New records, descriptions, and redescriptions of male horse flies (Diptera: Tabanidae) in Brazil

Abstract

Tabanidae Latreille are hematophagous and act as mechanical and biological vectors of several pathogens, and therefore they have been widely studied in both ecology and public health, as well as in taxonomy works. Males are nectarivorous and rarely captured, so for most species they remain unknown. Thus, we aimed to describe/redescribe the males of five species: Esenbeckia osornoi Fairchild, 1942, Acanthocera marginalis Walker, 1854, Dicladocera mutata Fairchild, 1958, Stypommisa aripuana Fairchild & Wilkerson, 1986, and Tabanus mucronatus Fairchild, 1961. Three males are described for the first time and two others are redescribed, we also provide a complete description of the species, including photographs of habitus, head and genitalia.
