Description

Adult ( Figure 1 View Figures 1–3 ). Wingspan 14.5 mm in male. Forewing ground colour pale grey or silverwhite; basal fascia indistinct, shortly elongated on costa, dark brown; median fascia developed on middle of costa, forming a small rectangular spot, then very weak towards dorsum, nearly indistinct, not arcuated; pre-apical streak similar to median fascia in shape and coloration; apex more or less rounded; termen very weakly oblique. Hindwing greyish brown, rather pale grey at basal area, showing a net-like pattern in the remaining area.

Male genitalia ( Figures 2, 3 View Figures 1–3 ). Tegumen broad dorsally. Uncus atrophied. Socii not prominent, very slender, elongated. Transtilla with short and sub-triangular median process, shortly bifurcate terminally. Juxta rather small, narrow, nearly half-moon shaped, with rounded top. Valva short, rather broad at base, rounded near apex; sacculus narrowed, well sclerotized basally, reaching to middle of ventral margin of valva. Aedeagus stout, shortly pointed terminally, with numerous cornuti in vesica.

Female genitalia. Unknown.
