Avicularia sp.?

@AracKnight where did you get this information? I'm very interested in Theraphosid taxonomy and I'd love to read up on this.

It is definitely an Avicularia avicularia, the days of "can't ID the species of an adult Avicularia from a pic" is over since the revision in my eyes... None of the other valid species look like this and are distinguishable with adult coloration. It's now a new era that we aren't trying to figure out what species it is, but rather what color form and/or locality it is, which brings us to the same problem when breeding. The OP specimen is a Avicularia avicularia morphotype #6 aka hobby metallica. What you can't tell in a picture is the locality or exact color form so breeding is again a no go. Most pet stores get wild caught specimens from Guyana, according to the revision only Avicularia avicularia morphotype #1 (hobby Avicularia avicularia) & Avicularia avicularia morphotype #6 (hobby metallica) are found there... These two morphotypes are found in northern South America from Venezuela to French Guiana and also in north - northeast Brazil. Depending on locality it can determine the color form as their are slight variations in color within most of the morphotypes. So for example, the metallica (Cayenne) or green are the same species and same morphotype as the hobby metallica we all know from Guyana, they are a slightly different color because they are from French Guiana.

@Richard Stewart BTW slight variations in carapace color is not a characteristic I'd use to determine an ID.
It could still be the same as your other metallica. The carapace color can look different for many reasons other than it's a different locality like size, where they are in their molt cycle, or just individual genetics can be the reason for slight carapace color variations.
It might also look different than your Captive Bred metallica because they are muddy up with other localities through hobby breedings. Too many possibilities, and I heavily assume a lot of CB Avicularia avicularia have been breed with different localities with slight coloration differences. So to my point, figuring out the exact color form or locality is impossible from a pic.

@AracKnight The metallica in the hobby are for the most part all the same species besides the few that are obviously mislabeled, all are Avicularia avicularia. A lot of times hobby Avicularia avicularia (morphotype #1) are sold as hobby metallica (morphotype #6) and vice versa...

Hobby species like Avicularia geroldi, braunshauseni, metallica, velutina, kwitara river and all those look a like localities (that are now considered invalid) from the areas studied in the revision are a color form of Avicularia avicularia. Avicularia avicularia is cut up into morphotypes depending on characteristics of appearance. Avicularia avicularia has 7 different morphotypes and many different color forms and some size variations within most of these morphotypes.

It's a gorgeous looking pink toe though

@CEC None of the other DESCRIBED species looks like this one, that doesn't mean that it's definitely an A. avicularia, it's just most likely. This "it resembles most" was the kind of mindset that actually caused all the confusion with the hobby material.

I agree that geroldi, azuraklaasi, ... are most likely morphotypes of A. avicularia but without examination of our hobby material nobody should actually claim smth. to be "definitely this species", it would most likely start the same problem we had before the revision all over again.

To rule out A. variegata just by this picture is highly questionable since the leg rings are weakly developed in juveniles and can be easily overseen in such a picture. And without considering these leg rings they can look pretty much the same.
Also you have to consider morphotype 5, cause in the hobby hardly anyone knows how this one looks. The picture provided by Fukushima&Bertani only shows a preserved specimen, so coloration faded out. If you look up Table 2 you'll see, that morphotype 5 differs from 6 only by "pale yellow" instead of "whitish" leg rings and "reddish" instead of "brown, gradually lightening" abdomen, guard-setae, color.
Even Fukushima claims the necessity of "employ multiple approaches, considering molecular, ecological, behavioral and geographic data", but we are able to identify an Avicularia sp. just by ONE not even good picture? Dream on.

@MissHarlen you can download the revision here: http://www.wsc.nmbe.ch/reference/13817
(You have to register on thsi site, but it's completely free, not even spam or smth. The registration can take a few hours or even days until it's confirmed, but it is working )

@CEC For now all those "species" like geroldi etc are considered A. avic. However, it will take another revision for all of the nom de plume's to be fully characterized. For now, science says they are A. avic, personally, I'm not sold on that.

It was the opening line of the caption that confuse me most

@AracKnight Our mentality of this one shouldn't be bred is the same. You say you don't know the species but I say I don't know the color form, either way, it shouldn't be bred. People mix these things out of ignorance or have a "I don't care" attitude, not because I explained why not to breed it, they'll do it anyway...

There is many differences between variegata and this specimen. The hobby sp. Amazonica (Manaus) is the only morphotype (#1) of variegata in the US hobby. Look them up to see they have obvious differences throughout their adult coloration. If you need me to point out the many differences just ask and I'll point them out to you.
Now, morphotype #5 is from Bolivia and yes, I agree with what the revision says... Their setae is not as grizzled, have yellowish leg rings but they have reddish abdominal setae, especially fresher from molt. The OP specimen is clearly not reddish. The Bolivian types are extremely rare, if any at all in the US hobby because Bolivian exports are rare. Thousands of Avicularia avicularia are exported out of Guyana, that's where majority of the wild caught come from. Now if you think it could be CB than what other valid species that's in the hobby could it be? Only one, Avicularia avicularia. The only other option is a new species to science, ha... Dream On.
Even if you are correct and it is a morphotype #5. That brings me back to my original point, it's an Avicularia avicularia. Figuring out the locality/color form is the impossible part because the characteristics between them are a lot harder to tell apart than the 12 valid species from the revision.
I understand the confusion of the color description for most, as they are hard to picture if your not as familiar with them. If you have raised many of these morphotypes it's a little easier to put the words to images.
