New taxa and records of Gryllacrididae (Orthoptera, Stenopelmatoidea) from South East Asia and New Guinea with a key to the genera

摘要

New records of Gryllacrididae from South East Asia to New Guinea are reported, new taxa are described and type specimens from European collections redescribed. The wing venation of the tegmina and its variation within the family is discussed. A new key to the 50 genera and subgenera of Gryllacrididae occurring in the area from South East Asia to New Guinea is provided. Six genera and two subgenera are introduced as new: Angustogryllacris gen. nov., Minigryllacris gen. nov., Monseremus gen. nov., Siamgryllacris gen. nov., Paraneanias gen. nov., Plexigryllacris gen. nov., Pseudasarcasubgen. nov. of Asarcogryllacris Karny, 1937, Xiphilarnaca subgen. nov. of Metriogryllacris Karny, 1937. Two genera Gigantogryllacris Karny, 1937 and Pardogryllacris Karny, 1937 are reduced to subgeneric status under Gryllacris Audinet-Serville, 1831 and one monotypic genus Cyanogryllacris Karny, 1937 is synonymised with Capnogryllacris Karny, 1937.
