I did a species count once for MH it's not done though. The item based species and plants you see in game are throwing my count off.

167(38 being from Frontier)(161 if not counting MHO monsters and Barioth, Ludroth and Blango Sub are questionable) Hunt able species. for example "Beru and Dora are the same species along with all their variations as stated in game" same for "Tigrex and Brute Tigrex" Brute Tigrex being just a volcanic normal Tigrex.
