The Autostichidae are a family of over 300 species of small moths in the superfamily Gelechioidea. They were established as a distinct family by Ronald Hodges in 1986 and occur worldwide, mainly in the Nearctic, Palearctic, Australian, and Polynesian regions, with highest diversity in xeric (dry) habitats of the Mediterranean and eastward.

Adults have wingspans of 8–20 mm, with slender bodies and wings held roof-like at rest; many show subtle metallic or patterned markings. They are mostly nocturnal or crepuscular. Larvae are typically detritivores, feeding on dead or decaying plant and animal material, such as lichens, leaf litter, or even dung; some mine leaves or bore stems, with reduced stemmata and case-making habits in certain subfamilies.

The family includes subfamilies like Symmocinae (170+ species in 42 genera, xeric-adapted), Oegoconiinae (18 species in 7 genera), and Holcopogoninae (120+ species in 18 genera). Common genera include Meleonoma (e.g., 16+ species in China), Symmoca, and Holcopogon. Recent studies continue to describe new taxa, especially in Asia and the Neotropics.
