Pinsir and Heracross joint, Lapras, Skarmory Stantler, Smeargle, Tauros and Miltank joint, Girafarig, Tropius, Absol, Maractus, Druddigon, Bouffalant

Ditto, Aerodactyl, Unown, Kangaskhan, Plusle, Minun, Torkoal, Spinda, Relicanth, Zangoose, Seviper, Pachirisu, Spiritomb, Rotom, Spiritomb, Basculin, Emolga, Sigilyph, Alomamola, Cryogonal, Heatmor, Durant
As for ones that already evolve, I'd be here all day. I really want Marowak to have one, but I doubt it ever will.
