Best confirmed by dissection. Aproaerema anthyllidella is similar as are other small dark gelechiids with some form of pale markings on the costa as detailed below.
A few similarly-sized Gelechiid species have this combination of dark forewing and whitish yellow tornal and costal spots. The colouration of the labial palps are one of the more useful features to aid determination.
nb - labial palp (lp) segment one is very short (difficult to see) and tucked back below the eye, segment two is broader and extends forward to a position in front of the base of the face, segment three is thin and needle like curving up in front of the face.
Oxypteryx atrella - lp segments 1, 2 and 3 obviously ochreous with the lower edge in segment 3 narrowly fuscous (blackish brown). Forewing has apical quarter with a purple sheen.
Oxypteryx immaculatella - lp segment 1 dark fuscous and segment 2 greyish white above and on sides, dark fuscous below. Slightly smaller species with diffuse or absent (when worn) paler forewing markings.
Aproaerema anthyllidella - lp segment 1 purplish-fuscous, segment 2 variable in extent of buffish-white and purplish-fuscous and segment 3 buffish-white with outer edge purplish fuscous. The forewing often has yellowish ochreous scales in the fold (lower central part of the forewing at one-third). This species has a dark cilia line obvious in fresh specimens, absent in Eulamprotes spp.
Aproaerema sangiella - lp segment 1 purplish-fuscous, segment 2 inner surface buffish white, outer surface has a variable mix of darker and lighter scales and segment 3 inner surface buffish white, outer surface purplish fuscous. Generally a larger moth.
Aproaerema albipalpella (rare) - lp segment 2 has white ring at apex. A small species.
