ABSTRACT: Four new Fosterella species from Bolivia are described and illustrated: F. fuentesii, F. now ickii, F. rexiae (Andes), and F. yuvinkae (eastern lowlands, Chiquitano mountains). Fosterella petiolata, F. weberbauer! (re-established), and F. windisch!! are recorded as new species for Bolivia. Fosterella graminea and F. heterophylla are recorded for the first time since the type collection. Additional information on morphological variation and distribution of other species is provided. The number of described Bolivian Fosterella species rises to 27. Thus, Fosterella now ranks third in Bolivia (after Tillands!a and Puya) in total number of species and percentage of endemic species of Bromeliaceae within Bolivia. Key words: Bromeliaceae, Fosterella, taxonomy, biogeography, Bolivia INTRODUCTION ical, biogeographic, and molecular study efforts, we seek conclusions regarding the mechanisms Based on the many descriptions of new spe of speciation and diversity generation within this cies or new records, Fosterella clearly belongs genus.
