Agrionoptera bartola was described by Needham & Gyger 1937 based on a female from an unknown locality without a holotype being designated. Since its description no further information has become available. A comparison of the original description with specimens of A. sexlineata failed to produce meaningful characters, apart from a size difference, separating the two. Agrionoptera bartola is therefore considered a junior synonym of A. sexlineata.
