What is it about Samui that all the recent new species I find are stated by C&P to be rare, there are plenty of common species which should be on the Island which I have yet to find. In this case it states that all members of the genus are very rare.
This is Deramas livens livens (Pisuth says D. livens evansi, but I think that the two are synonymous). SK may have seen it before, I don't think many others of you will have done so. I hope you enjoy - I did!
