Abstract:

DC. contains five species, distributed from Costa Rica to Bolivia, with its main center of diversity in Ecuador. The revision includes a new species endemic to Costa Rica and Panama, E. Moran & V. A. Funk. Morphological and molecular data support as a monophyletic group, sister to . The phylogenetic analysis based on morphology used Ruiz & Pavon, (H.B.K.) Wedd., and DC. as outgroups. The phylogeny supports the monophyly of , but the relationships among the species within have only weak support. The genus is believed to be a recent radiation because of the morphological similarity among the taxa and their location in some of the youngest areas of the Andes.

El genero Erato contiene 5 especies, distribuidas desde Costa Rica hasta Bolivia, con su centro de distribución en Ecuador. Este revista incluye una nueva especie que es endémica de Costa Rica y Panamá, Erato costaricensis E. Moran & V. A. Funk. Datos morfológicos y genéticos confirman la hipótesis que Erato es un grupo monofilético hermano a Philoglossa. El análisis filogenético utilizó Munnozia Ruiz & Pavón, Chrysactinium (HBK) Wedd. y Philoglossa DC. como grupos externos. La filogenia confirma Erato como un grupo monofilético, pero los relaciones dentro de Erato solo tienen soportes débiles. Créen que el genero es una radiación reciente a causa de la semejanzas morfológicas entre de las especies y porque occurien en unos de los áreas mas jóvenes de los A ´ ndes.
