NEW TAXA IN PAPHIA AND DIMORPHANTHERA ( ERICACEAE ) IN PAPUASIA AND THE PROBLEM OF GENERIC LIMITS IN VACCINIEAE

New species of  Ericaceae  recently collected in Papua New Guinea necessitate a re-evaluation of the status of  Agapetes  subgenus  Paphia  section  Paphia . The combination of molecular and morphological data confirms that  Agapetes , currently a genus of about 100 species from Fiji, New Caledonia and Queensland to mainland SE Asia, and most diverse in the latter area, cannot be maintained in its current circumscription. Various taxonomic solutions that do justice to our current knowledge of the morphology and relationships of the two main parts of the genus are discussed. The reinstatement of  Paphia  does least violence nomenclaturally. All 23 taxa recognized in  Paphia  are listed, 14 new combinations of  Agapetes  from the New Guinea–SW Pacific area are made in  Paphia , three new species are described ( P. megaphylla, P. vulcanicola  and  P. woodsii ), and an incompletely known taxon is characterized. A key to all taxa is presented. In  Dimorphanthera , five new species are described ( D. angiliensis, D. anomala, D. antennifera, D. cratericola  and  D. inopinata ), three reduced to synonymy, one reduced to a variety and one variety recognized as a species ( D. continua ). A key to the 87 taxa currently recognized in the genus is presented.
