''Melanochlamys'' is a genus of headshield slugs in the family
Aglajidae
Aglajidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea
The order Cephalaspidea, also known as the ...
. Despite the appearance of its species, this genus must not be confused with
nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs, belonging to the order Nudibranchia, that shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have b ...

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.

It differs from the other genera in Aglajidae by its external cylindrical body form with small
parapodia
In invertebrates, the term parapodium ( Gr. ''para'', beyond or beside + ''podia'', feet; : parapodia) refers to lateral outgrowths or protrusions from the body. Parapodia are predominantly found in annelids, where they are paired, unjointed late ...
