Recently a paper was published with a new robber fly species from Sint Eustatius: Efferia exaggerata. The species-name refers to the extremely large terminalia, which, in flight, the male appears to drag behind him. There was one other species of Efferia known from the Lesser Antilles: E. nigrimystacea, which was encountered on Sint Eustatius as well. Furthermore several specimens of the species Ommatius prolongatus were found on the island, which was only known from a single female described from Montserat. In the present paper the male is described as well. With these three species newly recorded from Sint Eustatius, a small contribution to the knowledge of the biodiversity of the Dutch
Caribbean.
