Psychotria pubituba is an endemic shrub, known in Grande Terre from Mandjélia to Roches Ouaïème in the north of New Caledonia. It occurs in dense humid forest on volcano-sedimentary substrate at an altitudinal range 500-1,100 m asl. The main impact identified may come from bushfires, however it is a forest species and population does not seem to decline. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 44 and 275 km², Psychotria pubituba is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality.
