An annotated checklist of Tetranychidae (Acari: Trombidiformes) of the Transcarpathian region (Ukraine)

Abstract

The first checklist of spider mites (Tetranychidae) of Transcarpathia, Ukraine is compiled based on the revision of collection materials stored in I. I. Schmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine. The mite collections of I. Akimov, A. Putrashik, and of the authors were studied, thus covering a 45 year-long period of research of spider mites in the study region. The checklist includes 28 species of 10 genera of tetranychid mites, which is about 40% of the species diversity of spider mites in Ukraine. For each species, information is provided on the number of individuals (males, females, nymphs, and larvae), host plants, record localities (for own collections—with geographic coordinates), as well as data on distribution in other regions of Ukraine. The largest part of the collection includes the findings of common species, such as Amphitetranychus viennennsis, Bryobia rubrioculus, and Panonychus ulmi. The genus Eotetranychus is represented by the largest number of species (8). Two species (Eotetranychus quercicola Auger & Migeon, 2014 and Schizotetranychus beckeri Wainstein, 1958) are recorded for the first time for the fauna of Ukraine. In addition, 21 species of spider mites are noted for the first time for the territory of Transcarpathia. Three of the 11 species previously indicated for Transcarpathia, namely Oligonychus brevipilosus Zacher, 1932, Oligonychus lagodechii Liv. et Mitr., 1969, and Schizotetranychus jachontovi Reck, 1953 are not represented among the collection materials. In addition to the two taxa noted here for the first time in Ukraine, five species of tetranychids (Bryobia praetiosa, Bryobia lagodechiana, Eurytetranychus furcisetus, Schizotetranychus spireafolia, and Tetranychus frater), which were previously discovered in other regions of Ukraine, should be included in the electronic database of Spider Mites Web as those recorded in Ukraine. Eight host plant species are indicated for the first time for six spider mite species (Eupatorium cannabinum for B. praetiosa, Armoracia rusticana, Betonica officinalis, and Melilotus officinalis for B. lagodechiana, Picea abies for E. furcisetus, Ribes nigrum for A. viennensis, Quercus robur for E. quercicola, and Salix glauca for S. shizopus).
