NEW LATE EOCENE CHRYSOMELIDAE (INSECTA: COLEOPTERA) FROM BALTIC, ROVNO AND DANISH AMBERS

New fossil taxa of Chrysomelidae are described: from Baltic amber, Succinispa stainesi Nadein gen. et. sp. nov. (Cassidinae: Oposispini); from Danish (Scandinavian) amber, Psyllototus viking Nadein sp. nov. (Galerucinae: Alticini), Calomicroides danicus Nadein gen. et sp. nov. (Galerucinae: Galerucini: Luperina), Paleomolpus hirtus Nadein gen. et sp. nov. (Eumolpinae: Eumolpini); from Rovno amber (Ukraine, Klesov), Archealtica convexa Nadein gen. et sp. nov. (Galerucinae: Alticini), Taphioporus rovnoi Moseyko and Perkovsky sp. nov. (Eumolpinae: Euryopini). Leaf beetles in succinites are represented by four species of extant 'Holarctic' (temperate) genera in contrast to one species of a Recent ` tropical' genus. Faunal composition of leaf beetles of late Eocene succinites supports the opinion of Archibald and Farrell (2003) that arthropods with different climatic preferences preserved in Baltic amber were able to co-exist under an extinct equable climate with temperate summers and mild winters.
