Tanugan

The Tanugans are a sapient humanoid species native to Tanuga IV. They look similar to Humans, but can be distinguished by having three pairs of ridges over their eyebrows.

Culture and society
The Tanugan justice system differs from that employed by the United Federation of Planets in that accused parties are presumed to be guilty until they can prove their innocence.
