Based on the long-standing confusion surrounding the name Dendropanax caucanus, a revised description and circumscription are here proposed, included a drawing. The species is excluded from the Flora of Costa Rica and Panama. Dendropanax bacchus, endemic to Costa Rica, is described and illustrated, and is provisionally assessed as Endangered [EN B2b(ii,iii)]. A lectotype is designated for Gilibertia caucana Harms.
