[March 
Family Gaulopteridae, new Family 
Nymphal wing: petiolate, broadened beyond mid-wing, narrowed 
in the apical third; posterior margin undulated. Sc long; stems of 
R and M not coalesced in the basal third; Rs diverging from R 1 
before mid- wing; MA and MP branched; MP anastomosed with 
CuA for a short distance; CuA simple, CuP sending off several 
branches; iA with a series of branches. Cross veins numerous, Mr- 
regular, forming intercalated sectors.. 
This family differs from the Anchineuridae in the petiolation of 
the wing, the branched MA and the coalesced MP and CuA. 
Although the shape of the wing in the family Caulopteridae and 
in the following three families is specialized and typical for Mega- 
secoptera, the venation is reminiscent of that in the Palaeodictyoptera. 
If the proximal, narrow part of the wing has not been preserved, the 
megasecopterous character of such a fragment would be obscure. 
This seems to be true for several incompletely preserved wings pre- 
viously considered palaeodictyopterous, discussed below. 
At present this family includes only the following genus: 
Gauloptera, new genus 
Nymphal wing: moderately slender, with a broad lobe in the third 
quarter of the wing length ; posterior margin undulated beyond mid- 
wing only within the mp area. Sc, R 1 and Rs equally distant from 
each other, close to, but not crowded towards the costal margin; 
Rs with 2 long branches; MA with several short branches. 
The generic name is derived from the Greek words kaulos and 
ptera (petiole + wings) and is considered neuter plural. 
Type species: Cauloptera colorata, n.sp. 
Gauloptera colorata, n.sp. 
Figure i 
This species is based on a detached, well-preserved wing pad of a 
late nymph; the base is narrowed, perhaps petiolate; the basal third 
is missing. 
Nymphal wing: length (estimated) about 41 mm, width 9 mm. 
Broadened part of the wing forming a smooth, broad lobe; undula- 
tions in the mp area shallow; apex comparatively broad and rounded.
