Blankaartia acuscutellaris (Walch, 1922) (Actinotrichida: Trombiculidae) collected from the great snipe Gallinago media (Latham, 1787) (Charadriformes: Scolopacidae) in Poland – new host and country record for chigger mite genus and species

The parasitic chigger mite, Blankaartia acuscutellaris, collected from a female of Gallinago media is recorded from Poland for the first time. The locality, which constitutes the northernmost record of B. acuscutellaris in the Palaearctic, raises the question of possibility of establishing a new population on the verges of the species’ distribution range. Metric data for larvae, extending the knowledge of intra-specific variation, are provided.
