Aristotelia penicillata is a moth of the family Gelechiidae. It was described by Walsingham in 1897. It is found in West Indies, where it has been recorded from Haiti.[1]
The wingspan is about 10 mm. The forewings are ochreous, mottled with greyish fuscous and metallic steel-grey, with creamy-white streaks and spots. An oblique greyish-fuscous patch, edged with blackish scales externally, extends from the base of the costa nearly to the dorsum and is immediately followed by a triangular whitish streak of equal length. Two small whitish spots on the costa beyond it are followed around the termen by short streak-spots through the terminal cilia and two small black dots lie on the cell, the first at one-half, the other at its end. The steel-grey mottling appears to accompany the paler markings, except in the case of one patch near the tornus. A rosy tinge appears beyond the edge of the cell and between the black dots upon it. The hindwings are pale grey.[2]
