Abstract:
Libanissus bkassinensis Azar, Maksoud & Nel, gen. et sp. nov. is illustrated and described from the Lower Cretaceous dysodile (oil papershales) of Bkassine, South Lebanon, and its taxonomic position discussed. Libanissus bkassinensis Azar, Maksoud & Nel, gen. et sp. nov. is characterized by its banded legs and body, a hind wing with two lobes, RA and RP very short, M with only two very short apical branches, CuA with two branches, and a small but distinct apical furcation of PCu close to the incision of the wing margin. Libanissus bkassinensis Azar, Maksoud & Nel, gen. et sp. nov. represents the earliest record (lower Barremian) of the Issidae. Prior to this discovery, the oldest known record was from the Paleocene of France.
