Resumen


Se describe e ilustra Drepananthus khaosoi sp. nov, una nueva especie del sur de Tailandia. Esta especie es morfológicamente más similar a D. ridleyi, especialmente en los pétalos muy estrechos y alargados, pero difiere en el tamaño de la lámina de la hoja, la base de la hoja, la forma y apariencia del monocarpio, el ancho del monocarpio, la longitud del estípite del monocarpio, el grosor del pericarpio y la disposición de las semillas. Los análisis filogenéticos moleculares de regiones de ADN del cloroplasto (exones matK y rbcL; intrón trnL; espaciadores intergénicos atpB-rbcLpsbA-trnH y trnL-trnF) incluyendo 18 especies de Drepananthus confirman la monofilia de Drepananthus, pero las relaciones dentro del género están en gran medida sin resolver, incluido el fallo en dilucidar un grupo hermano de D. khaosoi. El estado de conservación de la nueva especie se evalúa provisionalmente como En Peligro Crítico.
