^ 1. Family Trachopterygidae, new family 
Small insects. Fore wing: coriaceous; veins thick, the membrane 
very rough or rugose. Costa marginal, unusually thick, extending 
to apex of wing; the rest of the wing margin also thick, but less 
so; venation reduced, with all veins (except SC and possibly 1A) 
arising from a main stem-vein and extending in almost straight 
lines diagonally across the wing. Cross veins absent on most of 
the wing. Numerous fine setal bases on the costa and most other 
veins. 
Trachopteryx, new genus 
Fore wing: SC short, crowded between the costa and the stem- 
vein and terminating at about the level of the origin of MA. The 
other seven main veins (as interpreted below) are long but without 
branches. 
Type-species: Trachopteryx martvnovi , n.sp. 
The generic name is derived from the classical Greek words 
trachys (rough) and pteryx (wing) and is considered feminine and 
singular. 
Trachopteryx martynovi, n.sp. 
Figures 12 and 13 
Fore wing: length, 1 1 mm; width, 5 mm. RS arising about 2/3 
the wing length from the base; R1 with 4 short cross veins leading 
SC
