Kesprytt
From Memory Alpha, the free Star Trek reference.
The Kesprytt are a species native to the planet Kesprytt III. They are divided into two rivaling nation-states known as the Kes and the Prytt. In 2370, the bigger part of this species (the Kes) applied for associate Federation membership, but this request was denied. Due to the long conflict between the two nations, all Kesprytt have developed a strong sense of paranoia and xenophobia. (TNG: "Attached")
