The Napeans were a partially empathic race from the Alpha or Beta Quadrant. Their physical appearance was similar to most humanoids except for their large, leaf-shaped forehead ridge.
Starfleet Lieutenant Daniel Kwan was a half-Human and half-Napean hybrid. (TNG: "Eye of the Beholder")
A crewmember serving on board the Nebula-class USS Lexington was also of Napean descent. (DS9: "Explorers")
Another Napean was part of Kasidy Yates' crew aboard the Xhosa. (DS9: "Family Business")
