Completely by chance, I now have an equivalent problem in squids and cirrate octopods to chase, many of which genera end in -teuthis, for example Trachyteuthidae/Trachyteuthididae, Grimpoteuthidae/Grimpoteuthididae, Luteuthidae/Luteuthididae and so on... is there any consensus on "prevailing usage" for these, or is it going to be a case by case basis going back to the original descriptions? (I feel a trawl through BHL and Zoological Record coming up...)
Regards - Tony
