Reconstruction of Paleuthygramma tenuicornis, from Grimaldi & Engel (2005).

Belongs within: Archaeorthoptera.

The Caloneurodea are an extinct group of cursorial insects known from the Late Carboniferous and Permian (Grimaldi & Engel 2005). They are little known with most species represented by few specimens.

Characters (from Grimaldi & Engel 2005): Antennae long, multisegmented; fore and hind wings with similar shape, venation and texture; wing veins strongly convex and concave, CuA and CuP unbranched and nearly parallel (occasionally fused) in both wing pairs; hind wing with anal area absent; tarsi five-segmented; cerci (where known) unsegmented.
