I am extreeeemely color blind.
edit: Thanks for clearing that up! What do you mean - between those two? Would you be able to foster a guess otherwise? Any insight is helpful, I appreciate you taking the time
@Philosopheliac There has recently been somewhat of a ban on the Chilean t's. From what I can discern, G. porteri imports have slowed if not stopped. Now what is going under "Rose Hair" in those pet stores are actually Grammastola sp. "Northern Gold" (an undescribed species). I'm not the best at ID'ing these especially just by one pic (my eyes aren't the greatest), so I'll get a few links to the subject when I find them.
The difference between porteri and rosea IS NOT COLOR. Breeders have reported that get all color forms from a single sac of G. rosea.
IF ROSEA WAS THE "RED COLOR FORM" THAN YOU WOULDN'T HAVE TWO DIFFERENT SPECIES NAMES!
Allegedly, G. rosea and G. porteri grey form are different species. And, allegedly, you have to inspect the lyra on the underside of the legs in comparison across specimens.
@comradewho I've heard of reports of the RCF and NCF coming from the same sac but I've not heard confirmation. Not sure though, I could be wrong. Perhaps I worded incorrectly, lots of hobbyists refer to the NCF as being G. porteri and the RCF of G. rosea, though I believe we don't have definitive proof. @Exoskeleton Invertebrates may help shed some light.
Yeah I know that's a hobby practice @BobBarley and I know there's dispute, and this is one of those areas where there is just a lot of confusion. What does make more sense to me is that the mistake is made because of the similarity of the NCF G. rosea and the G. porteri, the fact that importers and sellers are generally not going to be able to distinguish since the alleged scientific distinction requires a trained eye, and that the two species have been confused though it's also possible the same factors of sloppiness led to G. porteris being inappropriately labeled G. rosea and the emergence of the "RCF" label as an unscientific but still accurate way to create the distinction. IMHO Grammastolas in general look extremely similar to each other and is a genus that really shows why visual ID is so frought, and I am inclined to accept the explanation that there are two nearly identical Grammastola sp. Look at G. conception for example - while not identical they appear very similar to G. rosea RCF.
Also consider that "Rose Hairs" with both dominant brown or grey coloration are often commonly labeled as either G. rosea NCF or G. porteri, even though this is a visual distinction and other hobbysts and sellers recognize three different spiders. So even if you accept that G. porteri is the "normal form" which is the normal form, are both the brown and grey color forms the normal form / porteri and G. rosea is just the RCF? Or, is G. porteri only one or the other between the grey and brown and if so, which one, and what do you label the other two G. rosea?
