Type-material for all larvae of species of Chyzeria Canestrini, 1897 (Prostigmata: Chyzerioidea: Chyzeriidae) was examined, diagnoses are presented and a key to species provided. The genus Chyzeria is divided in two species groups, onychia and hirsti, according to morphological and host preference differences. In addition, two new species of Chyzeria are described from specimens parasitising paropsine beetles (Coleoptera: Chrysomelidae): Chyzeria southcotti n. sp. from five species of Paropsini in northern New South Wales, and Chyzeria grandis n. sp. from Paropsisterna agricola (Chapuis) in Victoria and Trachymela sp. in Tasmania. The larvae of Chyzeria derricki Southcott, 1982 are reported from Anostostoma australasiae (Gray) (Orthoptera: Stenopelmatidae) in southeast Queensland, and larvae of Chyzeria flindersi Southcott, 1982 are reported from P. agricola from Tasmania.
