Buenas dias y recepción
(As you can see, your English is far better than my Spanish )
Not sure that I can help you with the identification of this one. But just wanted to welcome you!
Hopefully some one will be able to help you though you may find it will be classed as a Noid (No identification).
Flower shape does look a lot like my Miltonidium so I would guess it's something of that sort of hybrid. It may be impossible to get an exact ID, but for care info I would go with Oncidium type care.
I water mine when it just dries out and keep in it slightly brighter light than I would keep Phals.
I know there are a lot of hybrids between Miltonia and Oncidium (Miltonidium). I just wanted the name of this orchid.
May be, someone, know the name of this miltonidium.
