This information is based upon various sources, but no personal knowledge. I am indebted to the late Alan Horowitz for his compilation, and to Dr. J. Pachut.
I would be grateful for corrections to, or critical reviews of this information. This is not a 'final' version (an impossible ideal), but a working document.
A large number of species in this list probably are not related to the type species: some may be be allied to Aimulosia.
