Justification of Red List category
The species is considered to have become extinct prior to the 1981 volcanic eruption on Pagan, though this event destroyed hopes of the species persisting to the present day. Surveys in the 1970s, 1980s, in 2000 and in 2010 all failed to find any trace of the species, its disappearance primarily a result of severe habitat modification.
