Forewing length: male (7.6 mm). Color yellowish. Antennae whitish with indistinct, narrow annulations at intersection of antennomeres. Forewing spots not apparent (slight trace of pigmentation at base of discal and thyridial cells and base of fork V); veins of forewing chord narrowly spaced,

Setae along veins in apical part of forewing mostly apically directed, a few moderately, not conspicuously, laterally diverging. Fringe of setae along costal margin of forewing dense, short, not strongly projecting.

Preanal appendage somewhat laterally compressed, short, length about 2 times maximum width, simple in structure, apical setae elongate. Inferior appendage with prominent, very broadly rounded dorsal lobe and angularly projecting ventral lobe; projection of ventral lobe prominent and strongly protruding, forming acute angle with dorsal lobe, angle abrupt; posterior margin of ventral lobe, as viewed ventrally (Fig. 2E), very weakly bent near base, apices of paired lobes only slightly diverging; basomesal projection of appendage prominent, rounded, with short, stiff setae; dorsal lobe with stout, mesally-curved setae on dorsal margin and stout, ventrally-curved setae on mesal surface. Phallobase moderately elongate, strongly elbowed in middle, ventral apex deflexed and very distinctly projecting, ventral margin slightly convexly bulging before apex; ventral apex, as viewed caudally, narrowly U-shaped (not keeled preapically). Phallotremal sclerite prominent, basally forming very narrow, tubular collar, ventral margin projecting and broadly rounded apically; asymmetrical lateral sclerite absent.</paragraph>
