Two new Doumea

[Silurus]

Ferraris, CJ Jr, P Skelton & RP Vari, 2010. Species of the Doumea chappuisi complex (Siluriformes, Amphiliidae) with the descriptions of new species from the upper Sanaga River and Nyong river basins. Copeia 2010: 705–715.

Abstract

The Doumea chappuisi complex within the catfish family Amphiliidae is diagnosed on the form of the dorsolateral and ventrolateral processes of the vertebrae along the posterior portion of the body. Three species are recognized in the complex: Doumea chappuisi of the West African coastal river basins in Guinea, Guinea-Bissau, Cote d’Ivoire, and Liberia; D. reidi, new species, described herein from a portion of the upper Sanaga River in Nigeria; and D. stilicauda, new species, described herein from the Nyong River basin in Cameroon. Members of the complex are distinguished from each other on the basis of the overall body form, the caudal-peduncle length, the predorsal length, the head length, the degree of development of the pelvic fin in larger specimens, the anterior extent of the exposed vertebral processes along the ventral surface of the body, and details of the pigmentation pattern of the unbranched rays of the pectoral and pelvic fins.

Is anything further available? (to purchase or as a pdf?)

Richard , if you mean this paper it is on its way.

Anyone else wondering why there isn't as much clamour about this description versus the new Panaque? In reaction, I wonder if someone would like to work at adding these two species and getting some more data in for the genus?

Just a thought.

I can certainly have a look at the information, can't add the species though!

If someone tells me what species names (in Bugs & Suggestions, perhaps), I can add those.

I guess we African enthusiasts just are not as excitable as the South American pleco enthusiasts but with all the excitement the Cat-elog is going through, and there has been a lot recently, I had just plopped it on my list of things to look at.

Really though for most these are an obscure little fish most will never see but honestly I would have thought the Auchenoglanis revision would have gotten more attention, that one is on par with the Panaque revision.

There are two brand new species to science but three new to the Cat-eLog, all have been added.
