Neduba
shield-back katydid
Neduba is a genus of shield-back katydids (Tettigoniidae) endemic to North America. The genus comprises 21 described species, including one extinct species (N. extincta). A 2021 revision established species boundaries using molecular phylogenetics, morphology, quantitative analysis of calling songs, and karyotypes. The group represents a relict lineage whose diversification reflects cycles of allopatric isolation and secondary contact in western North America.
