||Pareudiastes silvestris (del Hoyo and Collar 2014) was previously placed in the genus Gallinula.
||27 cm. Medium-sized, almost tail-less, flightless rail. Black plumage with bluish gloss on head and neck and brown wash to mantle and wings. Red legs and bill. Blue-grey frontal shield. Similar spp. Spotless Crake Porzana tabuensis much smaller and has black bill. Purple Swamphen Porphyrio porphyrio has white undertail-coverts and frontal shield concolorous with bill. Rufous-tailed Water-hen Amaurornis moluccanus has dull greenish bare parts and rusty vent. Voice Unknown. In 2004, calls thought possibly to belong to this species were reported. They were of a cat-like meowing sound mealowl, high in pitch, reptitive, continuous and dropping at the end. Hints Search remote areas with the aid of local hunters.

This species has not been directly recorded by western scientists since 1953 despite recent surveys lasting several weeks. However local hunters and villagers report the species as extant but very rare. The already small population is likely to have declined further as a result of depredation by introduced mammalian predators. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered.

|Range Description:||Pareudiastes silvestris is known to western science only from the type-specimen collected in 1929, and a subsequent observation of one in 1953 on Makira (= San Cristobal), Solomon Islands. The 1929 collectors failed to secure more specimens and concluded that the species was already rare (Taylor and van Perlo 1998). In 1953, it was reported to be well-known to guides from Ghoghe village and to be not uncommon (Cain and Galbraith 1956). Some hunters and residents of hill villages and coastal villages on the southern weather coast report encountering this species very rarely, usually when caught or treed by dogs (J. M. Diamond in litt. 1987, Lees 1991, Buckingham et al. 1995, J. Waihuru verbally 1998, R. James in litt. 2003, 2011, C. Collins in litt. 2008, Danielsen et al. 2010). Specific surveys for this species in 2015-2016, including >1000 days of camera-trapping, gathered more reports of the species persisting in very small numbers but no direct evidence (Dutson 2016, Mittermeier et al. in prep.).|
