Abstract. Stylogaster Macquart, 1835 has been unknown in the fossil record until now, the only fossil conopid genus being Palaeomyopa Meulnier, 1912. Two Stylogaster specimens in amber from the American Museum of Natural History collection were studied and are described here. Both specimens, male and female, belong to a new species, S. grimaldii sp. nov., that is probably basal to at least the New World species with a short ocellar triangle. Photos and drawings of the new species are provided. The relationship with other Stylogaster species and ancient distributional patterns are briefly discussed.
