Description
Merdigera obscura shells.

The 8.5-10.5 x 3-4 mm shell has 6 slightly convex whorls with deep suture. The apertural margin is reflected and white, not connected by a callus or white layer at the parietal side. The shell colour is evenly brown. The surface has dense radially striations.

The animal is dark brown, lighter laterally and on the foot. The upper tentacles are long, the lower tentacles length is 1/4 of upper tentacles. The animal crawls with the shell in a very high position and not much bent to the right side. Juveniles and adults often have camouflage.
