Four are described and illustrated as new species namely, Opisthorchis philippinensis from the jack snipe (Lymnocryptes minimus) and the common moorhen (Gallinula chloropus lozanoi); Brachylaima (Brachylaima) tubanguense from the Philippine coucal (Centropus viridis viridis); Lyperosomum (Lyperosomum) mindorense from the slaty-legged crake (Rallina eurizonoides eurizonoides) and Lyperosomum (Lyprerosomum) velasquezae from the Philippine jungle fowl (Gallus gallus philippinensis).
