Diagnostic features

Fluviopupa gracilis is separated from F. ramsayi in having an elongate-pupoid shell, and the distal end of the penis is longer (not shorter) than the accessory lobe. In F. ramsayi ramsayi, the shell is larger than that of F. ramsayi royana and the inner lip is more closely applied to the parietal wall.
