Macropiratidae is a family of moths which has sometimes been treated as a subfamily of the Pterophoridae, owing to the resemblance between specimens of Macropiratidae and plume moths of the genus Agdistis, at least when preserved as pinned specimens. The family contains a single genus Agdistopis with three species. Thomas Bainbrigge Fletcher described the species now known as Agdistopis sinhala from a single specimen in poor condition, collected in Sri Lanka in December 1907.
