Atasthalistis tricolor is a moth in the family Gelechiidae. It was described by Cajetan Felder, Rudolf Felder and Alois Friedrich Rogenhofer in 1875.[1] It is found in Indonesia (Sulawesi, Java), the Solomon Islands[2] and Australia, where it has been recorded from the Northern Territory.[3]
The wingspan is about 22 mm. The forewings are blackish fuscous with a broad very pale whitish-yellowish streak along the costa from the base to near the apex, leaving the costal edge narrowly blackish from one-fourth onwards. The lower edge of this streak is shortly indented before the middle and there is a pale whitish-yellowish line along the hind margin from above the apex to below the anal angle, externally margined with a few black scales. The hindwings are bright orange.[4]
