CURRENT STATUS: junior synonym of Eumerus ruficornis Meigen, 1822 (Peck 1988: 161, Belcari et al. 1995a: 16). REMARKS: Rondani (1850a: 124) described both sexes of Eumerus barbiventris without specifying the exact number of specimens and not giving a range of lengths, but presumably from more than one specimen because he wrote: “ non rarus [not rare]”. We found 11 syntypes in this study.Published as part of Sforzi, Alessandra & Sommaggio, Daniele, 2021, Catalog of the Diptera types described by Camillo Rondani, pp. 1-438 in Zootaxa 4989 (1) on page 248, DOI: 10.11646/zootaxa.4989.1.1, http://zenodo.org/record/498062
