Abstract

The taxonomic delimitation is clarified between two species recently recognized as closely related but distinct, Diospyros clusiifolia (Hiern) G. E. Schatz & Lowry and D. fuscovelutina Baker, which can easily be confused based on morphology and eco-geography. A third entity, Tetraclis baronii H. Perrier, erroneously placed in synonymy over a decade ago under D. fuscovelutina, is resurrected by establishing a new combination, D. baronii (H. Perrier) H. N. Rakouth & Lowry. The diagnostic characters that distinguish these three taxa are presented and discussed, along with a risk of extinction assessment of D. baronii based on the IUCN Red List criteria, which indicates that its status is Near Threatened.

Nous clarifions la délimitation taxonomique entre deux espèces reconnues récemment comme étroitement apparentées mais distinctes, Diospyros clusiifolia (Hiern) G. E. Schatz & Lowry et D. fuscovelutina Baker, qui du point de vue morphologique et éco-géographique peuvent facilement être confondues. Une troisième entité Tetraclis baronii H. Perrier qui a été mise en synonymie il y a plus de 10 ans par erreur sous D. fuscovelutina est rétablie sous la nouvelle combinaison D. baronii (H. Perrier) H. N. Rakouth & Lowry. Les caractères diagnostiques qui permettent de distinguer les trois taxons sont présentés et discutés, ainsi qu'une évaluation du risque d'extinction de D. baronii selon les critères de la Liste rouge de l'UICN qui indique un statut de Quasi-menacé.
