This is not original thought on my part - more a summary of
the set theory work of Marc Geoffroy which seems to cover
all eventualities.

Without being able to cite a real example, I can imagine
a situation where you are dealing with homonyms - they
have exactly the same names, at least as far as genus and
species components go, but apart form that, concept-wise,
not even the type is in common.  This could be an
example of a non-intersection that is not a
misidentification; both are acceptable concepts but
according to the rules, only one can validly bear the

yes... or it could simply be a 'misidentification' and you
thought it was something else...  :)

Thinking of it another way - the concept could be including
the type but you are using the wrong concept...
no, this never happens in taxonomy... :)

pretty sure this will be the most common situation...
