摘要

A revision of the Cohniella cebolleta complex from northern South America and the Lesser Antilles is presented. Five species are recognized in this complex. As circumscribed here, Cohniella cebolleta is restricted to northern Colombia and northern Venezuela. We describe and illustrate a new species, Cohniella macrocebolleta, endemic to eastern Venezuela, and propose two new combinations: Cohniella juncifolia, endemic to the Lesser Antilles, and Cohniella ultrajectina from southern Venezuela and the Guianas (Guyana, Suriname, and French Guiana). Detailed taxonomic descriptions are given for each species, including short accounts of their distribution and ecology, diagnostic characters, variational range, taxonomic comments, and material examined. Furthermore, a key, an appendix featuring diagnostic characters, and distribution maps for species complexes recognized in Cohniella and taxa recognized in the C. cebolleta complex are presented and discussed.
