Terrestrial Parasitengona mites (Trombidiformes) of Denmark – new data on parasite-host associations and new country records

Abstract

An updated list of terrestrial Parasitengona mites of Denmark, containing 34 species aggregated in eight families, is presented and compared to existing records from Fennoscandia. Five parasitengone species, Charletonia cardinalis, Leptus mariae (Erythraeidae), Platytrombidium fasciatum (Microtrombidiidae), Paratrombium egregium (Trombidiidae) and Centrothrombidium blackwellae (Johnstonianidae) are recorded as new to the fauna of Denmark. We provide 29 records of parasite-host association between terrestrial Parasitengona mites and their arthropod hosts. Of those, 15 associations are recorded for the first time.
