Abstract

Parametriocnemus lausannensis Widmann, Marle & Brodin sp. n. is described and figured based on five barcoded specimens collected in the city of Lausanne, Switzerland. This species is morphologically similar to P. stylatus (Spärck, 1923), P. lundbeckii (Johannsen, 1905), P. scotti (Freeman, 1953) and P. adzharicus Kownacki & Zosidze, 1973 which is raised here from subspecies to species level. Males of P. lausannensis can be separated from related species by the squarish shape of the inferior volsella and by its DNA barcodes.
