Genus Macroscirtus Pictet, 1888 Synonym Macroscyrtus Bolívar, 1893. The name Euthypoda Karsch 1886 with the type species E. difformis, designated by monotypy in Karsch 1892, is a junior synonym of Vetralla [quadrata] Walker 1869 (Kirby 1891). The type species designation of E. acutipennis by Kirby (1906) is invalid. Diagnosis. Macroscirtus can be separated from the other genera of Mecopodinae by the following combination of characters: fastigium of vertex about 2 times broader than antennal scapus; prosternum armed; tegmina longer than pronotum but not reach mid of hind femora; hind wings reduced or nearly missing. Male tegminal stridulatory organs missing except possibly in M. acutipennis, which has at least asymmetrical tegmina. Tentative key to the species of the genus Macroscirtus 1 Male tegmina completely symmetrical, rounded at apex, without stridulatory organ................................. 2 - Male tegmina asymmetrical, pointed at apex, with stridulatory organ........................ Macroscirtus acutipennis 2 Pronotal disc bright yellowish........................................................................... 3 - Pronotal disc dark brown............................................................................... 4 3 Tegmina longer than half of abdomen..................................................... Macroscirtus bicolor - Tegmina not longer than half of abdomen......................................... Macroscirtus brunneotestaceus 4 Hind wings more than two third as long as tegmina...................................... Macroscirtus brevipennis - Hind wings about half as long as tegmina.................................................................. 5 5 Hind femora completely brown; subgenital indentation edge little or more concave............... Macroscirtus kanguroo - Hind femora with mottled brown external face, internal and ventral faces completely pale yellow; subgenital indentation edge straight................................................................... Macroscirtus kekeunoui sp. nov.
