Nomenclature changes in two Central American cichlids
By Juan Miguel Artigas Azas

A new paper by Rico Morgenstern brings to light facts that force important nomenclature changes for two well-known Central American cichlid species: Parachromis friedrichsthalii and P. loisellei. The paper details the circumstances and presents an examination of the fish collections made by Emanuel Ritter von Friedrichsthal in Central America between 1838 and 1841. The most important results establish that the fish we now know as Parachromis loisellei was in fact previously described as P. friedrichsthalii, a name we should now use when referring to this species. The fish hitherto known as Parachromis friedrichsthalii should now be called P. multifasciatus. The name Parachromis loisellei falls now in junior synonymy with P. friedrichsthalii. These changes may create confusion but get use closer to have a sounder picture of Central American cichlids taxonomy.
Morgenstern, Rico. 2018. "Fishes collected by Emanuel Ritter von Friedrichsthal in Central America between 1838–1841". Vertebrate Zoology. v. 68(n. 3), pp. 253–267 (crc09154) (abstract)

Interesting, seems the fish we know as P. friedrichsthalii, may have actually had some confusion around it's description and thus the fish we have should actually be P. multifasciatus, not sure if I've seen P. loisellei around in Aus, but apparently that is the true P. friedrichsthalii.
I understand that this might be old news for some, but was news to me, so thought I'd share. haha

My Umbees

Sitting here waiting for the diazepam to kick in before a tooth extraction at the dentist...

Thought I'd share a couple of quick crappy phone pics of my big male Umbee. (a few months old, he's grown and filled out a lot more since these were taken.) Currently have been making some tank changes to get him to interact with the female I have in with him to get some pair bonding happening, which seems like it might be happening now. Got another female waiting in a spare tank just in case.

Fingers crossed I can get some spawning soon. Absolutely spectacular fish that don't get the recognition they deserve. They are big brutes, but also big sooks, they really do have nothing on the aggression of Dovii in my experience, but that certainly doesn't stop a big male going rogue and decimating all other conspecifics in a tank should he so choose. It would really be nice to get some fry of these circulating again.

I hope you enjoy.
Cheers. 1ccab7ec434d91fd43a8c5c2462b2de4.jpg04d802a8620ae30f01b5e3206743f1cc.jpg4e8e890f36333d7483587423afd8e84a.jpg
