Ectoedemia terebinthivora is a moth of the Nepticulidae family. It is only known from Greece (Ionian and Aegean islands) and Turkey (Anatolia). The wingspan is 4.1-5.2 mm. Adults are on wing from June to July and from May to June. There are probably two generations per year. The larvae feed on Pistacia terebinthus. They mine the leaves of their host plant. The mine consists of a strongly contorted gallery with a narrow line of brown frass. Later, the mine widens into an elongate, irregular blotch with dispersed brown frass.
