[1] All junior synonyms of Ectropis use G. crepuscularia as type species, and thus, even though this large genus might warrant subgeneric division, no names are presently available.

Apart from Tephrosia, established by Jean Baptiste Boisduval in 1840, the synonyms are also junior homonyms and consequently completely invalid.

Gistl was unaware that Jacob Hübner had described the genus Ectropis, but he knew of Boisduval's Tephrosia.

He chose Coenobita, which to his misfortune had been given to a genus of hermit crabs by Pierre André Latreille in 1829 already.

That group is now included in Hypomecis, which thus has become the type genus of the tribe Boarmiini in the geometer moth subfamily Ennominae.
