It seems to me like an imbalance of some sort. According to the way you stated it here your calculations should be correct. Buy it and when it finally rebalances, sell it or create some kind of spread.

If the other strike prices are in line you could create a spread right away and lock in the difference.

My guess is that the option ask probably is higher and that 16.10 was the "last transaction price" so look at the bid and ask prices because that's what you have to buy it at. If this is not the case buy it and pm me what it is so I can buy it too
