Carpenter (1947). A significant contribution to the morphology of 
the wings was published by Carpenter (1962). Until now, the 
family has been based only upon isolated, more or less fragmentary 
wings. 
The following introduces certain characteristics of body structures 
and some additional features of wing morphology, based upon 5 new 
specimens from the Lower Permian of Siberia and Czechoslovakia. 
Wings subequal in length and shape, strongly petiolate, similar in 
venation; C flattened and wide, very close to Sc; Sc distinguishable 
as a separate vein only in proximal part of the wing; Ri contiguous 
with C and Sc except in the very distal part of the wing; Ri with 
short terminal branches ; Rs originating at about midwing, giving rise 
to 2-3 branches; M very close to R basally, diverging away from R 
beyond the first quarter of the wing length; M dividing into MA 
and MP at variable level, but near to the origin of Rs; MA con- 
nected with Rs or R with a strong cross vein; Cu at the base fused 
with the stem of M ; CuA connected with the stem of M by a strong 
cross vein; 2 anal veins, Ai long with a pectinate series of branches; 
A2 very short and simple; cross veins not numerous, usually ar- 
ranged in 2 rows; veins and wing margin with rows of setal bases 
or sockets. 
Body structures: head small, short and broad, with large pro- 
jecting eyes; antennae long, composed of many cylindrical segments; 
maxillary palpi robust; prothorax trapezoidal; mesothorax and meta- 
thorax large in proportion to the rest of the body; legs of middle 
length, cursorial; abdomen relatively slender, tapering abruptly in 
the anterior part ; females with 1 1 visible segments and protruding 
ovipositor; projections forming rows on the posterior margin of 
thoracic and abdominal segments; parallel, transverse rows of projec- 
tions on abdominal terga and occasionally on thoracic segments ; larger 
projections located in pairs in the central parts of the body segments. 
The family Bardohymenidae is closely related by wing morphology 
to Protohymenidae (Carpenter, 1962), which turns out to be true 
also for the body. However, the wing venation is less advanced, 
possessing an MA which is not anastomosed with Rs, and a CuA 
free from M. Also the general form of the wings is less specialized, 
as the hind wings are almost equal to the fore wings, not reduced in 
length as in the Protohymenidae. The body in both families is much 
alike, possessing a large thorax and tapered abdomen. The bardohy- 
menid body is, in relation to the wings, more heavy. Through the 
courtesy of Dr. Carpenter I was able to study Protohymen readi 
Carpenter ( 1 933 ) » Protohymen elongatus Carpenter (1930) and
