Heptapteridae in Cat-eLog

[Suckermouth]

Hey, is it just me or does Heptapteridae in the Cat-eLog not go to the right page? I'm getting a page that just has two species on it.

[MatsP]

Yes, it appears indeed to be broken.

I will have a look at it tomorrow.

Mmmm, it's a problem becuase there is a genus called Heptapteridae too (for unidentified beyonf family species).

Jools

[Acanthicus]

I´d just call that group "unidentified (members of) Heptapteridae".

[Marc van Arc]

Mmmm, it's a problem becuase there is a genus called Heptapteridae too (for unidentified beyonf family species).

Could they be named Heptapterinae (sp1, sp2 etc) as in Auchenipterinae? Or would that scientifically be incorrect?

I like that idea if it's correct!

[Silurus]

Unfortunately, it's not. The easiest solution would be to try and assign genera wherever possible and get rid of unidentified genera.

[Jools]

Just as so I understand, is that because there are no defined subfamilies in

Heptapteridae

?

Jools

[Acanthicus]

Heptapterinae would be a non valid subfamily and would only lead to confusion.

[Silurus]

AFAIK, there has been little work on the infrafamilial relationships within the Heptapteridae, so there isn't a decent hypothesis of relationships that would allow us to define subfamilies.

[Jools]

OK, so, how would one label (in text) a Heptapterid that doesn't sit well in (or has not been identified to) a genus as far as we can tell?

Jools

[Silurus]

I would use “hepapterid” instead of Heptapteridae. But let me try to identify the two (although this is not a long-term solution). I believe sp. (1) is a juvenile Megalonema xanthum (It might also be a Cheirocerus, but these typically have a dark bar over the base of the dorsal spine which the fish lacks). I'm still working on sp. (2).

[Silurus]

Sp. (2) looks like the fish identified as Rhamdella cf. leptosoma by Le Bail et al., (2000), so I'd refer it to this genus for now.

Ideal, I'll do that.

I believe sp. (1) is a juvenile Megalonema xanthum (It might also be a Cheirocerus, but these typically have a dark bar over the base of the dorsal spine which the fish lacks).

Maybe the Cheirocerus is the better option. I think I've kept this species and it doesn't grow move than 8cm. Is, also the adipose fin not a bit off too? Some of Mark's photos are very "fresh" imports and so it (the dark bar) could be a bit washed out.

BTW, I gave these fish to Adrian, so maybe he could take/post a few pics too?

Yes, it does initially, but look at the "bare back" distances from the dorsal to the anterior start of the adipose and the same between adipose and caudal. Also the eye size and snout look a bit off and are the reason I didn't put it in

Pimelodella

. Small differences, but I find so many of the Heptapteridae genera as such.

Jools

[MatsP]

Did you (Silurus and/or Jools) actually mean for it to be Hepapterid rather than Heptapterid for these unidentified species?

[Jools]

Minor typo from HH and I missed it too when copying and pasting. The p should be inserted (as opposed to taken ).

Jools

[MatsP]

Sorry, do you mean p or t?

--
Mats

[Jools]

Sorry, in-joke with myself - in retrospect, not very clever.

Insert the t, not take the p.

Jools

[MatsP]

I will fix.

Edit: No I won't - there is no way to do that with the functionality I can use...

Mats

[Jools]

Fixed the typo.

Jools

[Jools]

OK, so there is a problem with this

Hemibagrus

(e.g. planetcatfish.com/<genus name>) type of link due to the last fix/change. A placemarker so I can have a look at it at a better time.

Jools

[MatsP]

Moved this to "Bugs" section based on the fact that it leads to "incorrect behaviour", rather than "the data itself is wrong" (which belongs in the Cat-eLog section).

Since "genus rename" doesn't exist, I can't fix this myself - Jools needs to "poke" the database (or I we need a new function in the admin pages).

Mats,

I've just read the post from top to bottom and I don't understand what the bug is. Can you explain what your understanding of it is?

Cheers,

Jools

[MatsP]

I thought there was a problem with Hemibagrus, but looking at it again, I think it's fixed, so will move to resolved! [Another one bites the dust! ;) ]
