American katydids of the subtribe Viadanina stat. nov. (Orthoptera: Tettigoniidae: Phaneropterinae)

A.V. Gorochov & O. J. Cadena-Castañeda

Abstract. Two genera of the American Phaneropterinae are discussed: Viadana Walker, 1869; Tomeophera Brunner-Wattenwyl, 1878. The former tribe Viadanini is considered as a subtribe (Viadanina Cadena-Castañeda, 2012, stat. nov.) including Viadana, Tomeophera and two other possible genera only; for the genus Anaulacomera Stål, 1873, a separate subtribe (Anaulacomerina Brunner-Warttenwyl, 1878, stat. nov.) is proposed. The genus Ctenophlebia Stål, 1874, gen. resurr. as well as V. transversa Walker, 1869, sp. resurr. and T. piracicabensis (Piza, 1971), sp. resurr. are restored from synonymy to Viadana, C. myrtifolia (Linnaeus, 1758) and T. modesta Brunner-Wattemwyl, 1891, respectively; two former genera are included in the genus Viadana as its subgenera Paraviadana Piza, 1980, stat. nov. and Proviadana Hebard, 1933, stat. nov.; and V. griffini (Giglio-Tos, 1897), comb. nov. is transferred to the latter genus from the genus Tomeophera. The following new taxa (43) from Brazil, Peru, Colombia, Ecuador, Bolivia, Paraguay, French Guiana and Guatemala are described: Arcuadana subgen. nov. (in the genus Viadana); V. (V.) hamata sp. nov.; V. (V.) semihamata sp. nov.; V. (V.) ultrahamata sp. nov.; V. (V.) obliqua sp. nov.; V. (V.) satipo sp. nov.; V. (V.) bulbosa sp. nov.; V. (V.) biloba sp. nov.; V. (V.) aguarico sp. nov.; V. (V.) amboro sp. nov.; V. (V.) piracicabae strelnikovi subsp. nov.; V. (V.) brasiliensis mercadoi subsp. nov.; V. (V.) diegomendesi sp. nov.; V. (A.) cusco sp. nov.; V. (A.) dentata sp. nov.;V. (A.) abbreviata sp. nov.; V. (A.) nulla sp. nov.; V. (A.) appendiculata sp. nov.; V. (A.) ordinaria sp. nov.;V. (A.) o. signata subsp. nov.; V. (A.) decora sp. nov.; V. (A.) arcuata sp. nov.; V. (A.) tristis sp. nov.; V. (A.) barrancoi sp. nov.; V. (A.) brunneri sp. nov.; V. (A.) hebardi sp. nov.; V. (Paraviadana) intermedia sp. nov.; V. (P.) i. atalaya subsp. nov.; V. (P.) cercata sp. nov.; V. (P.) c. cuyabeno subsp. nov.; V. (P.) napo sp. nov.; V. (P.?) aenigma sp. nov.; V. (Proviadana) ornata sp. nov.; V. (Pr.) lobulata sp. nov.; V. (Pr.) proxima sp. nov.; V. (Pr.) illobulata sp. nov.; V. (Pr.) taediosa sp. nov.; V. (Pr.) guatemalensis sp. nov.; T. semilata sp. nov.; T. s. boliviana subsp. nov.; T. ucayali sp. nov.; T. australis sp. nov.; T. modesta angusta subsp. nov. Lectotype for V. (A.) difformis (Brunner-Wattenwyl, 1878) is designated; male of V. (A.) fruhstorferi (Brunner-Wattenwyl, 1891) is described for the first time.
