Quoy and Gaimard, 1830,
Has sometimes been treated as conspecific with A. syrinx, and sometimes also with A. rehsei, but differed from both in distinctly larger size, much longer bill and song. Previously considered conspecific with †A. nijoi, †A. yamashinae and †A. astrolabii, while A. hiwae was often treated as a synonym of luscinius (sensu stricto); but all are now separated primarily on basis of comprehensive genetic data#R#R. Monotypic.
Guam, in S Mariana Is.
Restricted to freshwater wetland and wetland-edge vegetation, this species is thought to have succumbed to a combination of predation by the introduced brown tree-snake (Boiga irregularis), wetland destruction, pesticide use and major fires. The last sighting was in 1969, and searches in the 1970s and 1980s failed to find it#R#R#R#R.
