Résumé
A new species of Coelonotus, a freshwater pipefish, is described on the basis of six specimens from the Gavuvu River of West New Britain Island (Papua New Guinea). It differs from other Coelonotus species by a combination of morphomeristic values including: number of dorsal fin rays (45-47), number of subdorsal (4-5) and tail rings (35-37). The Folmer DNA barcode fragment of the COI mitochondrial gene shows that this new species is indeed a different genetic lineage from other Coelonotus species of this area.
