Two new species of gelechiid moths from the genus Stegasta Meyrick, 1904, S. variatensis sp. n. and S. pallidula sp. n., are described from Papua-New Guinea and Sumatra Island, Indonesia. The forewing pattern of the new species is very similar to that of S. variana Meyrick, 1904 from Australia and S. parki M. Omelko & N. Omelko, 2020 from Laos. In the male genitalia, the new species are similar to both S. parki and S. variana in that the cucullus has a large beak-shaped process and, besides, with the former by claw-like apex of the cucullus. They can be distinguished from S. parki by the structure of the adeagus, and from S. variana by the distal part of the beak-shaped process on the cucullus, which is not narrowed before the acute apex, and by the claw-like apex of the cucullus, which is rounded in the latter.
