Genus Moravohymen new genus 
Type species: Moravohymen vitreus n.sp., Lower Permian of Moravia, 
Wings rather small, narrow in the proximal half, broad in the 
distal half; C not flattened; Sc rather a thin vein; Ri sending off 
several short twigs apically; Rs originating shortly behind midwing; 
Rs with 3 branches; branches of M and Cu simple; Ai remote from 
the posterior margin, anal branches irregular and rather long; cross 
veins arranged by two or three in the posterior part of the wing. 
Species included: Moravohymen vitreus n.sp. (Lower Permian of 
Obora, Moravia). 
Moravohymen vitreus n.sp. 
Figure 5 
This species is based upon an obverse and reverse of a wing with 
damaged proximal part. According to the concave shape of the pos- 
terior margin it might be a hind wing. 
Wing fragment: length 21 mm, maximum width 6.9 mm; C, Sc 
and Ri distally much thinner veins than in Bardohymenidae ; the 
membrane in the pterostigmal region probably sclerotized; Ri send- 
ing off 3 terminal twigs to C; ri-rs area broad, with 6 weak cross 
veins; Rs branches occupying a considerably large area; cross vein 
connecting MA with R at the origin of Rs is a heavy bar, thickened 
at its costal end; cross veins in medial area and cubital area slightly 
sigmoidal; posterior margin with small convex bends in between the 
ends of median and cubital branches. 
Holotype: No. 4/1972 (obverse and reverse probably of hind 
wing) ; Paleontological Institute of Charles University, Prague,
