T. fasciola var. mutina is an autochthonous orchid of New Caledonia. It is known only from two localities in the northern part of Grande Terre (main island) : Ténem and Balabio. T. fasciola var. mutina is found in wooded ravine on schist soil at an altitudinal range 10-100 m asl. This species can be potentially threatened by invasive species (Rusa deer and feral pigs) and its area of occupancy (AOO) and area of occurrence (EOO) are respectively equal to 12 and 53 km². Therefore T. fasciola var. mutina is considered Near Threatened (NT).
