Abstract
A new genus Plesiomedetera gen. nov., is described from Late Eocene Baltic amber. The genus is placed in the extant subfamily Medeterinae and includes five recognized and two doubtful species, all poorly described by Meunier in 1907–1908 and never reported again. Plesiomedetera flammea (Meunier, 1907), comb. nov. and P. mustela (Meunier, 1907), comb. nov. are described and illustrated, and a key to recognized species of this genus is compiled. The other eight extinct genera from Baltic amber are briefly reviewed, belonging to extant subfamilies ?Diaphorinae, Dolichopodinae, Medeterinae, Peloropeodinae and Sciapodinae, and a key to these genera is compiled. The following new combinations (comb. nov.) are proposed: Plesiomedetera decora (Meunier, 1907), P. elegantula (Meunier, 1907), P. vana (Meunier, 1907), P. lasciva (Meunier, 1907), P. lepida (Meunier, 1907), Medeterites atterraneus (Nazarov, 1994), M. gestuosus (Meunier, 1907), M. gulosus (Meunier, 1907), M. latipennis (Meunier, 1907), Palaeoargyra planipedia (Meunier, 1907), Palaeomedeterus praeconcinnus (Evenhuis, 1994), P. concinnus (Meunier, 1907), P. tertiarius (Meunier, 1907), Prohercostomus ciliatus (Meunier, 1907), P. devinctus (Meunier, 1907), P. gracilis (Meunier, 1907), P. minutus (Meunier, 1907), P. morbosus (Meunier, 1907), P. smicrus (Meuffels et Grootaert, 1999) and P. inumbratus (Meunier, 1907). Sciara pusilla Meunier, 1899 is considered nomen nudum, rather than unplaced species of Dolichopodidae. Dolichopus smicrus Meuffels et Grootaert, 1999 (unnecessary new name) is placed in synonymy with Prohercostomus minutus. In all, 53 recognized, 5 doubtful and 10 unplaced species from Baltic amber are listed.
