The holotype and only known specimen of Pseuderythrinus rosapinnis Hoedeman, 1950 from Surinam is reexamined for the dentition of its palatal arch. Its morphometric and meristic data are compared with four species of erythrinids from the Guianas. Pseuderythrinus rosapinnis turns out to be a synonym of Hoplerythrinus unitaeniatus.
