots and eye, of which lowest pair are largest. Gena greenish ochraceous without mark. Postclypeus moderately swollen; light green with indistinctly fuscous fasciae along anterior five or six transverse grooves. Anteclypeus ochraceous without distinct marks. Rostrum ochraceous, but black apically; with tip reaching or passing posterior margin of sternite I.

Thorax

Thorax ochraceous. Inner area of pronotum with a pair of central longitudinal black fasciae, with their anterior ends widened laterad, and black to fuscous irregular marks widespread over inner area. Pronotal collar very narrowly margined with brown to fuscous fascia and with a pair of indistinctly fuscous postero-sublateral patches. Lateral pronotal collar not dentate but waved. Mesonotum with the following black to fuscous marks: longitudinal median fascia extending posteriad to reach anterior margin of cruciform elevation, of which anterior half indistinct; large spot on posterior half of each submedian sigilla; irregular and indistinct spots on each lateral sigilla; a pair of large spots broadly enclosing scutal depressions; a pair of larger spots on posterolateral corners of mesonotum. Cruciform elevation greenish ochraceous with anterior subapical parts black. Thoracic sternites ochraceous without marks.

Wings

Wings hyaline and tinged with green. Fore wing with infuscation irregularly on every cell, including small infuscation present on each hind margin of radius posterior (RP), median, and cubitus anterior (CuA) veins.Venation brown basally and light green distally. Basal membrane and hind wing jugum light grayish ochraceous.

Operculum

Operculum ochraceous; about as long as wide, nearly rectangular with edges rounded, but lateral side elongated anteriorly; scarcely extending beyond posterior margin of sternite II. Two opercula apart from each other, with gap of about width of operculum. Meracanthus ochraceous.

Abdomen

Abdomen cylindrical, about 1.67 times (n = 1) as long as head and thorax together; brown without distinct marks except for fuscous posterior margin of tergite 2. Posterior margin of tergite 3 much wider than mesonotum. Timbal cover very short, semi-oval, much wider than long, revealing timbal in dorsal view. Male abdominal sternite III with tubercle-like projection on each centrolateral surface. Abdominal sternites ochraceous, densely covered with white pollinosity.

Genitalia

Pygofer long, elliptical in ventral view. Distal shoulder not pointed. Uncus not bifurcate, short, standing at about 60 degree to pygofer in lateral view. Basal lobes of pygofer absent. Aedeagus thick, with lower end partly expanded.
