These ones with small eyes belong to the subgenera Tavandra or Hesperandra, which differs in the presence (or absence) of a intergenal ridge on the ventral side of the head. I need a picture of this particular.

According to me, they are two females of Hesperandra (Tavandra) polita (Say, 1832).
You can check by yourself the key by Santos-Silva (2003).
The species is largely widespread in Central and Southern America.

Yes, this key is very clear and makes it evident.
Thank you, Francesco.
