G. pulchra x G. quirogai Side-by-Side Comparison - Photos and Videos

[OldFlash]

I forgot to ask in my previous post. Are the two pictured wild collected individuals, or direct descendants, from Brazil? Or the G. quirogai from Uruguay and G. pulchra from Brazil?

First thing I asked when they got here. He didn't exactly know either, but he believes one pulchra is wild caught, the other one he's trying to get more information. I'd bet some money she's also wild caught. The two quirogai are from his own collection, got them as slings and as quirogai.
One thing I can safely say is that 3 days are more than enough to confirm they do NOT have the same temperament at all. I mean, not. at. all.

this is amazing. I really love all this information you are sharing with us. Its so relevant.

theres not many dealers in canada. Only one of them lists BOTH: pulchra and quirogai. And i always found that so odd.

now i think i will have to write to them. They carry wild caught as well.

anyways, i find this very informational, and id definitely put helpful/informative at many posts, but i cant because of my phone upgrade.

Do you have pictures of the spermatheca?

I like that you find it relevant. Thank you, I really appreciate it

I don't.

I don't.

Without photos of spermatheca or direct lineage information, I wouldn’t consider this conclusive. Who’s to say they aren’t all hybrids or intergrades, or different phenotypes, maturities, or in different points in the molt cycle? Interesting topic and worth documenting, but this isn’t the end all be all. Just my opinion

Got intrigued by this post and was curious to look at actual genetic similarity between these two specimens. Utilizing the BLAST (Basic Local Alignment Search Tool) to compare protein sequences. I compared specifically the protein Cytochrome c oxidase subunit 1 which is a protein found in the mitochondrial membrane of both Grammastola species and plays an integral role in oxidative phosphorylation. However, interestingly enough the protein makeup for these proteins are virtually identical in both species; which suggests a very recent split in lineage.


I tried to compare another set of proteins but all I could find for both species on the database were coding sequences for the aforementioned Cytochrome protein.

These very similar specimens in morphology does get my mind thinking a little..

The spermathecae is uniform across all species of Grammostola, with the exception of two species, and not useful for delimiting or identifying species. It is more of a generic character.
