Abstract	Articulated skeletal remains of tetraodontid pufferfishes are rather rare in the fossil record. To date, the only known relatively entire fossil pufferfishes are the few specimens belonging to the extinct genera Eotetraodon and Archaeotetraodon, from the Eocene and Oligo-Miocene, respectively. A new genus and species of tetraodontid pufferfish, Leithaodon sandroi gen. et sp. nov., is described herein from the Middle Miocene fish-bearing corallinacean limestone of St. Margarethen, Burgenland, eastern Austria. This new taxon is based on a single, nearly complete specimen that exhibits a unique combination of features (sphenotic articulating with the supraoccipital, lateral ethmoid in contact with the palatine, anal fin origin slightly behind the posterior end of the dorsal fin base, 11(12) dorsal fin pterygiophores, but only six anal fin pterygiophores, and slender elongate ventral postcleithrum) that distinguish it from all other tetraodontids, fossil and extant. The paleoecology of this new taxon also is discussed.Artikulierte Skelettreste fossiler Kugelfische (Tetraodontidae) sind sehr selten. Die einzigen bisher bekannten und verhältnismäßig vollständigen fossilen Kugelfische gehören den fossilen Gattungen Eotetraodon und Archaeotetraodon an, erstere sind aus dem Eozän, letztere aus dem Oligo-Miozän bekannt. In der vorliegenden Studie wird eine neue Gattung und Art der tetraodontiden Kugelfische, Leithaodon sandroi gen. et sp. nov., aus dem mittelmiozänen Leithakalk von St. Margarethen, Burgenland (Österreich) beschrieben. Leithaodon sandroi gen. et sp. nov. basiert auf einem einzigen Exemplar, welches nahezu vollständig erhalten ist. Aufgrund seiner speziellen Kombination von Merkmalen (Sphenotic mit Supraoccipitale artikuliert, laterales Ethmoid im Kontakt mit dem Palatinum, Insertion der Analflosse etwas hinter dem hinteren Ende der Basis der Dorsalflosse, 11(12) Pterygiophoren der Dorsalflosse, sechs Pterygiophoren der Analflosse, schlankes längliches ventrales Postcleithrum) kann das neue Taxon von allen anderen fossilen und rezenten Vertretern der Tetraodontidae unterschieden werden. Die Paläoökologie der neuen Gattung und Art wird diskutiert.
