Muzquizopteryx cohuilensis

Muzquizopteryx cohuilensis based on the nice skeletal by ~Dinomaniac -> [link]

The membrane is in a different configuration from my usual drawings, and attaches to the hind leg down all the way to the ankle(!). This was was suggested as a possible configuration by Mike Habib, and differs from the usual ankle attachment scenario in that the wing membrane meets the leg membrane meet at a sharp angle behind the elbow, which is a configuration found in birds (done with feathers rather than membranes, obviously).
