The genus is most closely related to "Ligustrum" (privet), classified with it in Oleaceae tribus Oleeae subtribus Ligustrinae.

Gracillaria albicapitata Gracillaria albicapitata Gracillaria albicapitata is a moth of the Gracillariidae family. It is known from the islands of Hokkaidō and Honshū in Japan and the Russian Far East. The wingspan is 9.8-12.5 mm. The larvae feed on "Fraxinus lanuginosa", "Fraxinus mandshurica", "Syringa amurensis", "Syringa reticulata" and "Syringa vulgaris". They mine the leaves of their host plant. Young larvae mine directly into the middle layer of the parenchymal tissue of the leaf or leaflet. The mine made by the larvae of the first three instars is irregularly large blotchy or wide linear, and inter-parenchymal, with a few weak wrinkles on both
