Genus Protodiapha, new genus 
Type species: Protodiapha maculifera n.sp., Lower Permian of 
Moravia. 
Fore wing: MA and Rs connected with a very short cross vein. 
Wings short and broad, broadest at about mid-wing. Posterior 
margin convexly bent, forming a lobe. Sc terminating on R shortly 
beyond mid-wing. Rs area small, with about 5 branches. Hind wing 
similar, but shorter, with the lobe on the posterior margin probably 
more pronounced. 
Protodiapha differs from all the other genera which lack the 
anastomosis between MA and Rs by the presence of the lobe on the 
posterior margin. 
Protodiapha maculifera n.sp. 
Figure 3, 4 
This species is established upon hind wings having a prominent 
lobe on the posterior margin and circular, cuticular spots on the 
wing membrane. 
Hind wing: length 14 mm, width 4.5-5 mm. Wing broadest 
before the level of the end of Sc. The lobe on the posterior margin 
extending to the end of CuP. C with a series of long setae. Rs 
almost straight, with 5 branches. MA simple, MP with a fork. 
CuA simple, CuP sometimes with short branches. Anal veins with 
few branches. Thickened cuticular spots present. 
Holotype: No. 3/1974 (hind wing, length 13.5 mm, width 4.5 
mm, obverse); specimen No. 4/1974 (hind wing fragment, length 
8.3 mm, width 5 mm, obverse). Paleontological Institute of Charles 
University, Prague, Czechoslovakia. 
Protodiapha lineata n.sp. 
Figure 5 
This species is monotypic and based on the proximal half of a 
fore wing. However, the unique S-shaped cross veins accompanied 
by dark spots separate the species distinctly from all other Elmoidae. 
Fore wing: length of the fragment 11.4 mm, width 5.8 mm. 
Wing broadest beyond the level of the end of Sc. The small lobe 
on the posterior margin extending to the end of CuP. Veins darkly 
colored. CuA with a short branch, CuP simple. Anal veins with 
few branches. Cross veins long, S-shaped, surrounded by dark 
spots. Circular cuticular spots absent.
