9b puparium shining black; front spiracula not penetrating: Cerodontha incisa
10a puparium monochromous; front spiraculum indistinctly bifid: Chromatomyia nigra
10b puparium ventrally with a dark length band; front spiraculum fist-shaped: Chromatomyia fuscula
11a larva whitish; rear spiraculum shaped like a boat hook: Cerodontha calamagrostidis
