Hi Sandra Do you have some expertise that you know for sure that this is Caenoplana coerulea? We have no-one with enough knowledge of worms etc, so would respect your choice.
This medium blue colour variant of Caenoplana coerulea is peculiar to the Kosciusko area - the dorsal ground colour is almost the same as the cobalt-blue ventral surface. Normally the species is described as being Prussian blue in colour.
Thanks for all your work on these flatworms and the extra information as well. It fascinating and very difficult information to come by. I don't suppose you have considered writing a book?
Yes, the thought has crossed my mind, but trying to sort out some of the pressing taxonomic problems in the Australian land planarian fauna, and finishing off my work on land planarians of the NZ Subantarctic Islands have priority :)
