RESUMO
A new subgenus, Palaeoronia subgen. nov., is described from the Cretaceous amber of North Myanmar (Kachin State) and assigned to the genus Phenolia. The type species of the new subgenus, Phenolia (Palaeoronia) haoranae subgen. et sp. nov., is characterized by a rather 'archaic' aspect. A discussion of the diagnostic and structure of the Soronia-complex of genera (together with the Phenolia-complex of genera) (Nitidulinae, Nitidulini) is proposed. Reasons for the 'conservatism' of this group during the Mesozoic and Cenozoic are discussed. The position of the Apophisandridae stat. nov. (type genus Apophisandra) and the transfers of the following genera into this family: Cretaretes, Electrumeretes, Furcalabratum, Pelretes, Polliniretes, Protokateretes, Protonitidula, and Scaporetes, from the Kateretidae, Nitidulidae or Cerambycidae are grounded. The relations of the family Parandrexidae (with inclusion of the genus Cretoparacucujus, transferred from Boganiidae with a proposal of the subfamily Cretoparacucujinae subfam.nov.), Martynoposis and Parandrexis are considered. The genus Antirhelus gen. nov. (type species Heterhelus buzina) is assigned to the new subfamily, Antirhelinae subfam. nov. in the family Kateretidae. The fossil records of the 'nitidulid' group of families (Apophisandridae stat. nov., Kateretidae, Nitidulidae, Parandrexidae, Smicripidae and possibly Boganiidae) are reviewed. The relationship of the family Boganiidae, some aspects of pollination and pollinophagy, and also changes in beetle diet in the past are discussed. The lectotype of Parandrixis parvula is designated.
