Alaska has no snake species, in fact it has no reptile species at all. Hawaii has no native land dwelling reptile species, including snakes, but it has a well established, (likely) introduced snake species, the Island Blind Snake. There is also a sea snake. Hawaii also has several introduced lizard species. As far as snakes in the contiguous US, I would guess that Maine or another Northern New England state has the fewest species. Wyoming also has relatively few.
