Conopoderas yamashinae


, 1931,

Pagan Island


Previously considered conspecific with †A. luscinius, †A. nijoi and †A. astrolabii, but all now separated primarily on basis of comprehensive genetic data#R#R. Monotypic.


Pagan, in Northern Mariana Is.

Became extinct on Pagan Is, where it was largely confined to freshwater wetland and wetland-edge vegetation around the island’s two lakes, before 1981. Local inhabitants maintain that populations persisted in the wetlands until the 1960s, but intensive searches in the early 1980s and 1990s confirmed its extinction#R, after surveys in the late 1970s had found no evidence for its continued presence#R. Habitat loss as a result of wetland drainage for agriculture and grazing by livestock is thought to be the main cause of its disappearance. Predation by rats and cats is likely to have been a contributory factor.
