Annotated checklist of the Coccinellidae (Coleoptera, Coccinelloidea) of Switzerland

An updated checklist of the Swiss species belonging to the family Coccinellidae is presented and briefly discussed. This checklist includes 81 species (82 taxa including the subspecies) and is based on 33'976 occurrences obtained from the identification of specimens held in museum and private collections, as well as from records taken from the literature. Exochomus oblongus Weidenbach, 1859, Hyperaspis peezi Fürsch, 1976, Hyperaspis pseudopustulata Mulsant, 1853, Nephus bisignatus (Fürsch, 1984), Rhyzobius forestieri (Mulsant, 1853), Scymniscus anomus (Mulsant & Rey, 1852) and Scymnus doriae Capra, 1924 are recorded for the first time in Switzerland. In parallel, Chilocorus similis (P. Rossi, 1790), Bulaea lichatschovii (Hummel, 1827), Ceratomegilla rufocincta rufocincta (Mulsant, 1850), Coccinella undecimpunctata undecimpunctata Linnaeus, 1758, Chnootriba elaterii (P. Rossi, 1794), Henosepilachna vigintioctopunctata (Fabricius, 1775), Hyperaspis quadrimaculata (Redtenbacher, 1843), Scymnus marginalis (P. Rossi, 1794) and Novius cardinalis (Mulsant, 1850) were recorded from Switzerland in the past but are excluded from this list, either due to insufficient documentation or because they represent isolated cases of introductions of non-indigenous species that never became established in Switzerland
