A new genus with a new species of Shield-back Katydid, with comments on the phylogeny and diagnosis of the genus Kansua Uvarov and the tribe Drymadusini (Orthoptera: Tettigoniidae: Tettigoniinae) from China.

In this paper, a new species, Sichuana cryptospina sp. nov., is described from Sichuan, China. COI genes were used to analyze the phylogenetic relationships with the species belonging to Drymadusini from China. Phylogenetic reconstruction supports the monophyly of Drymadusini while the relationships among genera are still unclear. The new species should be placed in the new genus named Sichuana gen. nov. Additionally, Kansua Uvarov should be moved into this tribe, with supplementary expression of the tribe diagnosis. Types of the new species in this paper are preserved in the Museum of Biology, East China Normal University (ECNU).
