Cnephasia microbathra, also known as the brown shouldered leaf-tyer, is a species of moth of the family Tortricidae. It was first described by Edward Meyrick in 1911 but the placement of this species in the genus Cnephasia is in doubt. This species is endemic to New Zealand and has been observed in both the North and South Islands. It inhabits damp native forest or habitat near watercourses. The larvae feed on species of fern in the genus Cyathea. They fold and tie fern fronds together with silk to create a shelter. The adult moth is on the wing commonly from September until February. This species is regarded as being rare.
