||Gallirallus conditicius (Sibley and Monroe 1990, 1993), known only from the type reputedly collected in the Apiang Group of the Gilbert Islands, Kiribati, in 1861, is not recognised as a separate species but is treated as a synonym of H. sylvestris (Greenway 1952, Olson 1992).
Hypotaenidia sylvestris (del Hoyo and Collar 2014) was previously placed in the genus Gallirallus.
||34-42 cm (male), 32-37 cm (female). Large, olive-brown, flightless rail with bright chestnut wings. Olive-brown body, duller on underside. Indistinct, paler supercilium. Bright chestnut wings with narrow, dark brown bars on primaries and primary coverts. Long, decurved, pink bill, more brown towards tip. Red iris. Light pink-brown legs. Juvenile similar, but iris initially dark. Similar spp. Confusion unlikely. Buff-banded Rail G. philippensis is smaller, has bold black-and-white barring on underside, buff breast-band and clear white supercilium. Voice Loud, piercing, repeated whistle, often as duet.

||Garnett, S., McClellan, R., Pilgrim, J., Stattersfield, A., Taylor, J., Allinson, T & Symes, A.
This species is listed as Endangered as it has an extremely small population which is restricted to a tiny area of available habitat on one island. Conservation efforts have resulted in the stabilisation of numbers.

|Range Description:||Hypotaenidia sylvestris is endemic to Lord Howe Island (Australia). In 1788, it was found from sea-level to the tops of the two mountains on the island, but from the mid-19th century, it became restricted to the summits. In the 1970s the population comprised fewer than 10 breeding pairs (Brook et al. 1997). In the 1980s, following the eradication of introduced pigs Sus domesticus, birds were reintroduced to lowland sites, including isolated, steep, coastal palm forest at Little Slope, and lowland palm forests around the settlement. The highest densities are now surrounding the settlement and on Mt Gower, which support over half of the population. The population has reached the island’s carrying capacity (estimated at c.220 individuals [Brook et al. 1997]) and was estimated to be stable at around 220–230 birds and 71–74 breeding pairs (NSW National Parks and Wildlife Service 2002).|
