Abstract

The Palaeozoic archaeorthopteran order Cnemidolestodea Handlirsch, 1937 (sensu Béthoux, 2005; not sensu Aristov, 2014) currently comprises only the family Cnemidolestidae Handlirsch, 1906. They are easily characterized by the presence of a more or less triangular area delimited by the vein MA and the first anterior fork of MP+CuA+CuPa, this last vein having several parallel posterior branches. Dvořák et al. (2021) listed the included genera, and described the new genus and species Piesbergopterum punctatum from the Moscovian of Piesberg (Germany), characterized by the presence of a pattern of rounded spots in numerous cells all over the forewings. Nel & Poschmann (in press) noticed that the Cnemidolestidae show an important diversity of patterns of coloration on their forewings, possibly related to cryptic behaviors in the vegetation.
