Three new species of Coccidae: Cryptinglisia chilensis Kondo & Gullan sp. nov., Pulvinaria drimyswinteri Kondo & Gullan sp. nov., and Stictolecanium cranstoni Kondo & Gullan sp. nov., are described and illustrated. An updated species list and a taxonomic key to the 13 coccid species now known to occur in Chile are provided. Pulvinariella mesembryanthemi (Vallot) is newly recorded for Chile. Lecanium resinatum Kieffer & Herbst, currently known as Coccus resinatus (Kieffer & Herbst), is transferred to the family Kerriidae as Tachardiella resinata (Kieffer & Herbst) comb. nov., based on examination of the original German description.
