Abstract—A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov.
from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the
Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis,
sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolu-
tion, as well as the possible ecology and bionomics of their members are discussed. It is shown that "Phenolia"
incapax
Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.

Key words: Eocene amber, beetles, Nitidulini, new taxa.
