After examining the type of Lutzomyia (Lutzomyia) cruzi (Mangabeira, 1938), kept in the collection of the Instituto Oswaldo Cruz (Rio de Janeiro), under number 941, and 74 male specimens of the species, mostly from the type locality (Camapuan, State of Mato Grosso do Sul), the Authors verified that the basal tuft of the coxite is composed of only four foliaceous setae, and not six, as stated by Mangabeira, due the superposition of the two coxites holotype. A redescription of the male based on the holotype and a description of the previously unknown female are presented.
