What Scobinancistrus is this?

Does anyone know what Scobinancistrus is this? L-48 or 362 or 368? Are they all S. pariolispos?

It is a nice aquisition whatever this fish turns out to be.

The only real difference between these L-numbers and S. parliospos is their capture location. L362 is from Rio Jamanxim, which is a tributary to Rio Tocantins.

From the pictures here, L368 appears to have much larger spots, but it could be that it's just a juvenile - just like young L14's have larger spots than mature adults...

The best way to determine which L-number (or species) of the fish is to know the capture location. Really good wholesalers (and thus shops buying from those wholesalers) will be able to tell you which river the fish came from, but most won't

Most pics of Scobinancistrus species that is not S. auratus avaliable are juvenilles with large and/or few spots, and they seem to get more spots with increasing size. Anyone has pics of adult L-362 or L-368?

Yes, both Scobinancistrus and Baryancistrus seem to have a "higher number of smaller spots" as they grow older.

Searching the Web for L368 images only reveals the ones in the Cat-eLog, so I guess there aren't that many.

DATZ says that the L368 is from Rio Tocantins, so the same general area of Brazil, but not the same river as S. parliospos or L362.

http://www.transfish.de has a picture of L362, but it looks like the same fish as the L362 picture in the Cat-eLog (and the one in DATZ).

That's the reason why I ask here

L-48 seems to be from Xingu, so S. pariolispos may be just the L-362 and L-368 if there is any real difference between them. That doesn't help id the fish in question though, since white/light yellow or light orange spots version of juv L-48 seems similar to juv L-362 and L-368...

Yes, I understand why you ask, and I would also agree that they are most likely the same species. But until some scientist has actually compared them and written a scientific paper on the subject, we can't say for sure.

Of course, even if they are the same species, there may be a good reason to not "mix them" if you plan on breeding them - just like different forms of other fish shouldn't really be mixed - Tropheus are one of those that have many different colour forms within a species, and in my opinion, they should be bred within their own form.

The problem is that there is no way to get locality of this Scobinancistrus from the seller, and I would like to find where are they from... Is there any way to differentiate L-48 from L-362 or L-368?

+++addition+++ After checking Rio Jamanxim flows into Tapajos, So it may be possible that L-362 is the same as L-368? Since L-48 is from Xingu does this mean S. pariolispos from Rio Tocantins has not yet been exported?

One of these appeared at LFS recently. Came in with and named a 'Goldie'.
I actually ID it as L253, what do you think?[img]/Users/andrewcoffey/Desktop/1.jpg[/img]
