"quantiles" is the general name. 

"quintiles" would be associated with a division 
into 5 groups. 

All the words I have heard of for other particular
cases use Latin roots. So what would it be? 

The Latin for 16 was "sedecim", so I suppose 
it would be "sedeciles". 

However, it wouldn't surprise me -- should you adopt this 
term -- if you were the first person ever to use it, and 
whenever you used it, you would have to explain it
to almost everyone. So, I would stick with quantiles
based on division into 16 groups of equal frequency, 
wordier but serviceable.
