I found this doing evolutions. Meowstic-M has a pokedex entry where on the other hand Meowstic-F simply does not exist in the Pokedex. I evolved a female Espurr into Meowstic-F and did not get any evolution data for it, the number stayed the same. So either we are missing the entry of Meowstic-F in the Pokedex or it should be only "Meowstic" in the Pokedex regardless of gender (That's how it is in the original nintendo pokedex).
