According to Moulds (2005), subfamily Tettigadinae includes tribes Platypediini Kato, Tettigadini Distant, and Tibicinini . The latter tribe is characterized as follows: forewing veins CuP and 1A not fused; hind wing veins RP and M free at base; distance between supra-antennal plate and eye about equal to length of antennal plate; uncus exceedingly long and non-retractable within pygofer; aedeagus with ventrobasal pocket present, aedeagus with apical part of theca bearing pair of leaf-like lateral lobes and a non-retractable tubular vesica; male opercula with distinctive S-shape, lateral margins deeply concave, distal margins not reaching distal margins of tympanal cavities, basally not extending beyond meracantha. Genus Katoa Ouchi, 1938 belongs to the tribe Tibicinini based on the above characteristics. Therefore in this paper genus Katoa is transfered to Tettigadinae.
