Thus, the grylloblattid fauna of the South African Lopingian is represented by two families: the dominant Liomopteridae (63% of all grylloblattids) and the considerably rarer Megakhosaridae (22%).
To summarise, the composition of the South African grylloblattid fauna is typically Lopingian, with dominating Liomopteridae, and rare Megakhosaridae and Chaulioditidae.

Systematics, phylogeny and evolution of grylloblattid insects (Insecta: Grylloblattida).
Grylloblattids have been found at a number of Lopingian (Upper Permian) localities in the north-eastern and eastern parts of the main Karoo Basin and in the Lebombo Basin (van Dijk 1997; Van Dijk & Geertsema 1999; Geertsema et al.
The latter assumption is supported by records of grylloblattids, which are known to be associated with cold and moist environments from their early days until the present (e.g., Shcherbakov 2008) contrary to the statement that they are indicative of warmer and drier conditions (Geertsema et al.
This species is characterized by a shortened wing, which is twice as long as it is broad (wings of the majority of grylloblattids are three times as long as broad), and by the stems of RS, MA, MP and CuA thickened basally and at the wing midlength.
However, the latter view must be balanced because differences / similarities between Palaeozoic fossil insect assemblages could be significant at a supra-generic level, as suggested by Bethoux [in press; see also a comparison of several Permian assemblages of grylloblattid insects by Storozhenko (1998) at the familial level].
