Abstract
The Anisopodidae Knab, 1912 is an ancient family of Diptera, with several extant genera well represented in the Paleogene. It is especially the case for the genus Mycetobia Meigen, 1818, known by several Baltic amber species (Wojton et al., 2019a, b). On the contrary, the extant paleotropical genus Mesochria Enderlein, 1910 is currently known by two fossil species from the Eocene Chinese amber and the Miocene Dominican amber (Grimaldi, 1991; Szadziewski et al., 2016). Here we report the first European species of Mesochria, from the lowermost amber of Oise (France), greatly extending the past distribution of this genus.
