SYNOPSIS. Blood films made from the “shoveller duck”, Anas clypeata Linnaeus 1758, in Lin‐pien Ping‐tung Hsien, Taiwan, showed a new species of avian malaria parasite, for which the name Plasmodium anasurn is proposed. This species is characterized by elongate gametocytes often closely resembling Huemopvoteus , about 15 merozoites per segmenter (although such stages were too few for really accurate counts), and trophozoites and schizonts which very often surround the extremities of the host cell nucleus in U‐shaped fashion. Pigment is abundant, appears early, and is very dark. The host cell shows little or no alteration. No infected reticulocytes or blood cells other than erythrocytes were observed.
