Its not a L48 or L253 in fact its not even the Scobinancistrus species...
you can tell from the eye.. its not golden.... that pleco's eyes are black.. I would venture to say its either a Snowball pleco OR that could actually be a Gold nugget.. without the yellow tip colors...
All Scobinancistrus have very distinctive eyes.. very yellow gold with a bit of white.. make you think it has cloudy eyes because that species is very unique..
I have two species with me.. L48 and L14.. anyways.. need a better picture of the mouth.. i can tell by the mouth shape..
