In this study, we conducted a summer sampling of carabid beetles in eastern Australia to identify their associated parasitic mites. Here, we describe three new species of the genus Eutarsopolipus from under the elytra (forewings) of three native carabid species (Coleoptera: Carabidae): Eutarsopolipus paryavae n. sp. (pterostichi group) from Geoscaptus laevissimus Chaudoir; Eutarsopolipus pulcher n. sp. (leytei group) from Gnathaphanus pulcher (Dejean); and Eutarsopolipus chlaenii n. sp. (myzus group) from Chlaenius flaviguttatus Macleay. We further provide an identification key of the world species of pterostichi and leytei species groups as well as closely related species of the myzus group possessing similar characters including short cheliceral stylets. The significant diversity of Eutarsopolipus recovered here suggests that the current knowledge about Australian podapolipid mites (specially Eutarsopolipus) is still in its infancy and deserves further study.
Résumé
Dans cette étude, nous avons effectué un échantillonnage estival de carabes dans l’est de l’Australie pour identifier leurs acariens parasites associés. Nous décrivons trois nouvelles espèces du genre Eutarsopolipus sous les élytres (ailes antérieures) de trois espèces de carabes indigènes (Coleoptera : Carabidae) : Eutarsopolipus paryavae n. sp. (groupe pterostichi) de Geoscaptus laevissimus Chaudoir, Eutarsopolipus pulcher n. sp. (groupe leytei) de Gnathaphanus pulcher (Dejean) et Eutarsopolipus chlaenii n. sp. (groupe myzus) de Chlaenius flaviguttatus Macleay. Nous fournissons en outre une clé d’identification des espèces mondiales des groupes d’espèces pterostichi et leytei ainsi que des espèces étroitement apparentées du groupe myzus possédant des caractères similaires, y compris des stylets chélicéraux courts. La diversité importante des Eutarsopolipus collectés ici suggère que les connaissances actuelles sur les acariens podapolipidés australiens (en particulier Eutarsopolipus) en sont encore à leurs balbutiements et méritent une étude plus approfondie.
