The Hova gallinule (Hovacrex roberti) is an extinct bird in a monotypic genus in the rail family. It was a large gallinule that was endemic to Madagascar. About the size of the Tasmanian nativehen, it was originally placed in the same genus, Tribonyx. Hovacrex may also be synonymous with Gallinula.[1] The lack of wing bones in the subfossil material found at Sirabé in central Madagascar makes it uncertain as to whether the species was flightless.[2]
