Abstract

The species Electrotoma kopylovi sp. nov. is described by the larva (prepupa) from the Upper Eocene Baltic amber. It is the second find of the fossil of Electorotomidae family. The new species differs from the only previously known E. succini Rasnitsyn, 1977 in the closer placed antenna and stemma, less shortened clypeus, symmetrical labrum and a richer head and thorax chetotaxy. The composition of E. kopylovi syninclusions proves the previously stated hypothesis suggesting a combination of some non-standard circumstances that caused electrotomids to get into the resin.
