Euathlus and Paraphysa Revision with Phrixotrichus resurrection

[advan]

"The Andean tarantulas Euathlus Ausserer, 1875, Paraphysa Simon, 1892 and Phrixotrichus Simon, 1889 (Araneae: Theraphosidae): phylogenetic analysis, genera redefinition and new species descriptions" (Carlos Perafána* & Fernando Pérez-Milesa 2014)

Abstract:
"Based on a phylogenetic analysis we revised the Chilean tarantula genera Euathlus and Paraphysa. As results of our analyses, within a wider context of South American lineages, Paraphysa is synonymous of Euathlus, and Phrixotrichus is resurrected. Euathlus and Phrixotrichus are sister genera, supported by their shared palpal organ morphology, especially at the ventral position of the distal prolateral inferior keel, also by spermathecal receptacles with a lateral chamber, and tarsal claws without teeth. Both genera are redefined based on cladistic results, and some of their constituent species are transferred. We describe four new species, and for the first time present the spermathecae of Euathlus parvulus comb. nov. All species described for both genera are diagnosed and keyed. Euathlus now includes: Euathlus antai Perafán and Pérez-Miles sp. nov., Euathlus atacama Perafán and Pérez-Miles sp. nov., Euathlus condorito Perafán and Pérez-Miles sp. nov., Euathlus manicata (Simon 1892) comb. nov., Euathlus parvulus (Pocock, 1903) comb. nov. and Euathlus truculentus L. Koch, 1875. Phrixotrichus now comprises: Phrixotrichus jara Perafán and Pérez-Miles sp. nov., Phrixotrichus scrofa (Molina, 1788) comb. nov. and Phrixotrichus vulpinus (Karsch, 1880) comb. nov. Furthermore, Paraphysa riparia Schmidt and Bolle, 2008 is synonymized with Eupalaestrus weijenberghi (Thorell, 1894), Paraphysa pulcherrimaklaasi Schmidt, 1991 is transferred to Maraca Pérez-Miles, 2006 and Paraphysa peruviana Schmidt, 2007 is considered a nomen dubium."

Bummer about the paywall. I can't get access through my university yet but I'll have to remember to check again in a month or two. This looks worth the wait.

 

[Beary Strange]

I was hoping maybe sp.red/yellow might finally have a proper species name and unless I'm reading this wrong this doesn't seem to be the case.

 

[Storm76]

Darn it - 34 EUR only to freaking view the document? Wow! Thanks for the info, Chad! Can't wait to get my eyes on that paper!

:coffee:

Paraphysa pulcherrimaklaasi Schmidt, 1991 is transferred to Maraca Pérez-Miles <<< guess I have to rename some T's here

Me too. I got the same from it. Oh well, in time I guess.

Dr. Longhorn has hinted at those possibly being Homoeommo species.

Maraca pulcherrimaklassi has never been in the hobby to my knowledge. It's best to label them as Euathlus sp. 'blue femur' until further notice.

True, I had a long PM / EMail conversation with him about exactly that. If I remember correctly (I would have to look it up) the currrent Homoeomma sp. "blue" are probably Euathlus spp. according to him. But again - don't quote me on the last part I'll have to check my mails...

Well, that's what I have on their cages aside the pulcherrimaklaasi. Schmidt was always somewhat not thorough from what I read...I'll keep them as they are for now then.

Gotta get a message to Stuart and ask him about this again..

 

[Smaughunter]

So Paraphysa scrofa is now Phrixotricus scrofa, I got that one. And Paraphysa parvula is now Euathlus parvulus? I've got to change some labels.

 

[LordWaffle]

Pretty big change. I have many of these species. It will take some getting used to.

As far as the possibility of Euathlus red and yellow being from Homoeomma, I can see some pedipalp and other mouth part similarities between my Euathlus yellow and my Homeomma blue (which could be coincidental as I've heard rumors Homoeomma blue my be placed in Thrixopelma)

Careful! Don't bring up that subject: There are two different species (spermathecae is looking different on them for example!) Thrixopelma lagunas & Homoeomma sp. "blue" - for example the user fraxinus on here is still working on the whole thing, too. Bottom line: There are differences between these and they are not the same species.

 

[LordWaffle]

I'm aware that they're not the same species. Ok collecting as many Homoeomma sp blue as I can because I want to start breeding them. That's also why I was saying it was rumored.

Moving on, you can see strong similarities
Between the pedipalp and mouthpart structures on euathlus red and yellow and Homeomma sp
Blue.

This is true I believe. I talked to a guy on the board here before I bought the E. sp Yellow/Red. I was searching for info on their habitat because no one had any to my knowledge. Anyway, someone replied back and told me the same info regarding Homoeommo and these unclassified E sp Red/Yellows.

Hi! I know this is an oldish thread, I hope some can help answer my question. I bought my first t, labelled in the shop as Euthalis sp blue. Since I am new to the hobby I am having some difficulty understanding the classification.

My first question: Is Euthalis sp blue the same as Euathlus pulcherrimaklaasi and/or Pichidangui Blue Beauty?

Second: What is the difference between Homoeomma sp. Blue and Euthalis sp Blue? I am trying to figure out which one of the two my T is.

Thanks so much!

a) Yes.

b) Below pictures should speak for themself:

E. sp. "blue" ("pulcherrimaklaasi")

Homoeomma sp. "blue"

Despite the obvious differences of grown T's (both pics above are females at sizes of 4-4.5"), as sling they're mostly brownish without any coloration, kinda looking like G. rosea even at that stage.

 

[Zeek]

Thanks so much, looks like mine is a e. Sp. Blue! She just had her first molt a few days ago and looking forward to seeing her colours Thanks once again

Bumping this old thread instead of starting a new one.
I'm about to receive a (new to me) dwarf Chilean T and cant find anything definitive regarding
which species it is currently described as so I can label it (for now)
Euathlus or Phrixotrichus, any help would be much appreciated.
currently sold to me as Paraphysa sp Chilean Bronze , but I did find that it has recently been sold as
Paraphysa sp north or sp tiger. Further searching seems to show that sp tiger is a completely diff T.
So is it going to be E. sp north or P. sp north?

[Ultum4Spiderz]

Cool ! good correction , I wonder when N cromatus will find its true genus.:biggrin::biggrin: It does not resemble my other nhandu by much.

 

[gcandd]

link picture looks like a dwarf rose hair, nice looking tarantula whatever it turns out to be.

 

[cold blood]

could be scrofa.

 

[sdsnybny]

could be scrofa.

Not sure but it looks like the picture in the link shows the stripey abdomen of some of the Euathlus T's, didn't think Phrixotrichus scrofa had that characteristic?
Google search shows a different looking T for Chilean Bronze than P. scrofa but close.
