Hi!

Seems that L121 has a name (or even two...)
I dont know where Stawikowski caught their original L121 so both could be...

L305 comes from the Takutu River, so it would be P. braueri. If the L121 picture by Stawikowski in the transfish website is the original one, then L121 is also P. braueri.

The pictures of L121 in the Cat-eLog appear to be P. cavatica instead.

Who says L135 is from the Demini and not the Branco? Maybe it's from both, certainly DATZ appears to imply this?

Unfortunately we don't know what Peckoltia cavatica (BTW, IMHO not the greatest name for a fish that belongs to a whole tribe / sub-family of cave spawners.) looks like when young.

Oddly there is a Peckoltia (L265) from the Tapajos that looks a lot like P. cavatica too - the main exception being the light network pattern on the snout.

I'm going to lump all three l-numbers into P. braueri and shift what I currently have as L121 to the new species although I have a significant worry that the two fish look very similar as youngsters and only age makes them look different. Thus L135 really could be the new species but I'm betting against it mainly because of another worry. Namely either the paper appears to only have touched on female or immature P. cavatica or they do not share the same odontodal growth as everything else traditionally known as Peckoltia, L135 certainly gets a bit "hairy" so, I'm going with the lumping for now.

The pterotic-supracleithrum would be on the back of the head, towards the side. It would be somewhere at the same level with or slightly above, and behind the eye.

Thanks for your reply Jools .

I can see the situation is not exactly clarified within this group ...

Anout L135 available for the aquarium trade, I'm sure at least one part comes from Rio Deminias as I witnessed piabeiros catch some there. They locally call it bodo cara de mapa
