Dear Pierre and Björn,
The ICZN does not regulate the position of question marks. However you can see an example of it in:
""11.9.3.4. the generic combination, although it must be unambiguous, can be tentative;
Example. In the binomen Dysidea? papillosa Johnston, 1842, the tentative generic combination does not affect the availability of the specific name.""
Cheers,
Patricio
