Taxonomy
Family:
Tetrigidae
Subfamily:
Batrachideinae
Tribe:
Species Status:
Tettigidea
is one of two genera in the subfamily Batrachideinae, characterized by the possession of antennae with over 19 segments; middle femurs possessing a broad shallow channel on the dorsal surface; and the front margin of the pronotum usually rounded or extending over the head (Hancock, 1906; Blatchley, 1920). In the Tetriginae, the antennae have fewer than 15 segments; the middle femurs are laterally compressed and carinate dorsally; and the front edge of the pronotum is usually truncate except in Nomotettix, where it is angulate and projecting forward.
