Acanthoscurria "brocklehursti"

[dmac]

So I read through some old posts here in the forums related to this, the most recent I think from early last year, but I'm curious if there's any more recent information about the tarantula sold in the hobby as Acanthoscurria brocklehursti. I know of that paper making the original A. brocklehursti a junior synonym of A. theraphosoides, but I still see spiders for sale as A. brocklehursti, rather than as A. geniculata. Is this just out of habit, to distinguish the thinner-banded form from the thicker-banded geniculata, or have there been more changes to the taxonomy?

Some sellers aren't up to date on taxonomic revisions. Others are too lazy to update their inventory lists. Still others cling to outdated names out of stubbornness.

They should be labeled as Acanthoscurria theraphosoides (formerly Acanthoscurria brocklehursti), not Acanthoscurria geniculata, which is a different species.

Here is a link to the list of Acanthoscurria species (currently 28, most of which are not in the hobby yet).

Do you mean that the spiders in the hobby sold as A. brocklehursti should be labeled A. theraphosoides? I thought the hobby spiders were determined to just be a regional variant of A. geniculata with thinner bands? That's why I'm wondering why there are still spiders labeled "brocklehursti" for sale, if it was just dealers not up to date, or if more taxonomic changes were made.

Pet trade A. brocklehursti is a variant of A. geniculata! They should not be labeled A. theraphosoides which is a completely different spider.

See the following article for a key to the Amazonian species of Acanthoscurria. This paper details the characters you can use to key out the pet trade A. brocklehursti to A. geniculata.

Thank you! That's what I was guessing, just wasn't sure if something had changed since I couldn't more recent information anywhere other than the older posts on here.

I am glad someone asked the question, as I was told on another forum that my A. geniculata may not be an A. geniculata at all and this thread helped.

Yeah, I have a sling (freebie) coming in next week and while it's labeled brocklehursti, I intend to label it geniculata, as it should be.

A.theraphosoides is another distinctive species, you can see images of a female here. Quite different looking then geniculata and brocklehursti. http://tarantulacanada.ca/pic.php?active=price&p=A-ferina

Damn you, pet trade labels!

If there is a difference in physical appearance (I'm thinking wide bands vs thin bands) between what used to be called A. geniculata and what used to be called A. brocklehursti would it be be appropriate or acceptable to label them as A. geniculata (thin band variant) perhaps to distinguish the two varieties. I am looking to get some for resale and although the vendor has them listed as A. geniculata (brocklehursti form) I do not want to use brocklehursti at all even if it is just to distinguish between two variants.

Sure, it's appropriate. After the species name, you can put whatever you like between the double quotes or parentheses. Acanthoscurria geniculata "thin bands", Acanthoscurria geniculata "boys hate vertical leg stripes", and so on. It doesn't matter.
