notes

In a botanical garden pulla sometimes co-occured on Genista with A. johannae. The mines of the two are indistinguishable (Hering, 1957a). To judge by the drawing by de Meijere (1925a), the distal tooth of the mandible of johannae stands off at a right angle. This might separate it from A. pulla, that is depicted with the distal tooth clearly recurved. It remains to be seen if this distinction is constant; moreover, the drawing of pulla was based on a second instar larva.
