Burmeisteria (Digonus) accraensis, n. sp., occurs in a Devonian clay shale that crops out on the west African coast at Accra, Ghana. The species has been previously called Trimerus (Dipleura) dekayi Green, a species from the middle Devonian of New York State, but a study of 175 holaspid specimens and five meraspid specimens shows that an assignment to Burmeisteria (Digonus) Guerich, 1909 is greatly preferable and that the species is new.
