Abstract

Abstract Triozocera Pierce, 1909 is the largest genus of Corioxenidae, comprising 33 species recorded from all continents except Antarctica. The Americas harbor ten species. South America currently has only two species, both from Brazil. Herein, we describe the third Brazilian species, Triozocera titania sp. n., and provide an identification key to the American species of Triozocera . This new species was collected in the Serra dos Órgãos National Park in the Serra do Mar Mountain range, at an altitude above 1700 m.
