Dopterians
Star Trek: The Next Generation
Episode: TNG 273 - Firstborn
A humanoid race related to the Ferengi and, like them, unsensible to telepaths — or at least the Betazeds. The U.S.S. Enterprise crew encountered a Doptherian named Gorta, while searching for the Duras sisters. Constable Odo knows of them from various dealings on space station Deep Space Nine. In appearance their bald heads are covered with a slight mottling, a Ferengi-like nose and a Lyseppian-like extended cranium and a ridge from the rear of the head to the stubby, pointed earflap.
