Looks like this:

Not from Peru though.

Because of the large and visible barbels, I'm leaning more towards Pseudeutropius brachypopterus. It sits in Schilbeidae. Have a look at all pictures.
But again, not from Peru....

I don't think those are Pseudeutropius. I am fairly certain they are some kind of Auchenipterus (which makes their origin from Peru more plausible).

- that's a REAL find. Any chance I can have some pics?

The crazy zigzag near the lateral line is the giveaway...

Is the "wavy" lateral line unique for Epapterus dispilurus?

These photos have earlier been posted on a Swedish website, and a coworker of mine, who's far better at catfish than me, thought it might be an Auchenipterus nuchalis (although his first impression was "some Epapterus").

Both Auchenipterus and Epapterus have this form of lateral line, although this is also not unique to auchenipterids.

Now that I've been put in the right direction (Auchenipteridae; how about that

), I have a certain ID on the genus, but not on the species.
Epapterus have always reminded me of glass catfish in appearance, especially because they have a small dorsal close to the head and lack an adipose.
So the fish in the picture must be Auchenipterus (larger dorsal and an adipose). But which one?
No problem, there is only one species. At least in 1974...
Now there are 11 valid species, of which 9 are not native to Peru, including A. nuchalis, the best known fish of the genus and - until 15 minutes ago - my best bet as well. There are two that are: A. ambyiacus Fowler, 1915 and A. brachyurus (Cope, 1878). I have never seen pictures of these two, but I surely hope they look a lot like A. nuchalis, for this one looks identical to the fish on Altifrons' pictures.
BTW: I checked several books for descriptions of these fish. They state all the same. Unfortunately Burgess has swapped the captions, thus making it look like Epapterus is Auchenipterus and vice versa ( pages 590-595-596; Atlas of freshwater and marine catfishes ).

Using the Ferraris & Vari (1999) revision of Auchenipterus (I know Marc may want to get his hands on a copy), it looks more likely to be A. ambyiacus.

Are you telling me you have a spare one?

Or have you perhaps found other ways to obtain a copy?
If so, I'm very interested indeed.

Wow, it's completely filled! Very impressive. Thank you so much

To HH: the printer has been running for more than one hour, but I now have all 64 pages in my hands. Reading time

To Jools (if you're going to add this species to the Cat-eLog): Auchenipterus ambyiacus Fowler, 1915. This species has NO synonyms.

Altifrons, did your LFS have a name for these catfishes? It may not have been on the tank they were in, but there should have been a name on the orderform from the wholesaler. Is this much trouble for you to find out?
Thanks.

Altifrons · Post by **Altifrons** » 09 Mar 2006, 18:27

They didnt have any information,the catfishs came by mistake in a box with pim-cats.

Post by **Marc van Arc** » 09 Mar 2006, 20:13

Goodness, I wish they made mistakes like that around here as well

.
Anyway, thanks for your reply and take good care of your very special Auchenipterids.

Mistakes happens everywhere but you have to be in the right place at the right time
