Dear fellow bee-listers,

perhaps someone out there with a background in mite taxonomy can help me
out as the literature I find is pretty scanty...

Are there genera closely related to Varroa? How is the family constructed?
(Varroa is one single genus with 2 species in a single family? or not?)
Are there any mites one could share or have been shared in the past within
the Varroa genus but which, for example, do not live on honeybees?

Kind regards,
Lennard
