Old World Warblers (Sylviidae)

Island Leaf-warbler (Phylloscopus poliocephalus) - HBW 11, p. 671

French: Pouillot des îles German: Papualaubsänger Spanish: Mosquitero Isleño
Other common names: New Guinea Leaf-warbler; Numfor Leaf-warbler (maforensis)

Taxonomy: Gerygone? poliocephala Salvadori, 1876, Arfak Mountains, Vogelkop, New Guinea.
Relationships uncertain. Recent DNA studies suggest possible sister relationship to P. amoenus. Previously thought to form a superspecies with P. trivirgatus, P. sarasinorum, P. presbytes and P.makirensis, but this is not supported by findings from recent molecular-genetic studies. Birds discovered on Taliabu (Sula Is), in Sept 1991, may represent a hitherto undescribed race. Detailed review required. Nineteen subspecies currently recognized.
