Abstract
Description
Se describen e ilustran dos nuevas especies del género Teagueia, T. barbeliana y T. puroana. Se discuten sus afinidades, su importancia para la ciencia, y su conservación. Las especies más cercanamente emparentadas con las nuevas son T. alyssana, T. sancheziae, T. cymbisepala, y T. jostii, que al igual que las nuevas, son endémicas a las alturas (>3100m) de la cuenca alta del Río Pastaza en los Andes Orientales del Ecuador. Teagueia barbeliana se distingue por sus sépalos y pétalos redondos, sus sépalos laterales unidos hasta la mitad de su longitud, y las alas en el ápice de la columna. Teagueia puroana se distingue por sus pétalos y sépalos con colas largas.
Two new species of Teagueia, T. barbeliana and T. puroana, are described and illustrated. Their relationship to other Teagueia, their scientific importance, and their conservation is discussed. Closest relatives are T. alyssana, T. sancheziae, T. cymbisepala, and T. jostii, and like them, the new species are high- elevation (>3100m) endemics of the upper Río Pastaza watershed in the eastern Andes of Ecuador. Teagueia barbeliana differs from its relatives by broad rounded flower parts, lateral sepals connate for half their length, column apex winged. Teagueia puroana differs from relatives by its long-acuminate petals and sepals.
