Original description, Turner 1917
Maroga leptopasta, n. sp.
λεπτοπαστος, lightly sprinkled.
♂ 46-50 mm. Head whitish. Palpi dark-fuscous. Antennae dark-fuscous, paler towards apex; in ♂ shortly laminate and minutely ciliated. Thorax grey, tegulae whitish. Abdomen fuscous, bases of segment suffused with ferruginous; three basal segments grey; tuft and apices of lateral marginal hairs ochreous; underside whitish. Legs fuscous; posterior tibiae, and posterior surface of middle tibiae ochreous; middle and posterior tarsi annulated with whitish. Forewings sub-oblong, costa straight, apex rounded-rectangular, termen scarcely oblique, rounded beneath; grey-whitish very sparsely irrorated with large single black scales; sometimes a black discal dot at 2/3; cilia whitish, sometimes with a few black scales. Hindwings somewhat prominent at tornus; whitish; cilia whitish.
Near M. setiotricha Meyr., but smaller, .the forewings whiter, the irroration much more sparse , and yet coarser. M. paragypsa Low., which I have not seen should be distinguishable by the long yellowish hairs on hindwings.
N.A. Port Darwin in February; two specimens received from Mr. G.F. Hill.
