These new records clearly illustrate the current difficulties in assigning some specimens to an unambiguous morpho-species and suggest that there is more to learn about the occurrence of this genus in
and further work is obviously required. Molecular data would obviously be very useful in sorting out the current uncertainties about the status of these morphospecies.
