Abstract excerpt
BACKGROUND: Accurate species delimitation is fundamental to biodiversity research but remains challenging in taxonomically controversial groups exhibiting morphological plasticity. The Tetrix japonica complex (Orthoptera: Tetrigidae) includes widespread populations and several nominal species defined primarily by variable traits such as wing dimorphism. The validity of these taxa and the genera based upon them...
