ABSTRACT A new orsodacnid leaf beetle, Aulacoscelis (Cretaulacoscelis) santanensis n. subgen. et n. sp. of the subfamily Aulacoscelidinae of the family Orsodacnidae, is described from the Aptian-Albian Santana Formation of the Lower Cretaceous. The new subgenus differs from the subgenus Aulacoscelis s. str. in the elytra having distinct striae, the large eyes and a narrow-triangular scutellum. This is the first record of a fossil Orsodacnidae and the first Chrysomeloidea described from the… 
A new species of the genus Orsodacne Latreille, 1802 (Coleoptera: Orsodacnidae) from China
A new species, Orsodacne yunnanicus Legalov, sp. nov. from Yunnan Province (China) is described and illustrated. The new species is similar to Orsodacne cerasi (Linnaeus, 1758) but differs from it in


New records and species of Crepidodera Chevrolat (Coleoptera: Chrysomelidae) in Eocene European amber, with a brief review of described fossil beetles from Bitterfeld amber.
Based on six relatively well-preserved specimens from Eocene Baltic amber, Crepidodera tertiotertiaria sp. nov. is described. The new species is illustrated and compared with morphologically similar

The diverse fossil Lamprosomatinae representatives provide strong evidence for the presence of thermophilic, humid and mixed forest, and indicative of warm temperate, humid, equable climate with reduced thermal seasonality in the Eocene Europe.
Fossil history of Mesozoic weevils (Coleoptera: Curculionoidea)
Changes of family, genera and species abundance during the Mesozoic revealed three distributional patterns and the change of weevil fauna during this period was due to the expansion of the angiosperms, which provided multiple niches in their vegetative and reproductive organs for weevil development.
Mesozoic leaf beetles of the tribe Mesolpinini trib. nov. (Coleoptera, Chrysomelidae) from the Lower Cretaceous
This publication is based on recent studies of Lower Cretaceous leaf beetles from the Yixian Formation (Liaoning, China), which are represented by five new species of one new genus Mesolpinus gen. nov. of the subfamily Chrysomelinae, which is the oldest known group of the family in the fossil record.
