Abstract
The genus Gryllus includes 82 described species that occur in America from Canada to Argentina as well as
in several areas of Africa, Europe and Asia. There are 12 species in South America, which were described in
the nineteenth century based on a small number of samples and inconsistent characters such as body
coloration and external morphology. The aim of this article is to redescribe Gryllus argentinus Saussure,
1874 collected in the urban areas of Pelotas, Capão do Leão and Rio Grande, in the state of Rio Grande do
Sul, southern Brazil, highlighting phallic sclerites, calling song and body morphometry. We designate the
lectotype male, provide a combination of diagnostic characteristics and discuss the taxonomic situation of
South American Gryllus species
