Distribution : D'après Taylor
et al. (2015): "wet forest in southern Venezuela and southern Guyana at 625 – 1500 m. Additionally several specimens from wet forests at 300 – 750 m on the eastern slopes of the Andean Cordillera of Peru are provisionally included here." D'après Delprete & Kirkbride (2016): "Tepui summits of southern Venezuela and Guyana." D'après Lachenaud
et al.
2022: "western Guyana, eastern Venezuela, and northern Brazil (Amazonas)
and apparently in disjunct populations in Amazonian Peru (Fig. 6); in tepui slope forests, sometimes on riverbanks,
mostly 700–1500 m but as low as 300 m altitude in Peru."
Statut biogéographique : D'après Lachenaud
et al.
2022: "A previous record of this species from French Guiana (Funk
et al. 2007,
as
Psychotria coussareoides) is presumably based on the specimen R.A.A. Oldeman & C. Sastre 88 (CAY), which is
Coussarea sp. No authentic material of
R. coussareoides from French Guiana has been seen by the authors."
