The wedge-tailed jery (Hartertula flavoviridis) is a small bird endemic to the east of Madagascar. The species has been the cause of some taxonomic confusion, it was originally placed with the jeries in the genus Neomixis (Cisticolidae) before being placed in its own monotypic genus Hartertula, but still considered close to Neomixis. Recent research indicates it is part of an endemic Malagasy radiation currently known as the Malagasy warblers (Cibois et al. 2001).
