Nososticta digimu sp. nov., a new damselfl from Papua New Guinea (Odonata: Platycnemididae)

A new species of damselfly, Nososticta digimu sp. nov., is described from Southern Highlands Province, Papua New Guinea, and its affinities are discussed. It belongs to a group of Nososticta in which the male synthorax exhibits discrete patches of blue, and the tip of the male abdomen is blue. The new species differs from its congeners exhibiting these characters either by lacking a transverse blue frontal bar from eye to eye or by its much larger blue ante-humeral patch that extends anterior to the mesokatepisternum. Nososticta digimu sp. nov. represents the 85th species of the genus and is currently known only from a single location in the Digimu River catchment. The supra-specific term Nososticta conifera complex is introduced.
