Abstract
Phylogenetics work revealed that Aechmea subg. Chevaliera is not a monophyletic group. Seven species previously assigned to the subgenus form a clade with strong statistical support and in sister position to morphologically distinct members of other genera. We present morphological and phylogenetic evidence to segregate these seven species in a new genus named Karawata, which requires the following new combinations: Karawata depressa, Karawata gustavoi, Karawata hostilis, Karawata multiflora, Karawata nigribracteata, Karawata prasinata, and Karawata saxicola. Description of the new genus and its seven species, as well as a key for identification, distribution maps, and illustrations are provided.

Karawata J.R. Maciel and G. Sousa, gen. nov.
TYPE SPECIES: Karawata multiflora (L.B. Sm.) J.R. Maciel and G. Sousa.
Etymology:— The name Karawata refers to the vernacular name used to identify bromeliad plants by local people in Brazil, particularly species of subgenus Chevaliera, from which the Karawata species were segregated. The word is from Tupi (Karawatã or karawatá), a language largely used by native people before the colonization of Brazil.
