An incomplete grylloblattid forewing has been found recently at a locality near Colenso (Prevec et al.
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.
An incomplete grylloblattid forewing, which has been recently found at a locality near Colenso (Prevec et al.
1] are features typical of two grylloblattid families, viz.
The fauna of grylloblattid insects (Grylloblattida) of the Lower Permian locality of Tshekarda.
Systematics, phylogeny and evolution of grylloblattid insects (Insecta: Grylloblattida).
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.
Grylloblattids of the family Chaulioditidae (= Tomiidae syn.
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].
