Cyanoderma is a genus of passerine birds in the Old World babbler family Timaliidae. 
Many of these species were formerly placed in the genus Stachyris. 

Timaliidae, Timalia: The word "Timalo" originates in the Greek "Thimalos", which means "bird". This Greek root was adapted to Latin as "Timalus" and later to Portuguese as "Timalo".
The name combines the Ancient Greek kuanos meaning "dark-blue" with derma meaning "skin".
