A previously undocumented Sesiidae hind wing impression has been identified in dacitic tufflayers of Badenian age (Middle Miocene) from the Csiga Csiga-dűlő locality, situated in the western part ofMagyaregregy, in the northern foreland of the Mecsek Mountains (Southern Hungary). The fossil was dis-covered on June 14, 1996, on the surface of a bedding plane and subsequently deposited in the NaturalHistory Collection of Komló. Despite its potential paleontological relevance, the specimen remained un-published and largely forgotten for nearly three decades. This contribution presents the first formal docu-mentation of the find, including its geological context and a drawing of the wing impression prepared bythe original collector. The occurrence of insect fossils in volcaniclastic deposits of the Pannonian Basin israre, and this specimen adds valuable data to the sparse Miocene insect record of the region. Only two un-described Sesiidae were previously known, a compression from the late Oligocene of France and an inclu-sion in amber of uncertain origin. The new fossil belongs to the tribe Paraglosseciini, now now-a-day absent inWestern Palaearctic but present in Eastern Palaearctic, Indo Indo-Malayan, and Australasian regions.
