Permodiapha differs from all other genera with MA-Rs anasto- 
mosed by its very broad wings. 
Permodiapha carpenteri n.sp. 3 
Figure 8, 9, 10 
A detached fore wing and a hind wing are referred to this 
species. The hind wing No. 8/1974 has been chosen as the holotype 
because of its well preserved base. The structure of the wing base 
are discussed above with the family characters. 
Fore wing: length about 16 mm, width 5.3 mm. Wing large, 
with relatively strong membrane, veins and cross veins. Apex prob- 
ably rounded as in the hind wing. Rs sending off 4 branches, 
slightly S-shaped distally. MA simple, MP with a long fork. 'CuA 
simple, CuP simple or forked. Anal veins with several branches. 
Fore wing about equally long but narrower than the hind wing. 
Hind wing: length 16.3 mm, width 6.8 mm. Similar to the 
fore wing but broader, and narrowing more towards the base. 
Holotype: No. 8/1974 (hind wing, length 16.3 mm, width 6.8 
mm, obverse and reverse) ; specimen No. 11/1974 (fore wing frag- 
ment, length 11 mm, width 5.3 mm, reverse). Paleontological 
Institute of Charles University, Prague, Czechoslovakia. 
Permodiapha lata n.sp. 
Figure 11, 12 
The species is represented by the holotype, probably a male, con- 
sisting of a vaguely preserved fore wing, well preserved hind wing 
and part of the abdomen, and by a detached wing, probably a fore 
wing. 
Fore wing: length about 12.6-15.5 mm, width 4.9-5. 2 mm. Wing 
membrane very delicate, cross veins almost invisible. Apical part 
of the wing somewhat narrower than in carpenteri. Rs curved 
posteriorly, sending off 4 branches. MA and CuA simple, MP and 
CuP with a long fork. Anal veins with few branches. Fore wing 
longer and narrower, with the apical part more pointed than the 
hind wing. Hind wing: length about 14.5 mm, width 6 mm. An- 
terior margin strongly curved towards the apex. 
Permodiapha lata differs from carpenteri in having a very thin 
membrane and narrower fore wings. 
3 This species is named for Dr. Frank M. Carpenter (Harvard Univer- 
sity), who has published extensively on the Diaphanopterodea.
