Abstract:

Platystele apoloae, a new orchid species is here described and illustrated. It was discovered in semi-deciduous premontane forest from Southwestern Ecuador, in the Amotape-Huancabamba zone. Information about its distribution, habitat, phenology, and conservation status is provided. The new taxon is compared with P. carl-lueriana, P. catiensis, P. cornejoi, P. ovalifolia, P. pedicellaris and P. propinqua, species to which it is morphologically similar.

Compared to previous studies the average number of Brunellia spp. per Andean department doubles from two to more than four species. Our data indicate a center of species richness and endemism in northern Peru, namely the Amotape-Huancabamba Zone (AHZ). Furthermore, distribution maps for all species are

The global scale explains general (paleo-) ecological factors valid for most parts of the humid tropics, addressing various hypotheses and theories, such as the "greater effective evolutionary time", constant input of "accidentals", the "seasonal

Molecular and morphological data show that the new species belongs to the Nasa triphylla group.
