Stenodiapha angusta n.sp. 
Figures 15, 16, 17, 18 
Three detached fore wings and one hind wing are referred to 
this species. 
Fore wing: length 17.2-20 mm, width 3. 8-4. 3 mm. Wing broadest 
at mid-wing, narrowing proximally. Wing membrane very thin. Rs 
with 4 long branches. MA simple, MP simple; CuA simple, CuP 
simple or forked. Anal veins with few branches or simple. Hind 
wing: length about 16.5 mm, width 4.4 mm. Similar to the fore 
wing, but shorter. In hind wing No. 20/1974, the richly branched 
MP is reminiscent of the Carboniferous genus Diaphanoptera. 
Holotype: No. 17/1974 (fore wing fragment, length 18.2 mm, 
width 4.3 mm, obverse); specimen No. 18/1974 (fore wing frag- 
ment, length 15.7 mm, width 3.8 mm, obverse and reverse) ; specimen 
No. 19/1974 (fore wing fragment, length 14.6 mm, width 3.8 mm, 
obverse and reverse); specimen No. 20/1974 (hind wing fragment, 
length 15 mm, width 4.4 mm, obverse and reverse). Paleontological

Stenodiapha moravica n.sp. 
Figure 19, 20 
This species is based on two detached wings, probably fore wings. 
Fore wing: length about 20.7 mm, width 5.3 mm. Wing broad- 
ened slightly at mid-wing. C serrated, basally carrying a series of 
setae. R sending off anteriorly several long twigs beyond the end 
of Sc. Rs with 3 long branches. MA simple, MP forked. CuA 
and CuP forked. Anal veins with few branches or simple. 
Stenodiapha moravica differs from angusta in having the wings 
broader in the basal third and in the presence of long twigs on 
R beyond the end of Sc. 
Holotype: No. 21/1974 (fore wing fragment, length 19.2 mm, 
width 5.3 mm, obverse and reverse); specimen No. 22/1974 (fore 
wing fragment, length 11.5 mm, width 5.3 mm, obverse). Paleonto- 
logical Institute of Charles University, Prague, Czechoslovakia. 
Paradiapha, new genus 
Type species: Paradiapha delicatula n.sp., Lower Permian of 
Moravia. 
Fore wing: MA joining Rs for a short distance. Wing broadest 
at about the end of the second third, narrowing abruptly at the 
base. C serrated. Sc terminating on R shortly beyond mid-wing.
