          Abstract

          Abstract Jiménez, J. E.; O. Oyuela-Andino, J. H. Bonilla & M. A. Blanco. 2023. Aristolochia hondurensis (Aristolochiaceae), a new species from Honduras. Darwiniana, nueva serie 11(1): 31-42. Aristolochia hondurensis, a new species of Aristolochia series Hexandrae subseries Hexandrae, endemic to Honduras, is described and illustrated. It is a species morphologically similar to Aristolochia anguicida, from which it is distinguished by its much larger flowers (in all dimensions) with an oblong, attenuate, erect perianth limb, perpendicular to the tube. Comments about its distribution, habitat, phenology, conservation status, and distinction from morphologically similar species, and a dichotomous key of the species present in Honduras belonging to the subseries Hexandrae are provided. The new species is known from only two populations and is not known to occur in any protected area; it is provisionally categorized as Critically Endangered (CR) according to IUCN Red List criteria. Previous reports of A. inflata for Honduras appear to be unsubstantiated by herbarium specimens.

          Resumen Jiménez, J. E.; O. Oyuela-Andino, J. H. Bonilla & M. A. Blanco. 2023. Aristolochia hondurensis (Aristolochiaceae), una nueva especie de Honduras. Darwiniana, nueva serie 11(1): 31-42. Se describe e ilustra a Aristolochia hondurensis, una nueva especie endémica de Honduras, perteneciente a la serie Hexandrae subserie Hexandrae. Esta especie es morfológicamente similar a Aristolochia anguicida, de la cual se distingue por sus flores mucho más grandes (en todas sus dimensiones), con el limbo del perianto oblongo-atenuado y erecto, perpendicular al tubo. Se proporcionan comentarios sobre su distribución y hábitat, fenología, estado de conservación, observaciones taxonómicas, distinción con especies morfológicamente afines, y se proporciona una clave dicotómica de las especies presentes en Honduras que pertenecen a la subserie Hexandrae. La nueva especie se conoce solamente de dos poblaciones, ambas por fuera de áreas protegidas; provisionalmente se categoriza como en Peligro Crítico (CR) de acuerdo a los criterios de la Lista Roja de la UICN. Informes previos de A. inflata para Honduras aparentemente no tienen respaldo en especímenes de herbario.
