I live in Rondonia, so I expect the more equatorial Grass-types and most bugs, like Paras, Victreebel, Exeggutor, Tangela, Ariados, Heracross, Treecko, Tropius, Snivy, ect.
There are a lot of plains here as well so Rattata, Kangaskhan, Girafarig, Dunsparce, Donphan, Zangoose, Seviper, Watchog, Blitzle, ect.
Also more tropical, river and jungle-based Pokemon like Zubat, Seaking, Lickitung, Feraligatr, Marill, Umbreon, Shiftry, Slakoth, Exploud, Spoink, Whiscash, Kecleon, Woobat, ect.
Actually in my city there are more cows than people, so Tauros, Miltank and Bouffalant. Also a lot of cows equals a lot of dead cows, so Mandibuzz as well.
Hmm, now that I look at it, there are not that many tropical-inspired bird Pokemon, I mean we have your typical Pigdey and Tranquill, but things like Braviary and Talonflame... no (both eagle based). More industrialized and unnatural (this area hasn't been lived in by people for more than 40 years) Pokemon like Muk, Gengar, Honedge and Alakazam won't be common here. Not many lakes around and the sea is thousands of kilometers away, so Clauncher and Jellicent won't be found. No rocky mountains around either, only jungle hills and big(20+ meter) rocks, so Aggron and the such. Fire and Electric-types would not like it much here, unless in a jungle theme like Emolga. No snow or ice here (because of heat issues) so yeah those are out. Same for forest based Pokemon like Sawsbuck and Stunky. Also no sand. That only leaves the themes I stated above and I'll just cut out other continent Pokemon, like Pancham.
