phlebia are so marked that family separation of these genera seems 
unwarranted. 
A related genus, Turanothemis (see figure 2), has recently been 
described by Pritykina from the Jurassic of Karatau (Kazakhstan) 
in the Soviet Union and has been assigned to a separate family, 
Turanothemistidae (Pritykina, 1968). In her account of this 
family, the author makes no comparisons with any other specific 
family, simply stating that it differs sharply from all other families 
of this series of Anisozygoptera by the presence of only the two 
primary antenodals in the costal area and by the form of the dis- 
coidal cell in the hind wings. However, in Liasso phlebia, as already 
noted, only the two primary antenodals have been reported (Tillyard, 
1925) and its discoidal cell (hind wing) has precisely the same form 
as that of the fossil on which Turanothemis is based. Since no other 
distinguishing characteristics of the Turanothemistidae are dis- 
cernible, I consider the family Turanothemistidae inseparable from 
the Liassophlebiidae, which, on this basis, is known from Jurassic 
deposits of England, Siberia and Antarctica. 
The new Permian insect, found in conchostracan-bearing beds of 
the Mount Glossopteris Formation, Ohio Range, is a small but well 
preserved nymph. Since very little is known of nymphal forms of 
Paleozoic insects and especially since no venational pattern is discern- 
ible in the wing pads, the ordinal affinities of the fossil cannot be 
determined with any degree of certainty. However, the specimen is 
very close to a Permian nymph, Uralonympha Zalessky, described 
from Tchekarda, in the Ural Mountains of the USSR, and similar 
to another, Permoleuctropsis Martynov, from a Permian deposit 
near Orenburg, USSR. The similarity of the new nymph to Uralo- 
nympha is especially strong in the form of the prothorax and the 
position of the wing pads (see figure 6). The Antarctic species is 
accordingly being assigned to the genus Uralonympha , in preference 
to making another separate genus that could not be satisfactorily 
distinguished from Uralonyjnpha at the present state of our knowl- 
edge. 
The ordinal position of these nymphs is conjectural. Uralo- 
nympha has generally been considered an immature form of a stone- 
fly (Zalessky, 1935; Sharov, 1962) but there is an equally good 
possibility that it belongs to the Protorthoptera. Until a series of 
such nymphs has been found in association with numerous adults, 
the affinities of Uralonympha and other little-known nymphs of the 
Paleozoic will remain obscure. For the present, Uralony?npha is best 
considered a member, incertae sedis , of the order Perlaria.
