* The original spelling of this generic name as given by Latreille in 1804, when he founded the genus was Smynthurus It would appear to have been derived from the Greek words Sminthos (meaning a mouse) and oura (a tail), in which case the amendment which has been made by most authors to the spelling Sminthurus is grammatically correct and allowable under the International Rules of Zoological Nomenclature.
