Common marauding katydid Metaballus frontalis, copyright William Archer.

Belongs within: Tettigonioidea.

The Tettigoniinae, shield-backed katydids, are a group of katydids that often have the pronotum produced rearwards over the front of the abdomen. They include both diurnal and nocturnal species with some feeding by day but calling and mating by night (Rentz 1996).

Characters (from Rentz 1996): Fastigium of vertex as broad as width of first antennal segment to half width of same; fore tibia bearing a single spine on posterior margin of dorsal surface; hind tarsus with plantula, which is usually half length of first tarsal segment.
