Abstract/Summary

-
A new species of Utricularia Section Orchidioides: Utricularia amotape-huancabambensis sp. nov. (Lentibulariaceae), endemic to Northern Peru is described and illustrated. It is known from two populations so far, both located in the Province Bongará, Dpto. Amazonas at ca. 2200 m altitude. The new species inhabits the páramo of the low white sandstone plateaus, an extension of the southern branches of the Condor mountain range in the southeastern part of the Amotape-Huancabamba phytogeographic zone. A diagnosis, description, etymology and an identification key covering the Andean and selected similar species of the section are presented. The distribution, habitat, ecology, associated flora, preliminary conservation status, an observed hybridization with sympatric U. unifolia and the affinities of the new species with other related taxa are discussed. The new species is known from two close-by populations in the same region and likely affected by anthropic pressure. Threatening changes in land use, resulting in habitat fragmentation or loss or changing water regimes in the course of climate change will have severe consequences for the sensitive páramo ecosystem and thus the populations of U. amotape-huancabambensis. Therefore, this new spectacular species of Utricularia is preliminarily considered Critically Endangered (CR).
