Hey,

Baryancistrus xanthellus = L 18, L 85, L 177
It seems that L 81 has to wait some more time for it´s description.

and as you said:

Baryancistrus chrysolomus = L 47

Anyone else struggling to download off their site?

I'm getting 3kb/sec max, and then it just keeps dropping out. Frustrating.

Yes, it took me an eternity as well. Do you want me to e-mail you the 13.6MB file?

Given the size and problems in downloading this Baryancistrus paper, and as it's open access anyway, I have uploaded the paper here.

I hope this is not in breach of copyright, and I will take it down if there are any problems.

Will do the Trachycorystes one too, if that ever finishes downloading ...

I feel that the omission of was simply an oversight on the author's behalf. Having read the description, I can't see any reason why L081 cannot be included under Baryancistrus xanthellus.

Me too. For me, all 4 should be the same sp.

I have sent an e-mail to Lucia Rapp Py-Daniels to ask about L081. I do expect it still belongs in this group.

Hmmm, except the paper does explicitly mention l-numbers and, given the authors participation (and copious note taking) at the inaugural l-numbers convention, I find it hard to see it as an oversight.

I'd say L081 is a B. sp. cf. xanthellus for now.

Any response yet Mats?

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.
Rapp Py-Daniel et al. wrote:Considerable variation in density and size of spots.
.

For me this suggests L081 should be included in B. xanthellus.

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 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

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