I have not checked all the IDs yet, though I suspect that specimens of Caenoplana coerulea are unlikely to be misidentified. Most folk get the ID right for this well-known and common species. One of the difficulties that I had with species information was deciding whether to log it as invasive - which it is overseas, or non-invasive. Technically it is invasive outside Queensland as it has a long history of distribution via the nursery industry. The species might occur naturally in northern NSW. The same may apply to Caenoplana bicolor, another Queensland species, though there is some question that it and another species from NSW are conspecific. All rather confusing at present, so I will let sleeping dogs lie.
I think if its from another part of Australia we tend to mark it as non-local native, Cootamundra wattle is a good example of that, and the Invasive category is for invasive exotic species. It may be worth noting under the species description if it had become invasive elsewhere. So far your info in the species descriptions has been fantastic, its great to have that level of information for us to learn by. I wish we had that level of information for every species on CNM, but perhaps that will come in time as this database develops even further.
