Gnorimoschema aterrimum

Gnorimoschema aterrimum is a moth in the Gelechiidae family. It was described by Powell and Povolný in 2001. It is found in North America, where it has been recorded from California.

The length of the forewings is about 5.1 mm. The forewings are covered by blackish scales with paler bases without a pattern. The tornal margin has a mixture of dense cinereous scales tinged with faint ochreous, extending towards the apex. The hindwings are nearly translucent, thinly blackish dusted, paler and partly lustrous basally.

The larvae feed on Solidago canadensis. They mine the leaves, creating a full-depth blotch mine.
