Do you know this Epidendrum species?

[Rosim_in_BR]

I acquired it two years ago without the specific epithet. The vendor said it was from Bolivia or Colombia, I don't remember well, and it could be a new species. Don't know... there are so many of these reed stemmed Epis.
Anyway, the plant is very characteristic in its small size (not higher than 3"), the crowded, pointing up leaves and the long, very long floral stem in relation to the plant height. The flowers themselves are tiny, half an inch across, and of an attractive, sweet pink coloration.
Any hint will be welcome!! Thanks!
