Abstract
The antlion species, Glenurus incalis Banks is the most enigmatic species of this New World genus. It was described almost 100 years ago based on a single female collected in the Peruvian Amazon, which until today remained as the only known specimen. Herein I report four new specimens of Glenurus incalis, which were used to thoroughly redescribe the species and to expand its distribution to Brazil. Notes on the other Brazilian species of Glenurus is also presented, including the first record of G. heteropteryx Gerstaecker to the country.
