Cerodontha (Poemyza) Hendel

Dizygomyza ( Poëmyza) Hendel, 1931: 35. Type species Agromyza pygmaea Meigen 1830, by original designation.

Phytobia ( Poëmyza). Frick 1952a: 391, 1959: 379.

Cerodontha (Poemyza) . Nowakowski, 1962: 102, 1967: 645, 1973: 73; Spencer 1969: 127; Spencer and Steyskal 1986b: 93.

The lunule of Poemyza is characterised as being relatively high and narrow, often being much higher than wide. This is exaggerated in many species where the fronto-orbital plate is produced over the lunule’s wider base. Some species, such as C. inconspicua (Malloch), however, have a shorter lunule similar to that of species in the subgenus Butomomyza , but the texture of the lunule in Poemyza species is pitted and bare (not flat and velvety) and the acrostichal seta is usually absent (not present). The buccal cavity between the arms of the clypeus is also densely covered with minute spicules, at least in Nearctic species, but this has not yet been confirmed for the global fauna. A similar lunule is seen in Xenophytomyza , which has a pointed first flagellomere similar to some Poemyza , but Xenophytomyza differs in lacking lateral scutellar setae.
