3.1 mm to the rear of the wings. Matagalpa Province, Nicaragua, 1000 meters elevation, 4 January 2011. Resting on a leaf, cloud forest.
I would love to know even the family!

My notes say that this little fly was walking sideways, backwards, and forewards, with equal skill in all three. It was found on the top of a very large leaf near a very small strream.

Dear Stephen
Do you have another angle? special wings?
Maybe better about its identification by experts! :)

Thanks, Sara. Unfortunately I got only two images of the fly and the angle of the second photo is only a little different from the angle of the first. But here it is.

Perhaps Asteiidae...

This is
Stenomicra sp., in either Aulacigastridae, Periscelldidae, or Stenomicridae (Diptera.org says Periscelididae).
These flies are fairly common moving about in the fashion you describe on large leaves in Neotropical rain forests.
Here is a blog post Isaac Winkler wrote about this genus a short while ago which includes a video of their locomotory behavior.
