| Abstract: | A fossil trigonalid (Trigonalidae: Hymenoptera), Eotrigonalis balticus Poinar, n. gen., n. sp., and a fossil vespid, Palaeovespa socialis Poinar. n. sp., are described from Eocene Baltic amber. Eotrigonalis balticus is a large. robust. heavily armored species, which could have parasitized members of the Vespidae. It can be separated from ail other members of the family by the presence of large scutellar horns. Palaeovespa socialis has the diagnostic characters of members of the subfamily Vespinae and was probably eusocial. It differs from extant vespines by the shape of the clypeus, the presence of interparapsidal furrows and venational characters. |
