Permodiapha specula n.sp. 
Figure 13 
This species is monotypic and based upon a fore wing. 
Fore wing: length 13.3 mm, width 4.8 mm. Wing relatively 
small, with very thin wing membrane. Cross veins almost invisible. 
Proximal half of the wing much narrower than the distal half. 
Venation very simple, seldomly branched. MA only touching Rs 
at a point. Rs sending off 4 branches, Rs S-shaped distally. MA, 
MP, CuA and CuP simple. Anal veins mostly simple. Circular 
cuticular spots present. 
Permodiapha specula differs from carpenteri and lata in having 
the smallest wings with the most simple venation; in having the 
wings narrowed in the proximal half; and in the presence of the 
circular cuticular spots.

Permodiapha sp. specimen No. 14/1974. (fig. 14) (hind wing 
fragment, length 11 mm, width 4.5 mm, obverse and reverse) might 
represent a separate species within the genus Permodiapha , but the 
fragment does not provide enough features for specific diagnosis. 
Genus Stenodiapha, new genus 
Type species: Stenodiapha angusta n.sp., Lower Permian of 
Moravia. 
Fore wing: MA anastomosed with Rs for a short distance. 
Wing narrow, elongate, with main veins obliquely oriented. Sc 
terminating on R shortly beyond mid-wing. Rs with 3-4 branches, 
rs area long and narrow. Hind wing similar to the fore wing, but 
shorter and broader. 
Stenodiapha differs from all other genera with MA-Rs anastomosed 
by the longest and narrowest wings, with the veins most obliquely 
oriented.
