New extinct ant genus (Hymenoptera, Formicidae, Myrmicinae) from late Eocene Rovno amber

A new fossil myrmicine ant genus and species Lelejus venustus gen. et sp. nov. , are described from late Eocene Rovno amber (Priabonian, 33.9–37.8 Ma). This differs all extant extinct Myrmicinae genera known the European ambers in combination of morphological features, particular: 13-segmented antennae with a very short scape filiform funiculus; 3-segmented maxillary 2-segmented labial palps; well-developed mandibles dentate masticatory margin; scutum broad notauli; forewings closed cells 1+2r, 3r mcu, cell approximately same length as 1+2r; free vein M branches off RS at midlength between junction cross-vein 2r-rs m-cu; cu-a is located far base wing, so branch 1M+Cu much longer than 2M+Cu.
