Abstract
Based on a specimen collected in Santa Catarina state, Brazil, the new species Oxypetalum kassneri is described and illustrated. Moreover, a molecular phylogenetic analysis allows to propose the revalidation of O. megapotamicum, a species currently placed in the genus Ditassa. The neotype of D. megapotamica and the lectotype of D. oxypetala are designated here.
Key words:
Ditassa megapotamica; lectotypification; neotypification; Oxypetalinae; Oxypetalum kassneri
