Brotheus praemorsus (Thunberg, 1799), an ancient 'non-established introduction' in Britain (Curculionoidea: Brachyceridae)

摘要

Curculio species number 49 in Marsham (1802: 255) is C. porcatus. The weevil is very distinctive and Stephens (1831: 152-154) erected a new genus for it-Brotheus. However he later (Stephens, 1839: 251) referred Marsham's species to Rhytirhinus Sch?nherr and did not mention his own Brotheus. He placed both Rhytirhinus and porcatus in parentheses, as they appeared 'to have been improperly introduced into the British lists'.
