Gigagryllus omayrae n. gen et n. sp., a new genus of giant field cricket, from the middle Magdalena of Colombia, more precisely from the department of Tolima, in the region of the Armero tragedy, for which this species is dedicated to the memory of Omayra Sanchez, a symbol of the most terrible natural tragedy that has occurred in the recent history of Colombia. Gigagryllus n. gen. is one of the largest genera in America, with a size similar to Titanogryllus, Megalogryllus and some species of Gryllita. The classification of the American Gryllinae is discussed, and a key to the American genera is provided. Besides, genera groups are proposed for the subtribe Brachytrupine (Gryllini) taxa, which differs from Old World genera. Geogryllus n. syn. and Rubrogryllus n. syn. are synonymized under Gryllita and Cophogryllus americanus is considered as nomen dubium, ruling out the presence of subtribe Cophogryllina in America.
奥马伊拉巨蟋属（Gigagryllus）及新物种奥马伊拉巨蟋（Gigagryllus omayrae），一种来自哥伦比亚马格达莱纳中部地区、更确切地说是托利马省（该地区曾发生阿尔梅罗悲剧）的巨型田蟋新属，此物种是为纪念奥马伊拉·桑切斯而命名，她是哥伦比亚近代史上最可怕的自然悲剧的象征。奥马伊拉巨蟋属是美洲最大的属之一，体型与泰坦巨蟋属（Titanogryllus）、巨蟋属（Megalogryllus）以及某些格里利塔蟋属（Gryllita）物种相似。本文讨论了美洲蟋螽亚科的分类，并提供了美洲各属的检索表。此外，还为短距蟋族（Gryllini）的近距蟋亚族（Brachytrupine）类群提出了属组划分，该类群与旧世界的属不同。地理巨蟋属（Geogryllus）新异名及红巨蟋属（Rubrogryllus）新异名被归并到格里利塔蟋属之下，美洲美洲巨蟋（Cophogryllus americanus）被视为存疑名称，排除了美洲存在近距蟋亚族的可能性。
