Re: Pseudacanthicus major, new species (Loricariidae)
I'd be more confident assigning to the photos currently in .
For me that "histrix" fish has an appearance more consistent with P. major: the smaller, higher and triangular shark-like dorsal fin (with filaments), and the small eyes, i.e. also and .
The fishes in P. major look more like .
I don't have my books handy so I don't remember what the original DATZ L186 looks like.

Re: Pseudacanthicus major, new species (Loricariidae)
L064 should be combined with L186 but BEFORE we do that, we need to know where to put the pictures in that are currently in L186. @Acanthicus, could you look at here on Planet - I get the feeling a few of the pictures are ?

Re: Pseudacanthicus major, new species (Loricariidae)
@Racoll, I also agree that all images currently in P. histrix should be moved to P. major and have moved them.

Re: Pseudacanthicus major, new species (Loricariidae)
Hi Jools,
agree, the following ones need to be removed from P. major:
https://www.planetcatfish.com/common/im ... e_id=14974
https://www.planetcatfish.com/common/im ... e_id=14975
https://www.planetcatfish.com/common/im ... ge_id=4629
https://www.planetcatfish.com/common/im ... ge_id=3591
https://www.planetcatfish.com/common/im ... e_id=19940
https://www.planetcatfish.com/common/im ... e_id=19941
- Wasn't this specimen from the Belo Monte area?
It's coloured different to all we know, but I wouldn't leave it here either and move it to P. histrix. P. major is "lacking spots or blotches".
I am having a little issue with the distinction to P. histrix, colouration doesn't seem a trustable characteristic to me. The only chance to be sure about the ID of a living specimen is a dorsal view of the head if I understood the paper corectly.
cheers, Daniel

Re: Pseudacanthicus major, new species (Loricariidae)
It's a bit confusing. The diagnosis lists a whole load of osteological characters that distinguish major from all others (including histrix), but then the paragraph on histrix says nothing about osteology, just colour pattern. They only examined a single 7 cm example of histrix from the Xingu, and that was labelled cf. histrix. They state the Xingu histrix has no stripes in the caudal and dorsal fins, but the images of fishes online, purportedly from the Xingu all show spots and stripes, including Pseudacanthicus sp. "Belo Monte" in Wels Atlas II.Acanthicus wrote:- Wasn't this specimen from the Belo Monte area?

I would like to see more evidence to discount histrix. On the basis of Capello's illustration, they are almost identical, with the same large pectoral fins, the tiny eyes, the small triangular dorsal fin, and the plate-like procurrent caudal rays dorsally and ventrally to the caudal peduncle. No other Pseudacanthicus has these. It's a very distinctive fish, and P. histrix has been reported all over major rivers of the Amazon and Orinoco basins, so probably has a fair amount of colour variation.

Cool. Would you say move these to ?Acanthicus wrote: ↑06 Mar 2018, 23:02 agree, the following ones need to be removed from P. major:

Having read the paper, I cannot say if is P. histrix or P. major thus expanding the range of the latter. Any views?

*bump* Is L064 = L186? I can't really see any differences?
