021387DAFF85FFD1FF7E09B941E0604D.taxon	diagnosis	Diagnosis. Female characters only. Closest to Teredon (see discussion), but easily separated from Teredon females by any of the following: broad metathoracic femur, much broader than tibia; forewing character states: cell 1 R width about a third length [about a fifth]; cell 3 R 1 distinctly closed (R 1 joins Rs) [open]; 1 r-rs distinct [very short or R 1, Rs meet at pterostigma]; Rs and M only touch without distinct Rs + M [distinct Rs + M].	en	Archibald, S.
