Psychotria sp. nov. "ponciae" is an endemic shrub, found in the Grande Terre moutain range from Mont Colnett in the North to Mé Maoya in the South of New Caledonia. It occurs in dense humid forest on volcano-sedimentary on ultramafic substrate at an altitudinal range 800-1,600 m asl. The main impact identified comes from past and potential future mining activities. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 52 and 1,134 km², Psychotria sp. nov. "ponciae" is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations lower than 10.
