Lebanognoriste , new genus

DIAGNOSIS: Wing membrane without macrotrichia, R 1 short, crossvein r­m fused with base of M 3+4, fork of M 3+4 and CuA not sessile; preapical palpomere attached at the tip of antepreapical, inner mid and hind tibial spurs longer than outer ones.

3+4

TYPE SPECIES: Lebanognoriste prima , n.sp.

ETYMOLOGY: The name is a combination of Lebanon, source country of the amber, and the genus name Gnoriste . The name is feminine.

COMMENTS: Lebanognoriste together with Archaeognoriste form the most basal group of Lygistorrhinidae . Synapomorphies such as rather long fore coxae; short vein R 1; short, transverse RS1 section; reduced base of the M 1 and M 2 fork; and crossvein r­m shifted proximally and aligned to M2 + tb fused vein, which is oblique or longitudinal and shifted proximally, undoubtedly ally these two genera with the lygistorrhinids (see also Analyses). Both genera lack autapomorphies, and comparison to recent representatives of the family indicates various plesiomorphies.
