Corybas neocaledonicus is an endemic terrestrial orchid found in the southern part of Grande Terre in New Caledonia. This species is known from Mont Do to Vallée de la Thy. It is found in humid forest or in shrubland on ultramafic substrate at an altitudinal range 500-1,150 m asl. Main identified threat is linked to habitat damage by invasive species (feral pigs). Its area of occupancy (AOO) and extent of occurrence (EOO) being estimated respectively to 52 and 1,899 km², Corybas neocaledonicus is considered Vulnerable (VU) using criteria B1ab(iii)+2ab(iii) with an estimation of six locations and an estimated decline of its habitat.
