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.
