Proteuxoa are difficult, and especially so with P. flexirina and similar P. verecundah and similar. These species have been moved to Genus Thoracolopha which isn't on AFD yet. I think we have quite a mix of species under these two names and Proteuxoa sp that need review. There is a case for using Thoracolopha to help separate them, even though it's not on AFD.
I agree,, we need to sort these species out, being mindful of AFD (i.e is it being properly maintained?) and naming policy on the other web-based platforms.
