widest beyond mid-wing, a smaller lobe on the posterior margin and 
long, S-shaped cross veins. 
Holotype: No. 5/1974 (fore wing fragment, length 11.4 mm, 
width 5.8 mm, obverse). Paleontological Institute of Charles Uni- 
versity, Prague, Czechoslovakia). 
Genus Diapha, new genus 
Type species: Diapha Candida n.sp., Lower Permian of Moravia. 
Fore wing: MA anastomosing with Rs for a short distance. 
Wings slightly broadened beyond mid-wing. Posterior margin con- 
cave. Sc terminating on R shortly beyond mid-wing. Rs with 5-6 
branches. Hind wing shorter and probably narrower, with anal 
veins less branched. Diapha differs from the other genera described 
herein by the shape of the wings. 
Diapha Candida n.sp. 
Figure 6, 7 
A detached fore wing and a hind wing are referred to this species. 
The hind wing differs slightly in the outline of the posterior margin 
and in the thinner membrane. It may belong to a different species. 
Fore wing: length 19 mm, width 5 mm. Wing broader in the 
distal half. C basally with a series of more prominent setae. Stem 
of R distinctly swollen next and distally from the basal fold. Rs 
concavely bent in the apical part, with 6 branches. MA simple, 
MP forked. CuA simple, CuP simple or with a branch. iA with 
several branches, anal veins sometimes branched. 
Hind wing: length 14 mm, with 4.2 mm. Wing membrane very 
thin. 
Holotype: No. 6/1974 (fore wing, length 18.7 mm, width 5 mm, 
obverse); specimen No. 7/1974 (hind wing, length 14 mm, width 
4.2 mm, obverse and reverse). Paleontological Institute of Charles 
University, Prague, Czechoslovakia. 
Genus Permodiapha, new genus 
Type species: Per?nodiapha carpenteri n.sp., Lower Permian of 
Moravia. 
Fore wing: MA touching Rs or anastomosing with Rs for a 
short distance. Wing very broad. Posterior margin evenly con- 
cave. Sc terminating on R shortly beyond mid-wing. Rs with 3-4 
branches. Hind wing similar to fore wing, but broader.
