Jacobsoni are nearly round, while destructor
are ellipical in shape. Destructor is also larger
(when comparing adults to adults).

This semi-famous set of mug shots has appeared all

A very nice side-by-side comparison.

Also, the abstract of the paper that presented "varroa"
as being more than one mite is here:

This is a lousy image, but I am assuming that you'd rather
have something than nothing:
