I don't mean simply same total. I mean each species in the group have the same value in every single base stat. The only ones I know are Glalie/Phione, Cascoon/Silcoon, and Xerneas/Yvetal. Don't include legendaries with 100 all around because those are obvious.
EDIT: Sorry for the misunderstanding. I don't mean individual species that have the same value for all the base stats. I wanted groups of two or more Pokemon that have the same stats, like how Silcoon and Cascoon both have 50 hp, 35 attack, 55 defense, 25 SpA, 25 SpD, and 15 speed. Again, sorry.
After staring at Pokemon stats for like forever... ;~;
