Text-figure 5. Drawing of specimen (hind wing) of Blattelytridae 
from Obora, Moravia (Lower Permian), no. 6/1965, Department of Palae- 
ontology, Charles University, Prague. Lettering as in text-figure 1. 
R, then anastomosing with Rs; M2 diverges posteriorly abruptly 
after its origin and anastomoses with CuA, which is directed 
anteriorly away from the stem of Cu ; these two veins, together 
with their fused portions, form a very distinct “Y” vein, which 
terminates on CuP well before the apex; Cu arising as an inde- 
pendent vein from the base; iA also arising from the base, close to 
CuP, and continuing parallel to it and very close to it for its entire 
length to the apex of the wing; a series of radiating anal veins 
extends from iA, forming the anal fan. As shown in text-figure 3, 
the remigia of the right and left sides are slightly different in shape; 
the hind wing on the right probably has more distortion than that 
on the left, as indicated by the presence of some of the anal veins 
across the tip of the remigium. 
The body structure of this specimen of Parablattelytron is only 
moderately well preserved; the abdomen is suggested by an outline 
in the matrix, although the terminal segments, with a pair of cerci 
(length, 1.2 mm.), are distinct; the distance from the point of 
attachment of the elytra to the end of the abdomen is about the length 
of the elytra, indicating that the abdomen as a whole was covered 
by the elytra when they were folded back over the body. The pro- 
notum is much broader than long, with a slightly concave anterior 
margin. The thoracic nota are irregularly rough in appearance and 
seem to bear short, truncate tubercles. Only the femora of the front 
and middle legs are preserved, these bearing short setae. The head 
is only vaguely indicated but it is distinctly smaller and narrower 
than in Protelytron and Apachelytron. One antenna, clearly pre- 
served, is 4 mm. long, relatively broad at the base but tapering 
abruptly; about 17 segments are visible but there were probably
