People of mixed Klingon and Tellarite descent in the 32nd century, the best known being the pirate Nus Braka, leader of the Venari Ral in Star Trek: Starfleet Academy.
Klingarite is the term used in Starfleet Academy for someone who is part Klingon and part Tellarite. It reflects how far the old peoples of the galaxy have mingled by the 32nd century, in the years after the Burn.
The only Klingarite seen so far is Nus Braka, played by Paul Giamatti, who is introduced in the first episode, Kids These Days. He leads the Venari Ral, a pirate band that preys on a weakened Federation, and he has a long and bitter history with Nahla Ake, the Academy's chancellor and captain of the USS Athena.
Braka has the brow ridges of a Klingon and the heavy features of a Tellarite, and he is as fond of argument as he is of violence. He returns in Come, Let's Away, where he lures Starfleet into a trap.
