Abstract:—Catopsis (Tillandsioideae) comprises epiphytic and rupiculous herbs distributed throughout Mexico, CentralAmerica, the Caribbean, and northern South America. The genus is more diverse in Mexico, where more than 85% of its species exist. Catopsis is characterized by its seeds with an apical appendage formed by numeroushairs born at the chalazal end. Most of the species are dioecious, although some taxa are monoecious or trioecious.The objectives of the present revision were to perform a taxonomic treatment of the genus, as well as to propose a hypothesis of phylogenetic relationships among the species. The study was based on a review of 1,900 herbariumspecimens corresponding to 1,548 collections, from 16 herbaria, as well as examining live plants. Phylogenetic analyses were conducted using 70 morphological characters and DNA sequences of the plastid genes rps16 andmatK. Catopsis is a monophyletic group that comprises 27 species, five of which are new to science and are in the process of being described. Catopsis compacta, C. occulta, C. paniculata, C. pendula, C. wawranea and one new species are endemic to Mexico, whereas C. pisiformis is endemic to Panama and C. werckleana to Costa Rica. The citation of the original publication, as well as the lectotypification of the genus are clarified. The monographpresented here provides a broad synthesis of previously published information and includes data on nomenclature, morphology, geographic distribution, and phylogeny, which complete the descriptions and synonymies ofthe species. It also includes an identification key, as well as descriptions and distribution maps for each species.
