1a full depth corridor, may end in a blotch => 2

1b epidermal corridor, or a more or less contracted blotch or tentiform mine => 6

1c galls, etc => Tables for all parasites per species

2a gallery strongly contorted at first, a blotch in the end; on P terebinthus only: Ectoedemia terebinthivora

2b gallery not that strongly contorted, nor so strongly widened => 3

3a gallery widening only a little, and gradually; first section not strikingly narrow => 4

3b first half of the gallery thin as a hair, wider only in the later section; larva yellow => 5

4a larva yellow; frass does not fill the width of the gallery; eastern Mediterranean, on P. terebinthus: Acalyptris pistaciae

4b larva green; frass occupies the width of he gallery; species not restricted to this plant, more widely distributed: Simplimorpha promissa

5a species of the western Mediterranean; on P. lentiscus: Acalyptris minimella

5b species of the eastern Mediterranean; on P. lentiscus and terebinthus: Acalyptris pistaciae

6a lower-surface, very transparant tentiform mine with clear epidermis folds; larva remains in the mine till shortly before pupation: Cupedia cupediella
