The literature had not mentioned this species of Oriental origin for some 73 years, until WENDT (1980) first re-examined and placed it in the genus Bruchidius SCHILSKY, 1905. Four years later BOROWIEC (1984) established Megabruchidius, based on the type species Megabruchidius bifoveolatus, which was there described as new. In that paper Megabruchidius tonkineus was moved into this genus. Later in the generic revision (BOROWIEC 1987) Megabruchidius bifoveolatus was synonymized with Megabruchidius dorsalis (FAHRAEUS, 1839). The European presence of Megabruchidius tonkineus was first recorded by WENDT ( 1980) from Germany (albeit with host record based on mistaken speculation), while Megabruchidius dorsalis had its first European record from Italy (MlGLIACCIO & ZAMPETTI 1989). Earlier studies have shown two bruchid species that develop in the seeds of woody plants in Hungary: Bruchidius villosus (FABRICIUS, 1792) in Laburnum anagyroides (SZENTESI 2006, SZENTESI & WINK 1991), and Acanthoscelides
