Catalogus

        The high diversity and evenness of weevil assemblages is shown by species sequence curve analysis in the Crimean Mountains, the Carpathians, steppes and lowland broad leaf forests, which contrasts with assemblages in lowland mixed forests. Shannon-Wiener and Simpson indices both show an extremely broad range of evenness in the Pontic Steppes which have both assemblages with low evenness in Stipa-Festuca-Koeleria steppes and high evenness in Stipa-Bromopsis steppes (H' =1.87–4.22). East European Forest Steppe and Central European Mixed Forests harbour similarly even communities (H' =3.60–4.48 vs. 3.18–4.57). The Crimean Mountains and the Carpathians are defined as a hotspot of biodiversity combining the highest scores of endemics, R1 species, and highest alpha diversity. Host plants are documented for 1259 species. Some 83% of weevils feed on live tissues of angiosperm plants belonging to 64 families. A total of 258 species are confirmed as polyphagous, 8 as monophagous, thus the majority of the rest are more or less narrowly oligophagous. A total of 33.68% of the species are associated with Fabaceae, Asteraceae, and Brassicaceae.
