New Neotropical Cichlid Phylogeny

(If I'm pessimestic and note about it on this board, I have a history of success!!)

Hopefully I did not screw this up. I had to save the eggs since the other uros were penetrating the pair's defense, along with a group of Paretroplus maculatus and a spare menarambo that seem to be creating much confusion for the pair with their schooling behavior.  And then to make it more complicated, this tank is squeezed under a the lower level of a double stand this is far too short and I can only get my arm within the tank about 6-8 inches.  So I netted the slate with the adhered eggs and dropped them in a 10g with meth blue. They were exposed out of water for 5 seconds - let's see what happens.

Awesome Scott, thanks. You can just give them to my dad at a meeting or something and he'll get them to me.

I have a confession. I'm a cichlaholic.

Mr. Nuth was right.  Sam, you should be getting some uro fry for your studies. Let me know if I need to ship the vials out west.

Let's keep our fingers crossed.  Mr. Nuth88 stopped by tonight and had some great ideas to put the uro's in a position to breed. I followed his instructions and now they are on the clock.  Now doing my raindance.

That would be awesome. I've got some ethanol for you I'll bring to the next meeting. I've got a nice wild pair of Urophthalmus "moskito coast" and they are stunning fish. They bred once, but the eggs weren't fertile. Very cool fish.

Thanks.  Maybe if things work out, I can get fry for both splendida and urophthalmus for you.  I have a group of six urophthalmus where one female is displaying.

No. It's thought that 'Urophthalmus' most likely has a relation with Petenia. This seems possibly as juveniles of both species look very similar, although I haven't looked at newly free swimming species of either fish. Although they are probably not going to find themselves in a genus together, there is probably a close relationship.

Sam - did urophthalmus get moved to the Amphilophus genus?  I see Rapps has them id'd as such on his photo gallery, but I could not otherwise find any reference other than xCichlasoma.

Some interesting parts of Central American phylogeny that is still up in the air is the status of the Archocentus/Cryptoheros/Amatitlania group of fishes. What is also interesting (and something I'm not sure I agree with) is the authors suggestion that Australoheros are closey related to this group.

It's also interesting to me that they place Herotilapia closely with Tomocichla. I see no way how this is possible. The don't have A. spinosissimus in the tree, but it would be interesting to see where it falls. They do place A. centrarchus in close relationship with Amphilophus. This relationship has been suggested before.

It's peculiar that the authors don't use Vieja or Paratheraps and use Paraneetroplus for many of the species grouped in those two genera. Also the designation of Theraps is interesting and where some of these species fit in.

It is interesting to see where the Jack Dempsey Fits in also, here it is listed as an Astatheros. It still shows how enigmatic this fish has been for proper taxonomic placement.

A relationship between Petenia and 'C.' urophthalmus is also show pbulished in this paper and I think it is highly likely these fish do share an evolutionary past. This has also been proposed before.

The paper also finds Australoheros, Caquetia, and the festae group to be closely related to C. American cichlids even though they are S. American. No surprise here though.

For S. Americans. The placement of Acaricthys is intriguing.The use of Teleocichla is also surprising in this study.

That's brief, but it's a lot of fish they cover. This is DNA only!  It's surprising a study with a very large sampling size with both  a morphological and DNA analysis  hasn't been done recently.

I going to have to print it to read....

Sam can you give us an abridged version?
