I am interested in these two.

ChocoEgg 1 Japanese Luehdorfia butterfly
ChocoEgg 3 great purple emperor butterfly

Do you already have the green-cheeked Amazon by Safari? https://store.safariltd.com/products/wings-of-the-world-birds-green-cheeked-amazon-parrot-figurines-263729

Thank you all! Yeah, that is a great set, I didn't know it!! It's on my wishlist now haha

The Alouatta is probably A. caraya, which makes my diorama wrong, because A. caraya does not live in the Amazon lol gonna need take new pics.

I'm really new to this, any websites I can look for it regarding japanese brands? I've checked Collecta, Safari, Papo and Schleich, I don't know other ones lol

Thank you again! xx

Here you can buy the whole set: http://buyee.jp/item/yahoo/shopping/yuyou_g150553s01?lang=chs for 14 US dollars, This is not including the gray hercules I think. When these set arent sold by shops anymore, the prices go up very much because the single figurines and whole sets are considerd collectors items.
Buyee is a forwarding service I have used for 7 years, I can recomend them when buying from Japan.

How Buyee works
You will have to make a Buyee account. Their website is in English as well. It is handy if you have a PayPal account.
They will buy your item and charge you a fee. They will do the purchase and let you know when the items arrive at their wearhouse. Then you choose a shipping option and make payment for the domestic shipping (seller to Buyee) and international shipping (Buyee to your house)

Special requests: Armadillos, Coatis, Spider and capuchin monkey, tamarins, Rhea, Amazonian River dolphin, Green parrots (not macaws), Giant River otter, peccary.

For Spider Monkeys, there is the Safari Ltd Spider Monkey, which is good but a bit generic.

For Tamarins, this year Papo is releasing a Golden Lion Tamarin. There is also a Safari Ltd Golden Lion Tamarin, but I think it is discontinued, so be prepared to dish out a lot on it.

The Safari Ltd version is also out of scale with many of the figures in your display, if that matters to you.

For Peccaries, I would definitely recommend the Safari Ltd Peccary. It is pretty clearly a Collared Peccary (which is, to my knowledge, a fairly widespread species in Brazil), and it is adequately small for your diorama.

I don't know of any figures (that are easily avaliable) of Armadillos (), Coatis, Capuchins, Rheas, Amazonian River Dolphins, Green non-macaw parrots (Safari does make one, but it isn't based on a Brazilian species) or Giant River Otters, but I do wish many of these were made.
