Kovassii

The Kovassii are a humanoid species native to either the Alpha Quadrant or Beta Quadrant. They are strict followers of protocol and are offended by the display of bare hands. In 2370, they arrived at Deep Space 9 to negotiate access to the Bajoran Wormhole. (DS9 novel: Betrayal)

''One of the Kovassii is described as having silver hair and silvery eyes. Two of them are said to be wearing topknots. Whether these are traits of the species or individual traits is not known.''
