Subscribe/Renew Journal
The present study aimed to establish the diversity of short-horned grasshoppers in the Sunderban Biosphere Reserve. The survey was conducted from April 2011 to March 2013 at 29 different localities of Sunderbans. Altogether 19 species of Acridoidea and Pyrgomorphoidea under 16 genera belonging to 13 tribes of 9 subfamilies spread over 2 families from Sunderban Biosphere Reserve are reported. The distribution of some species differed markedly from one site to another. Among the two families, Acrididae holds the highest number of species, followed by family Pyrgomorphidae. Among them, Gastrimargus africanus africanus (Saussure, 1888), Heteracris pulchra (Bolivar, 1902), Hieroglyphus banian (Fabricius, 1798) and Tristria pulvinata (Uvarov, 1912) are reported for the first time from Sunderban Biosphere Reserve.
