Microcotyle donavini is a species of monogenean, parasitic on the gills of a marine fish.

[2] This species was redescribed by Scott (1905) who gave one figure [3] and by Euzet & Marc in 1963, one hundred years later.

The haptor is symmetrical, and bears 86 clamps, arranged as two rows, one on each side.

The reproductive organs include an anterior oval genital atrium, armed with numerous small spines, a medio-dorsal vagina opening at 750 μm from the anterior extremity, a single ovary and 18-22 oval testes which are posterior to the ovary.
