Taxonomia de espécies de Anurogryllus Saussure, 1877 (Orthoptera, Gryllidae, Gryllinae) do Rio Grande do Sul e do Amazonas: morfologia e bioacústica.

Abstract

Anurogryllus has nowadays 26 valid species that occurs across the entire American continent. Characterized by rudimentary ovipositor, those crickets have subterranean habits, subsocial behavior and parental care. The aim of this work was to extend the taxonomic knowledge of the species of Anurogryllus that occurs in the southern municipalities of Rio Grande do Sul, Brazil, as well as those in the Reserva Florestal Adolpho Ducke, in Manaus, Amazonas. We found three different species in the south of Rio Grande do Sul, Anurogryllus tapes sp. nov collected in municipalities of Canguçu and Capão do Leão, Anurogryllus patos sp. nov from Capão do Leão and Anurogryllus toledopizai (De Mello, 1988) registered in Canguçu, Capão do Leão e São Lourenço do Sul. We also found two species in the Reserva Florestal Adolpho Ducke, Anurogryllus paxillus sp. nov. and Anurogryllus velox sp. nov.. Here we present the descriptions of morphology, the phallic sclerites, the calling sound, as well as the figures of the examined material.
