The first Elcanidae (Orthoptera, Elcanoidea) from the Daohugou fossil bed of northeastern China

Abstract

A new species of Elcanidae (Orthoptera, Elcanoidea), Parelcana pulchmacula sp. nov., is described based on four new specimens from the Middle Jurassic Jiulongshan Formation of northeastern China. The new species differs from all other known Archelcaninae species by its combination of wing-venation characters. This new finding improves our knowledge of variation on wing venation in elcanid insects and constitutes the first record of Elcanidae from the Daohugou fossil bed (Yanliao Biota) of northeastern China.
