 Hi Shyamal, thanks for quickly pulling out references. There seems to be many name suggestions (valappannayan, kundan karawila from your source, olaippambu, ...) floating around. It looks like what we used to call, in our coconut-groove rich region, olaippambu (perhaps alluding to dried coconut leaves) and Ayyappan Kutti for whatever reason. Two traits: it being mistaken for the Common Krait and many snakes of the species seen in the vicinity of each other stand out in my memory. I wanted the Tamil Vernacular names for the Tamil Wiki article on Batesian mimicry. -)   \ \
