Thanks, this is a first step!

Thamnodynastes paraguanae doesn't seem to occur in Pantanal...

I've find occurencies of the 4 following species, but I am not able to ID which one of the four it could be...
- Thamnodynastes chaquensis
- Thamnodynastes strigatus
- Thamnodynastes hypoconia
- Thamnodynastes lanei

Does it help?
