An updated catalogue of the Histeridae (Coleoptera) of Sardinia, with faunistic, zoogeographical, ecological and conservation remarks * Author Penati, Fabio text Zootaxa 2009 2009-12-22 2318 197 280 journal article 1175-5326 Saprinus ( Saprinus ) planiusculus Motschulsky Literature data. “ Sardinia ” ( Vienna 1980 ; Audisio et al . 1995 ; Penati & Vienna 2002 ; Yélamos & Lackner 2004 ). Notes. This species was for a long time and by many authors considered a synonym of Saprinus semistriatus (see for example Luigioni 1929 ), so no records ascribable with certainty to this species exist in the literature prior to Vienna (1980) . Moreover, in Italy it is widespread and very frequently sympatric with Saprinus semistriatus and S . subnitescens (see Penati & Vienna 2005 , 2006a ), with which it has often been confused (see notes under S . subnitescens ). This situation does not give a clear and definitive picture of the Italian distribution of S . planiusculus . Nevertheless, no Sardinian specimen was found in the examined collections and I therefore consider it as absent from the island, as already suggested by Penati and Vienna (2005 , 2006a ).
