Archsolva , new genus

DIAGNOSIS: Wing broad, W/L 0.46–0.50; fork of R 4 -R 5 short, nearly symmetrical; vein C ends slightly past apex of R 5 (vs. at apex of M 1); cell m short, with long vein M 3 +CuA 1; tergite 1 with anterior portion membranous; tergites 1–5 with deeply impressed transverse sulci; metafemur lacking ventral denticles.

TYPE SPECIES: Archosolva biceps , new species.

ETYMOLOGY: From archaios (Greek, “old”) (in reference to the age) and the genus Solva , to which the fossil appears related. The gender of the name is feminine.

COMMENTS: Based on the short, triangular abdomen, with a thick base and narrow apex, and the membranous anterior portion of tergite one, this genus appears related to Arthropeina and Solva . However, in the fossil genus vein C ends at the apex of R 5 (vs. M 1), and it (plesiomorphically?) has deeply impressed transverse sulci.
