The ladybird beetles (Coccinellidae) of South Dakota

An updated list of 79 species of Coccinellidae for South Dakota is presented. Twelve species have been added to the list as new state records: Didion punctatum (Melsheimer), Didion nanum (LeConte), Scymnus paracanus linearis Gordon, Scymnus fraternus LeConte, Hyperaspis inflexa Casey, Hyperaspis troglodytes Mulsant, Hyperaspis brunnescens Dobzhansky, Hyperaspis quadrivittata LeConte, Brachiacantha decempustulata (Melsheimer), Brumoides septentrionis septentrionis (Weise), Hippodamia expurgata Casey, and Hippodamia sinuata crotchi Casey. Eight other species were added after reviewing previously published species records and faunal distribution maps. Several entries were deleted from the list based on synonymies. Three others were deleted because of dubious collection records, and one because of misidentification.
