Stackelberginia cerberus sp. nov. (Diptera: Asilidae) is described from the Amargosa desert (USA: Nevada) and compared to related taxa. This is the first record of the genus in the Western Hemisphere; other species live in the deserts of central Asia. Stackelberginia Lehr is proposed as the sister taxon to Lasiopogon Loew in the subfamily Stichopogoninae based on morphological characters and a Bayesian species tree estimated from one mitochondrial (COI) and three nuclear protein-coding loci (AATS, PEPCK, wingless). Stackelberginia has the medially divided epandrium and rotated hypopy-gium of Lasiopogon, but the facial gibbosity is flat, macrosetae of thorax, head, and legs are unusually long, and phenology peaks in late autumn.
