Tijdschrift voor Entomologie 159 (2016) 97–142 Syrphidae (Diptera) of Surinam: Eristalinae and synthesis Menno Reemer The fauna of Eristalinae (Diptera: Syrphidae) of Surinam is reviewed. Accounts are given for 81 species of Eristalinae. These include larval rearing records for species of Ceriogaster Williston, 1888, Copestylum Macquart, 1846, Lepidomyia Loew, 1864, Ornidia Lepeletier & Serville, 1828, and Quichuana Knab, 1913. Keys are given for the Surinamese species of Meromacrus Rondani, 1848 and Palpada Macquart, 1834. Two new species are described: Lepidomyia adriaanpeteri sp. n. and Meromacrus doesburgi sp. n. A new synonymy is proposed: Meromacrus fucatus Hull, 1930 = Meromacrus ceres Hull, 1942 jun. syn. n. All species are figured with photographs. Compared with the checklist of Van Doesburg (1966), 26 species are added and four are removed. Several possibly new species are left unnamed, pending required taxonomic revisions. In total, 183 species of Syrphidae are now known from Surinam: 60 Syrphinae, 42 Microdontinae, and 81 Eristalinae. Concluding remarks are made on the number of species expected to occur in the country.

Adult Eristalinae are flower monophyly of the Eristalinae is still a matter of debate.
