Abstract: | A micropterous female embolemid is recorded in middle Eocene Baltic amber. Embolemus excitus Perrichot and Engel, sp. nov., is easily distinguished from other extinct and living species by the pronotum with only a weak mediolongitudinal furrow and with a lateral carina along the edge anterior to tegula, the mesopleuron with a pronounced medial dorsoventral carina, and the propodeum with dorsoposterior corners tuberculate. The new species also uniquely combines greatly reduced compound eyes, a scape distinctly elongate, the pronotum twice as long as mesoscutum, and the forewings extending at most to the anterior border of the second metasomal tergum. |
