The species we now call
Mycophaga testacea (Gimmerthal, 1834)[Anthomyiidae] was originally described by Gimmerthal in the genus
Coenosia. It should not be confused with
Coenosia testacea (Robineau-Desvoidy, 1830) [Muscidae] which was originally described in the genus
Palusia.
The name
Musca pulchella was used by Fabricius for the species we now call
Hemilea dimidiata, but he thought he was describing the
Musca pulchella of Rossi (which we now know as
Palloptera muliebris (Harris)). The name is a misidentification, and thus unavailable, and although it predates Costa's name, cannot be used, so is a synonym.
Hemilea dimidiata (Costa, 1844) is the correct name.
I do hope I've got that right! :)
The Cybernome site does not a give a source for its insect taxonomic information, so i can't comment on why it does not agree with the current thinking on this synonymy.
