A new species, Neodexiopsis hirsuta sp. nov. (Diptera, Muscidae), from Palmas, Paraná, Brazil, is described and illustrated here. The proboscis and male terminalia are described using ultrastructural morphology. This new species resembles a member of the Scathophagidae, although the male terminalia have a typical Coenosiini morphology. The maximum-likelihood (ML) and Bayesian Inference (IB) molecular analyses of the cytochrome c oxidase subunit I (COI) sequences for the new species, along with those for four other species of Neodexiopsis found in the same locality and two sequences from GenBank were carried out. The molecular analyses indicated N. hirsuta sp. nov. as closely related to Neodexiopsis rava Snyder, 1957 and Neodexiopsis paulistensis Albuquerque, 1956. N. hirsuta sp. nov. and N. rava are now included in the available Brazilian species key to the genus. The distribution data of the Neodexiopsis species from Brazil has been improved by including N. rava as a new record to Brazil.
