Hana filia, n.sp. 
Figures 3-6a 
This species is based upon beautifully preserved distal halves of 
the fore and hind wings, in normal positions (see reconstruction of 
the outlines, fig. 6a) . The hind wing is somewhat longer and broader 
at the end of the anal area than the fore wing. The venation is 
almost identical in the wings, though the first branch of Rs originates 
more markedly distally in the hind wing. In both wings, the costal 
margin is proximally broken away; in the fore wing, the posterior 
part of the wing is superimposed over R. Both wings are restored 
to the original widths in figure 3. 
Besides the holotype, a small fore wing fragment (specimen no. 
26/1974, fig. 4), and a hind wing fragment (specimen no 27/1974, 
fig- 5) were found, showing a coloration and a lobation of the pos- 
terior margin remarkably similar to that of the holotype. 
Wings: length of the fore wings about 84 mm, width 10.5 mm; 
length of the hind wing about 88 mm, width 12 mm. Posterior 
margin deeply incised at the end of all branches of CuP and at 
MP2 ; Rs originating before mid-wing, Rs branches originating in 
the distal quarter of the wing; MA and CuA simple; MP with 2 
branches, CuP probably with 1 short branch; archedictyon and cross 
veins strong, conspicuous. Wing membrane covered with numerous 
prominent tubercles and with extensive, irregularly outlined dark 
areas; hind wings darker than fore wings. 
Holotype: no. 25/1974 (fore wing fragment, length 45 mm, 
width 9 mm ; hind wing fragment, length 38 mm, width 1 1 mm ; 
obverse and reverse) ; specimen no. 26/1974 (fore wing fragment, 
length 33 mm, width 9.5 mm; obverse and reverse); specimen no. 
27/1974 (hind wing fragment, length 19 mm, width 8.4 mm; ob- 
verse and reverse). Paleontological Institute of Charles University, 
Prague, Czechoslovakia.
