Grammostola rosea vs porteri

[david clarke]

Hi all,

Just a quick question. Does anyone have any information on rosea Vs porteri? What is correct?

Thanks
David

According to The World Spider Catalog, Version 12.5 (Platnick) G porteri and G rosea are two different species.

As far as i'm aware G porteri is NCF (normal colour form) and G rosea is RCF (red colour form)

Hi Peter

Thanks for the reply. I've seen NCF refered to as porteri. I hadn't checked The World Spider Catalog, so good to know. If you come across any other info, please give me a shout....

Thanks
David

What do you need/want to know ?

Hi Peter,

The more I try to look into this, the more confusing it gets. I understand that The World Spider Catalog lists them as two different species, however, I can't find anything that tells me porteri is, rosea NCF. Is there any info that relates specifically to this? Some of the info I've been looking at suggests that traders changed the species name, to differentiate between their sales.

Cheers
David

This topic also interests me, Id also like to read the paper where Grammostola rosea NCF is synonymised with Grammostola porteri, has anyone got a copy?

[Ray Gabriel]

I knew of a couple of traders in the distant past who would sell freshley moulted specimens as cala and the others as spatulata, before they became synonymous.

As far as I know the rosea type is missing, and not sure about the porteri type, but many of Mello-Leitao's types are also missing, until a revision of the genus is done who knows?

But good to keep the colour forms apart.

Good day folks,

this question is a good question. I only know...in the past most of these spiders were sold as G. rosea because of the red colour and the other colour-types (brown, grey, silver...) as G. porteri. Ray Gabriel described it very good. At this time...we have to wait until a revision.

Re: Grammostola rosea vs porteri

I was told once that porteri was bigger and calmer then the rosea.
I got a female porteri from a German seller at a SEAS show and she is so relaxed .. She is a grey/brown and nothing like the rosea I've seen.

Bottom line, don't re-label anything? Just differentiate the colour forms? And await the revision.....
