Munna are small species with short bodies, wider at the head end. The antennae are as long or longer than the body, and the eyes are situated on lateral projections. Pereon segments 5 to 7 are small. The first pair of legs are smaller and are held under the body, the other pairs of legs are long. Uropods are small.
M. limicola (females up to 3 mm) is characterised by prominent eye projections, fine, elongated legs, especially towards the rear, and a large, oval pleotelson relative to other species.
