1c upper-surface corridor, wholly in the leaf => 5

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

2a several whorls on top of each other with mined leaves: Aulagromyza galii

2bno vertical connection between the whorls => 3

3a larva: rear spiraculum with 4-5 papillae: Ophiomyia galii

3b rear spiraculum with > 15 papillae => 4

4a larva: last segment, behind the rear spiracula, with an unusual, sac-like extension: Aulagromyza orphana

4b no such extension: Aulagromyza lucens

5a larva: rear spiraculum with 13-15 papillae: Galiomyza morio
