Cedoaphis

Cedoaphis Oestlund

This is a group that seems almost certain to be more complicated and speciose than is currently understood.  Blackman and Eastop note that there are two species that are likely not truly congeneric.  I agree that C. maxsoni and C. incognita are likely not closely related, but I think there are at least two species lumped within C. incognita.  The fundatrices of the species on Symphoricarpos are highly specialized and have been confused with Aphthargelia in the past, probably due to uncertainty as to what each would look like in the fundatrix stage.  Further, the dogma put forward in Blackman and Eastop and elsewhere that the fundatrix lives on the roots in C. incognita is obviously not the case for the Cedoaphis I get on Symphoricarpos.  This is yet another example of a situation where concerted study of my own samples might lead to an interesting paper, if only I (or perhaps you?) put the time into it.
