TYPE SPECIES. — Chlorops denticornis Panzer, 1806

REMARKS

The genus Cerodontha is classified into seven subgenera ( Butomomyza Nowakowski, 1967, Cerodontha, Dizygomyza Hendel, 1920, Icteromyza Hendel, 1931, Phytagromyza Hendel, 1920, Poemyza Hendel, 1931, and Xenophytomyza Frey, 1946). All subgenera have been recorded in the Neotropical region, except for Phytagromyza, which is exclusively Holarctic. The species are quite variable externally, but the male genitalia is characteristic with a well-developed mesophallus and long tubular distiphallus. In addition, all species in the genus Cerodontha have in common an L-shape sclerite inside the epandrium (the subepandrial sclerite or “Langfortsatz” of previous authors). A single specimen of Cerodontha was collected on the Mitaraka massif and belongs to the subgenus Dizygomyza . This subgenus is characterized by a large lunule and typically an enlarged first flagellomere in the male, although there are a few exceptions, including the new species described below.
