Melanochlamys is a genus of headshield slugs in the family Aglajidae. Despite the appearance of its species, this genus must not be confused with nudibranchs. ^[2]

This genus was first described by Cheeseman in 1881 but later malacologists considered it a junior synonym of Aglaja Renier, 1807, until the genus was reinstated by Rudman in 1972. ^[3]

It differs from the other genera in Aglajidae by its external cylindrical body form with small parapodia, the shape of its small, curved and strongly calcified shell, its alimentary canal with a rigid, non-eversible buccal bulb, and the reproductive system with a short duct to the exogenous ( = originating from the outside) sperm sac and a characteristic penis. ^[3]
