A.conterminella is similar. It is separated in the key in MBGBI4.1 by having the tegulae concolorous with the thorax (the colour of both varying from pale buff to brownish fuscous). The text also mentions that the underside of S2 of labial palp is pale buff in A.liturosa and brownish fuscous in A.conterminella. The tegulae of A.liturosa are described as "dark purplish brown paling posteriorly to pinkish-brown or sometimes buff".
Most web images labelled as A.conterminella show a transverse basal demarcation between a pale forewing base and the dark purplish subbasal area; while most web images labelled as A.liturosa show the entire base of the forewing and the tegulae dark purplish.
