title: A new species of Espeletiopsis (Millerieae, Asteraceae) from Colombia.
abstract: A new species of Espeletiopsis was found in two small páramos of Norte de Santander, Colombia. The species is named Espeletiopsis diazii honoring the contributions of Santiago Díaz-Piedrahita in recognition of his vast knowledge of the Compositae in Colombia. This is a very distinctive species, markedly different from most of the Espeletiopsis present in Colombia. The new species is closely related to Espeletiopsis caldasii and Espeletiopsis santanderensis, but differs in having (1-)4-6(-7) capitula, with very short peduncles, and capitula arranged in a compact or densely glomerate cyme. With a total distribution area of less than 75 km(2), this species is probably critically endangered or imperiled.
