Arria qinlingensis sp. n., a remarkable new praying mantis from China (Mantodea: Haaniidae)

A new species of mantis, Arria qinlingensis sp. n., is described based on both male and female specimens collected from Qinling Mt., China. This new species has similar external morphology to A. leigongshanensis (Ge and Chen, 2008); these two species represent a mysterious evolutionary clade in the genus Arria Stål, 1877. The discovery of this moss-mimicking mantis species represents the northernmost distribution of the genus Arria. Illustrations and ecological images of Arria species in China are presented, and the images of the final-instar nymph for both sexes of A. leigongshanensis (Ge and Chen, 2008) and the ootheca of Arria qinlingensis sp. n. are illustrated. The distribution of the two species in China is discussed and mapped.
