Figure 9. Monsteropterum moravicum n.sp. Enlarged ovipositor with 
striations, scattered setae and stylus (S), resembling the endophytic ovi- 
positor of Odonata. Lower Permian of Czechoslovakia. 
The legs expose their natural ventral surface. The coxae are short 
and conically truncate (fig. 6-C; fig. io-'C). Proximally are ad- 
joined two additional circular structures, which perhaps represent the 
katapleuran ring separated by a sigmoidal paracostal suture from the 
anapleuran ring (fig. 10-K, S, A). The trochanter (fig. 6-T ; fig. 10- 
T) is grown together with the femur and is preserved only as a 
triangular swelling. The tibia is slightly longer than the femur. The 
tarsus is five-segmented, with the 3rd and 4th segments distinctly 
shorter than the remaining ones. The praetarsus bears a pair of lat- 
eral claws. The legs are covered by scattered setae and a granular 
rugosity. 
The mesothorax and metathorax are about equal in size, with a 
broad V-shaped ridge. 
The ovipositor has striations (fig. 9) similar to those in some other 
Palaeodictyoptera (Kukalova in Carpenter, 1971, p. 1241, fig. 6) 
and in the related order Diaphanopterodea (Kukalova 1961, p. 293, 
fig. 2). The ovipositor carries scattered, proximally oriented, setae. 
With this specimen styli are recognized for the first time for the 
order Palaeodictyoptera. Within the extant insects, styli on female 
genitalia are known in the adult stage only in one order, the Odo- 
nata, in which they arise from the second coxopodite. Also, the gen- 
eral appearance of the ovipositor is very much like the endophytic 
ovipositors of some Odonata. 
The projections (fig. 6-P) are long and very branched, apparently 
much more than preserved in the fossil. They have scattered setae 
and their surface is finely rugose. The sockets of the setae are deeply 
incised and their density is about equal to that on the legs. The setae 
increase in number towards the ends of the branches. The projections 
are stiffly backwardly curved and were undoubtedly sclerotized. 
Previously, I have been able to study projections in four families 
of the order Megasecoptera. In all the projections were simple, un-
