ID: Forewing pale sandy brown to reddish ochreous, with blackish dusting and streaks. Form brevilnea (= "short line") has a black basal streak, missing in form senelinea (= "obsolete line"). Fairly straight, transverse, antemedian and more disrinct curved postmedian lines of neural dots. Forewing longer in female than male. Antenna: according to MBGBI10, fasciculate in male, finely ciliate in female - but as far as I can see it is also bisetose in both sexes.
