Red List Status -

Protected species -

in Southern Province

Psychotria sp. nov. "moulii" is an endemic shrub of New Caledonia, found in a restricted area between Table Unio and Dogny in Grande Terre. It occurs in forest on volcano-sedimentary substrate at an altitudinal range 550-1,000 m asl. The main threat impacting this species comes from habitat degradation caused by invasive species (rusa rusa deer (Rusa timorensis) and Sus scrofa), in particular in Plateau Dogny and Parc des Grandes Fougères. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 32 and 85 km², while the number of locations are estimated to be four. Psychotria sp. nov. "moulii" is therefore assessed as Endangered (EN) with criteria B1ab(iii,v)+2ab(iii,v) with a decline of habitat quality and number of mature individuals.
