Abstract

Until now, the genus was represented by two extant species: Matile & Vockeroth, 1980 from North America and (Okada, 1939) from Asia. This paper presents the first fossil members of the genus , which is also the first record from Europe. Two new fossil species from Baltic amber are described: PeÅ‚czyÅ„ska, KrzemiÅ„ski & Blagoderov, sp. nov. and PeÅ‚czyÅ„ska, KrzemiÅ„ski & Blagoderov, sp. nov.. The presence of fossil spp. on the European continent suggests Holarctic distribution of the genus in the past. We also discuss possible pathways of its intercontinental dispersion.
