It doesn't matter which I search for on the RHS, it always brings up Podophyllum delavayi. Their references are a little old though and I don't know how often they update. It seems with other sources here they don't update on a regular basis but leave the name as accepted just in case it happens to change again, I know this was true of a fly on the diptera site here which lists all the present species. That doesn't however mean it is correct, the name of the fly had changed somewhere around 2005/6 and I had found a reference to it in an article. When I asked why they had not updated to the current name as recognised in Europe the reply I got was as I have said, it is left just in case it changes again and they go by the name used by the Royal Entomological Society.. I think the last update had been done around 1999!
