Well, everyone was waiting for it. The revision of the "Convict" group of cichlids has been published, and boy, are there some big changes.

First, the "regular" type convict is in yet another new genus, it is now Amatitlania nigrofasciata. (Sounds obscene to me.) There are also three newly described species in this new genus. I don't know yet which one is attached to the HRP - if any.

The next big change is the good ole Jack Dempsey. As many already knew, it was moved to Archocentrus some time ago, but never really fit there. Well, now it has a new genus, and two new sister species. The new name is Rocio octofasciata. Personally, I think it sounds like an Italian pasta dish.

Neetroplus nematopus has been moved to Hypsophrys with the Nic, while Neetroplus panamense has been moved to Cryptoheros, albeit under a seperate subgenus. Also, Herotilapia has been synonymized with Archocentrus, making the Rainbow Cichlid Archocentrus multispinosus. This one is highly questionable under genetic analysis, but the similarity of form has long been noted.

I am awaiting the opinions of real ichthyologists to see if any of these hold. Normally, however, once the paper is published, the names are official until further revision is also published.

Always good to know what information is circulating. How soon can we consider it the rule?
I may have records to update, I consider information such as this crucial and appreciate the time you spent sharing it.

Here's the info about it. I was reading the abstract last night and considering how all this fit into Heijns's "Death of a Genus" article...It just added another couple of Genera...

There is a .pdf of the actual paper out there if any one wants it PM me.

...and I don't believe HRP got treated in this paper...

I found this table helpful (for those who've been following the collapse of Cichlasoma since Kullander's revision)

I'll have more comments once I've finished it and digested...

Oooohhh....It includes a cladistic Key of the new genera as well as related genera (including Parachromis). And not all the physical attributes include things that require dissection of the specimen... :rolleyes: Spine/Ray counts, fin shape etc are included...

(in other words, this work may help when trying to ID an unknown specimen suspected to be "Ex-Cichlasoma")

Correct...This makes Juan's comment about there possibly being 600+ "Ex-Cichlasoma" species descriptions about to hit press kinda scary...

I think we are in for taxonomic cluster&*%& as the race to be the 1st to publish has really begun...The gap created by Sven Kullander restricting Cichlasoma (by designating a type speciesbimaculatum ) to 12 or so actual species is about to implode spectacularly:pop:

It's this kinda thing that causes my adolescent A.D.D. to relapse. :snow:
I'm very interested but all the words just..... :e: .....run together or something.
I get a small fraction of it commited to memory - and it changes :faint:
