Vulgarogamasus edurus sp. nov. (Acari: Parasitidae) is described based on females, deutonymphs and males extracted from leaf litter and soil in Ami, Ibaraki Prefecture, Japan. Morphological differences between the new species and its closely related species, Vulgarogamasus fujisanus (Ishikawa, 1972), are recorded based on the examination of type materials. Information about parasitid mites reported in Japanese literature is reviewed, and a key to species is provided.
