Rallus longirostris, R. crepitans and R. obsoletus (del Hoyo and Collar 2014) were previously lumped as R. longirostris following AOU (2000). Rallus elegans and R. tenuirostris (del Hoyo and Collar 2014) were previously lumped as R. elegans following AOU (2000). Sibley and Monroe (1990, 1993) included tenuirostris within R. longirostris.

Population justification: The population is estimated to number over 20,000 individuals (Wetlands International 2014).

Trend justification: The overall population trend is decreasing owing to conversion of its mangrove and wetland habitats (G. Kohler in litt. 2014).
