Hi Eric, Congrats on your flock of Physopyxis ! They are a neat and interesting doradid. I had maintained a group of them that I collected in the Rio Negro in Brazil a number of years ago. But no breeding. When you get home you might want to dig into the taxonomic weeds a bit in that in addition to ...

Hi Eric,
Looks like you are having a good time!
First batch of photos - picture number three - small doradid. Looks like a Physopyxis species to me.
This is an edit...I goofed ("adult"): the 5 mm size that you provided is even smallish for the genus Physopyxis.

HH - thanks for the follow-up. I guess, from what you say, that there is a bit of a mess for the authors to straighten out.
Lee

Hi HH. Thanks for posting a note on the availability of this open access paper. I have a couple of questions that you can no doubt answer: On page 17, under the "Supplementary Material" section is the following note - "...ventral view of Tachysurus nicholsi sp. nov.,...". It is l...

Hi Eric,
Looks like you are having a wonderful fish-time!

I haven't pulled out the paper as of yet but the caudal pattern on the first Otocinclus certainly brings to mind the species O. batmani.

Hi all.

The two new species in the paper are named:
Hypophthalmus celiae Littmann, Lundberg & Rocha.
Hypophthalmus donascimientoi Littmann, Lundberg & Rocha.

One follow up clarification on Lujan's comment regarding the priority of the new Tribe name Brachyglaniini: Nathan "...assumed..." that the Silva et al. paper would have it. Sorry if I overstated it in my last post.

Lee

Eric: Thanks for adding in the additional material. I did get a copy of the paper this morning and am working through it and comparing with the Silva et al. paper that you had covered. Kind of in the same ball park, but some variance between the two. It will be interesting to see how all shakes down...

Follow-up to original post: This paper and one posted in this forum earlier today by Eric (Evolutionary history of Heptapteridae) make for an interesting clash (or maybe crash) of science. I have not seen the full version of this paper yet (only the abstract) so any strong comparison is not possible...

Hi Eric,

Fast for putting in the new species...good!

The website I mentioned with the incorrect author placement for T. humboldti was the World of Fishes.

When I finish here a copy of the paper will be heading your way. Enjoy!

A quick follow-up on my initial mention of the usage of the species names musaica and musaicus in the abstract: In the body of the full paper one of the species names ( musaica ) is used incorrectly on one occasion (page 150). It is used correctly on page 163. The name musaicus is used correctly on ...

Thanks Eric. The same pic was on the Zootaxa site, but I didn't mention it due to lack of defining info...as with the recent Corydoras description.

Hi Steve,
Thanks for dropping in on the thread...it is only fitting that you should at least do a guest appearance. Congrats on being part of the team that produced an interesting and enjoyable paper.
