L081 are from the lower Xingu at Porto de Moz, right? The study didn't sample that far downriver, but it's strange they didn't mention this L number, or discuss the possibility of unsampled populations and intraspecific variation.

L081 is much more widely spread in Xingu, lower Xingu, Altamira and even a variety at Sao Felix we call Stardust (same size of spots as all other L081 but lighter).
I just think they overlooked this L-number, maybe they didn't know the localities.

I've about given up trying to access this paper online. I can get to page 6, but it takes forever ... and then stops downloading before page 7. Can anyone forward me a copy of the Baryancistrus xanthellus paper?

I uploaded the paper to a better server on the first page of the thread. Have a look through my posts.

I tried that link, and my computer just spun its wheels for a long time and nothing happened. Technology is, evidently, a woman: can't live with it, can't live without it.

Hi!!

It went vastly unoticed because of the problem acceding the papers, but Hypoptopomatinae sp. (LG2) has been described in this volume as well as Otothyropsis piribebuy from what I could read on L-welse.com

Cheers

Yes, the name LG2 is even mentioned in the paper itself!

Hi!!

Thanks to confirm it...I still tried to opened it but never could reach to a fully downloaded version, but I highly suspected it was mentionned in the description!!
Cheers

Otothyropsis piribebuy.

Why did you list it as Otothyris? It has been described as Otothyropsis, or do you see last one as a synonym? And the text in "Identification" should be changed.

I read it too fast and though it was the genus with the fewer letters. Fixed that now. We didn't have Otothyropsis in the database either, so there wasn't anything to alert me to my mistake it (and I have to say I was unfamiliar with that genus).

Hey Jools,

allright, I just got a bit confused about this. There is one more species: Otothyropsis marapoama.

On the L081 debate I'm assuming you've seen the Glaser email Newsletter which discusses L081n the Sao Felix variant and states they think it is different to xanthellus (mainly) based on adult colouration, but they include L081 as xanthellus. Photos of different stages of the Sao Felix/Stardust variant are included, notably an adult.

Hi Steve

Yes, I saw that. I'm including the brownish l081 in l081 which I am not content is within the range of the description. I plan to change l081 to B. cf. xanthellus.

Based on the description etc I still think L081 is xanthellus, but I now accept the Sao Felix variant is probably a different species, based on the adult ccolouration.

Here is a Sao Felix/L081n taken at Pier Aquatics:
