Oniscus serratus O. Fabricius, 1780 [ Amphipoda : Acanthonotozomatidae ] and Oniscus serratus J. C. Fabricius, 1787 [ Sphaeromatidae ]

Remarks: Oniscus serratus J. C. Fabricius 1787 is the type of Sphaeroma Bosc, 1801 by subsequent designation of Latreille (1810) fide ICZN Opinion 1574 (ICZN 1990) and the name was placed on the Official List of Specific Names in Zoology, although the date of Bosc in the Opinion was given as 1802 but was subsequently shown to be 1801 ( Low 2012). What has apparently escaped notice is that Oniscus serratus J. C. Fabricius, 1787 is a junior primary homonym of Oniscus serratus O. Fabricius, 1780 (as “ Oniscvs serratvs ”). However, the junior homonym cannot be replaced without an application to the ICZN (ICZN Article 23.9.5.) as the two taxa are currently in different genera as well as different orders within Peracarida as Acanthonotozoma serratum (O. Fabricius, 1780) ( Amphipoda ) and Sphaeroma serratum (J.C. Fabricius, 1787) ( Isopoda ).
