How about

This is the species that Walsh (1990) lists as Ageneiosus n. sp. and for which some of the pictures in the Cat-eLog exist under . I am not sure if this species was ever formally named.

I was asleep, dreaming of the Tetranematichthys at Pier's

.
Besides, I'm wasn't really needed as 2 members gave a correct ID.
Hammerhead catfish.....makes you wonder how they would call Pangasius spp.
Asian hammerheads??

@HH: what makes you doubt that this isn't the real A. vittatus?

What I've found is that Walsh's name is mentioned in the Checklist of Catfishes (Ferraris) under A. vittatus with regard to the distribution of that species (page 70; last entry of Ageneiosus).

(Sorry, I'm not able to copy/paste that part).

marc - i mentioned in a different thread, that i was at Pier a day too early

I could've got some good photos or even maybe been tempted...... but alas it was not meant to be.

In Walsh's revision of Ageneiosus, Ageneiosus n. sp. is distinguished from A. vittatus by color pattern, differences in number of ribs, vertebrae, branched pectoral fin rays, and head and body shape. The distribution as listed in Ferraris (2007) is for the real A. vittatus as treated in Walsh (1990).
So it seems that this fish remains unnamed.

Do you by any chance have a PDF of this paper?

My tanks are inhabited by more and more undescribed species

Yes, I noticed. That's really too bad.
Let's hope Neil has mercy on us and posts some nice pix himself.

Richard B · Post by **Richard B** » 08 Dec 2007, 15:15

yes indeed, that would be good

I ordered this dissertation and it arrived today. 370 pages! I've got some reading to do

Expect a review - within a year or so.
Thanks to HH for providing the necessary ordering details.

I don't think anybody writes a review for a dissertation. A dissertation is an academic exercise (and not meant to be published like a book), very much like a scientific paper. Nobody writes a review for a scientific paper.

In that case I will certainly not be the first one. Thanks for pointing that out.

Btw: I have to wait until tomorrow to have a peek. The "book" was unbound, so the first thing I did was to make a real book of it by means of synthetic resin adhesive. It was dry within 30 minutes, but I was advised to let it be for at least 12 hours. That's going to be a surprise tomorrow.
