I would be carefully to say it is spec. “Sentang”. Parosphromenus spec. “Sentang” are from Sentang and traded some years ago in a very large size. This is a sign that the area of Sentang get an infrastructure. Certainly these area used to become a land of plantations. That is the only one reason for constructing infrastructure on Sumatra. So one can suspect that in the area of Sentang can’t find Parosphromenus since three or four years after it became a land of plantations.
It is definitely a problem with kinds of Parosphromenus like this one that we can’t say what is is exactly. But I think that the original spec. “Sentang” from three or four years are extinct in nature!
