A new species of Eocene fossil Malthodes (Coleoptera: Cantharidae) with a rarely observed aedeagus.

A new Malthodes (Coleoptera, Cantharidae, Malthininae) in Eocene amber from Poland (Baltic amber) is illustrated and described here: Malthodes (s. str.) maximiliani sp. nov. The new species of soldier beetle is characterized by its small body size and last tergites and last sternite distinct from similar taxa. Notably, the specimen has a partially visible aedeagus, a characteristic rarely seen in fossil Malthodes of the nominotypical subgenus; it has been observed in only three fossil species of this subgenus.

A new genus and species of Encyrtidae (Hymenoptera: Chalcidoidea) with a four-segmented funicle from late Eocene Baltic amber.

Electrocerus brevifuniculatus Simutnik gen.etsp. nov. is described and illustrated based on a female specimen from late Eocene Baltic amber. Placement of the new genus in the subfamily Encyrtinae is supported by the presence of a filum spinosum on the linea calva and the hypopygium not reaching the metasomal apex. A key to the genera of late Eocene Encyrtinae is provided. The new taxon differs from all known extinct and most extant encyrtids by its four-segmented female funicle.
