| The genus Homodiaetus Eigenmann & Ward, 1907 is revised and four species are recognized. Its distribution is restricted to southeastern South America, from Uruguay to Paraguay river at west to the coastal drainages of Rio de Janeiro State, Brazil. Homodiaetus is currently distinguished from other genus of Stegophilinae by the combination of the following characters: origin of ventral-fin at midlength between the snout tip and the caudal-fin origin; opercle with three or more odontodes; and gill membranes confluent with the istmus. Homodiaetus anisitsi Eigenmann & Ward, 1907, is diagnosed by the caudal-fin with black middle rays, margin of upper and lower procurrent caudal-fin rays with dark stripes extending to the caudal-fin, and 3-6... |

| ABSTRACT Here we provide a checklist of the flies of the families Acroceridae, Mydidae and Therevidae on the state of Mato Grosso do Sul, Brazil. Acroceridae are represented in Brazil by 30 species, and only Philopota tuberculata Westwood is recorded for the state of Mato Grosso do Sul. The three reported species of Mydidae in the state, Gauromydas autuorii (D’Andretta), Messiasia zikani D’Andretta, and Messiasia notospila (Wiedemann) are among the 27 species now known in Brazil. There are 30 species of Therevidae in Brazil, and only one, Cyclotelus kroeberi (Cole) is known to occur in the state. |

| ABSTRACT Synopia ultramarina Dana, 1853 is considered a circumtropical species and was originally described based on material collected from two localities near halfway between the southwestern Africa and northeastern Brazil. The species is redescribed here with samples from Fernando de Noronha Archipelago, Pernambuco state, northeastern Brazil. The material examined was collected by SCUBA diving, from rhodolith beds, in Ressureta Channel, between Meio and Rata Islands. Additional material was collected from off Ceará state coast, during environmental consultancies, by Petrobras S. A., and off Pernambuco state coast, during the Project REVIZEE NE IV. Discussion on morphological variations of the species is presented, based on the studied material and... |

| Phlebotomus oliverioi Barretto & Coutinho, 1941 was originally described based only on the male holotype and has since been considered junior-synonym of Psathyromyia brasiliensis (Costa Lima, 1932). The study of the holotype of Ph. oliverioi allowed us to conclude that the head of this specimen belongs to the genus Psychodopygus and the wings, thorax and abdomen belong to a different species of Psathyromyia. Thus, Ph. oliverioi is a not valid species, and must be removed from the synonym and excluded from the provisions of the International Code of Zoological Nomenclature (Articles 17.2 and 23.8). The specimen was measured, drawn, photographed and the morphological characters are discussed. Lectotype and paralectotypes to Pa. brasiliensis are... |

| A taxonomic review of the genus Neopachylus Roewer, 1913 together with keys to the species for both males and females are presented. Gephyropachylus marginatus Mello-Leitão, 1931 is considered a junior subjective synonym of Neopachylus serrinha Soares & Soares, 1947, and Huralvius incertus Mello-Leitão, 1935 is considered a synonym of Neopachylus nebulosus (Mello-Leitão, 1936). This genus is restricted to southern Brazil, occurring in states of Paraná, Santa Catarina and Rio Grande do Sul. |

| Four new species of Acrosternum from Brazil are described: Acrosternum (Chinavia)immaculatum(Pará, Mato Grosso, Minas Gerais), A.(C.) panizzii (Paraná), A. (C.) pontagrossensis(Paraná)and A. (C.) rideri (Amazonas, Mato Grosso, Goiás, Distrito Federal, Minas Gerais). The external and internal genitalia of both sexes, except of A. (C.) pontagrossensis are studied. A key for the identification of all known species of the genus is included. |

| ABSTRACT. Coptochilus Amyot & Serville, 1843 is distinguishable from the other Neotropical Scutelleridae by the dorsally concave head, with lateral margins of mandibular plates elevated. Here we describe and revise the species of Coptochilus based on general and genital morphological traits. Coptochilus castaneus (Dallas, 1851), once synonymous with C. ferrugineus Amyot & Serville, 1843, is revalidated, and a new species, C. morrisi, is described from French Guiana. A key to the five species in the genus is provided. |

| ABSTRACT In Argentina, Saccocoelioides bacilliformis Szidat, 1973 was described from specimens collected probably in Astyanax bimaculatus (Linnaeus, 1758), but latter it was synonymyzed with Saccocoelioides octavus Szidat, 1970. During the examination of digenetic trematodes collected in different species of Astyanax Baird & Girard, 1854 from southern Brazil, we found specimens identified as Saccocoelioides. A detailed comparison of the morphology of the two species revealed that they should be considered valid, thus this study proposes the revalidation of S. bacilliformis. The traits that allowed the revalidation were: body shape, position of the caecal bifurcation, and the extension of the uterus and vitellarium. Parameters of infections are provided... |
