Anconeura, new genus 
Wings: very long and narrow; posterior margin undulated beyond 
mid-wing. R 1 close to the costal margin; Rs with about 4 long 
branches, sometimes forked ; MA with a series of short branches ; 
MP with a long, branched fork; CuA forked. Cross veins irregular. 
Anconeura differs from Arcioneura by its larger wings, which have 
more numerous branches on Rs and CuA. The generic name is 
derived from the Greek words ankos and neura (curve + veins) 
and is considered neuter plural. 
Type species: Anconeura havlatai, n.sp.

Figure 9 
This species is monotypic, based upon an adult wing with a well 
preserved, long, petiolate base. Distally from mid-wing, the wing is 
broken into several dislocated pieces. In figure 8, the venation is 
shown restored to its normal pattern. 
Wing: length about 41 mm, width 5.7 mm. Wing broadest 
shortly beyond mid-wing ; posterior margin with 4 undulations ; at its 
proximal end the petiole broadens for its attachment to the thorax. 
Rs originating at about the end of the basal third, the first branch 
of Rs starting before mid-wing; MA sending off 3 branches; MP 
probably branched 4 times; CuA probably branched 5 times; CuP 
with 1 branch. iA close and parallel with the posterior margin, with 
one branch. 
Holotype: no. 23/1974 (almost complete wing, length 40 mm, 
width 5.7 mm; obverse). Paleontological Institute of Charles Uni- 
versity, Prague. 
The species is named for Karel Havlata of Prague, who has col- 
lected hundreds of specimens of insects in the Obora beds. 
Family Ancopteridae, new family 
Wings: elongate; almost equally broad beyond mid-wing; posterior 
margin undulated. Sc somewhat shortened; stems of R and M not 
coalesced in the basal third ; Rs diverging from R 1 much before mid- 
wing; MA and CuA simple, MP and CuP branched. Cross veins 
numerous, forming conspicuous intercalated sectors. 
The family Ancopteridae differs from the related family Dictyo- 
neurellidae (Westphalian, France), and Anchineuridae (U. Car- 
boniferous, Spain) in the presence of the undulated posterior margin,
