Five new species of Eugenia L. (Myrtaceae) are proposed from New Caledonia: Eugenia amosensis N. Snow, Eugenia homedeboana N. Snow, Eugenia sicifolia J.W. Dawson & N. Snow, Eugenia tchambaensis J.W. Dawson & N. Snow, and Eugenia tiwakaensis J.W. Dawson & N. Snow. The new species are provided with detailed species descriptions, digital images, comments on morphology and ecology, and conservation assessments following IUCN Red List Categories and Criteria. The following new combinations are proposed: Eugenia gomonenensis (Guillaumin) J.W. Dawson & N. Snow, Eugenia lotoides (Guillaumin) J.W. Dawson & N. Snow, Eugenia styphelioides (Schltr.) J.W. Dawson & N. Snow, and Eugenia poimbailensis (Guillaumin) J.W. Dawson & N. Snow. The new name Eugenia veillonii N. Snow & Callm. is proposed and its basionym is lectotypified. Lectotypes also are designated for Eugenia mendute Guillaumin, Eugenia ovigera Brongn. & Gris, Eugenia horizontalis Pancher ex Brongn. & Gris and its synonym Myrtus aemulans Schltr., as well as for Myrtus gomonenensis Guillaumin, basionym of Eugenia gomonenensis.
