Range DescriptionR. trachyrhynchus is endemic to New Caledonia. It is restricted to the southern half of Grande Terre. It is known from five or six widely scattered and isolated populations between Presqu'ile de Pindaï and Mt Aoupinié in the north and the Goro district in the south. This species also inhabits the Isle of Pines and the surrounding islets. Occurs from 5 up to 500 m asl.
The extent of occurrence is estimated at approximately 9,000 km² and the area of occupancy at <150 km².
[Extent of occurrence was based on a crude measure of overall length times width of the most distant known locations (a rough measure of the line around the points), except for very widespread species where the published areas of the islands were taken. Area of occupancy is a contraction of that rough estimate for extent of occurrence based on where habitat remains.]
