Copella sp. from Rio Tapajos

[rasmusW]

Hey all!

Can any of you wise folks help me identify the Copella sp. In this video (-about 6 min. in. Just when it clips to a school of apistos).

I know there is not a lot to go from, but I wanted to give it a shot.

As far as I can tell, Copella nigrofasciata, should occour there, but it doesn’t really look like that species, to me atleast.

Thanks in advance.

Timestamp?

Timestamp?

6:02-6:04 -ish
It darts by from left to upper middle screen.

thanks. I knew the video for a long time, but it was almost impossible to find the fish without a timestamp.

This one I presume?

My guess: C. meinkeni

Copella meinkeni - Aquarium Glaser GmbH

Diese schönen Schlanksalmler wurden in der Literatur viele Jahre als Copella nattereri bezeichnet, bis in einer wissenschaftlichen Studie festgestellt wurde, dass C. nattereri in Wirklichkeit die Art ist, die man bislang als C. nigrofasciata kannte und die „C. nattereri“ aus dem Orinoko und dem...

Or something very closely related.

Exactly, that one.
Yeah! Meinkeni, would be my guess aswell.
I just couldn’t find any reports of it being collected in the tapajos.

Type locality, catch locality and overall range do not have to overlap. Often you know the first and second, but the third is unclear.

Wise words and thanks for the help.

According to this paper on Copella taxonomy, C. Meinkeni is a junior synonym of C. Nattereri, which does occur in the mouth of the Tapajós.

I also have some Copella that I am not sure about…

Arghh!!!
The “Copella-naming-struggle” continues.
I have just found this paper that states that Copella nattereri can be found in mouth of Rio tapajos.
So, the question is.. is that the old or new name for nattereri? I have seen both callolepis and meinkeni named as nattereri (-judging from the pictures).

My understanding of nattereri is: Black middle band with one or two lines of red dots. -correct?

Here is the link to the paper.

Last question… is this c. Meinkeni? (-disclaimer: I have no reason, what it shouldn’t be what they say, it’s just because I’m cinfused)

Yes, meinkeni is a Junior synonym of nattereri. I posted about this last night and linked the paper, but moderators are still looking at the post apparently so can’t be seen yet.

Ohh! So this could be the one I’m looking for..?

Looking forward to read that post.

Well that post hasn't appeared, I am not sure if I am allowed to attach the papers but will try, one I think is the one you have already seen; the other (earlier) describes C. nattered, and the supplementary material one lists two species from the lower Tapajos, natterreri and callolepis.

 

[Mazan]

One didn't upload for some reason...I had these papers in my computer as a few years ago I was trying to id my Copellas...if time I will look for any newer ones.

For what it's worth the link to Glaser contains the clarification. Just switch the site to english.
