We describe a new species of horse fly, Esenbeckia (Esenbeckia) auribrunnea it sp. from Rondonia (Brazil) and Vaupes (Colombia), including diagnoses, distributional records, measurements of body and head, photographs in dorsal, lateral and ventral views, and illustrations of genitalia of a female paratype. In addition, we presented an updated and modified key to species in the subgenus described in the last 23 years based on Wilkerson & Fairchild's (1983) key: E. hirsutipalpus Wilkerson & Fairchild, from Mexico, and E. gracilipalpis Chaney & Hall, from Bolivia: E. griseipleura Chainey & Hall, from Bolivia; E peruviana Burger, from Peru; and E rafaeli Limeira-de-Oliveira, from Maranhao state, Brazil. The species E. diaphana (Schiner) from Colombia. and E. distinguenda Lutz & Castro from Rio de Janeiro, Brazil, are not included with justifications.
