The effect of the chronic consumption of water contaminated with residual concentrations of DDT’s metabolites (DDD—dichlorodiphenyldichloroethane and DDE—dichlorodiphenyldichloroethylene) found in the environment were evaluated on the biometric, hematological and antioxidant system parameters of the hepatic, muscular, renal and nervous tissues of Wistar rats. The results showed that the studied concentrations (0.002 mg.L−1 of DDD plus 0.005 mg.L−1 of DDE) could not cause significant changes in the hematological parameters. However, the tissues showed significant alteration in the activity of the antioxidant system represented by the increase in the activity of the enzymes gluthathione S-transferases in the liver, superoxide dismutase in the kidney, gluthathione peroxidase in the brain, and several changes in enzymatic activity in muscle (SOD, GPx and LPO). The enzymes alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST) were also evaluated for the amino acids’ metabolism in the liver, with ALT showing a significant increase in the exposed animals. In the integrative analysis of biomarkers (Permanova and PCOA), the studied concentrations showed possible metabolic changes and damage to cellular structures evidenced by increased oxidative stress and body weight gain among the treated animals. This study highlights the need for further studies on the impact of banned pesticides still present in soils that may induce adverse effects in organisms that may prevail in future generations and the environment.

A species is newly recorded from Paraguay, Sylvicanthon monnei Cupello and Vaz-de-Mello, 2018, and the previously dubious record of Sylvicanthon candezei (Harold, 1869) from the country is confirmed. Agamopus viridis Boucomont, 1928, Pseudocanthon chaquensis Nazaré-Silva and Silva, 2021, and Pseudocanthon pantanensis Nazaré-Silva and Silva, 2021 are newly recorded from Paraguay, and Pseudocanthon xanthurus (Blanchard, 1846), already known from humid southern areas of the country, is newly recorded from its northern Dry Chaco. The publication date of P. xanthurus—1846, not 1843, 1845, or 1847 as previously mentioned—is clarified, and additional data on the chromatic population structure of Bolbites onitoides Harold, 1868 in Paraguay are presented.

The genus Phaonantho Albuquerque (Anthomyiidae) comprises three species: P. mallochi (Curran), P. benevola Couri, and P. sordilloae Pamplona & Couri. These species are distributed in the neotropics. In this study, we updated the distributional knowledge for Phaonantho species, including the first record of the genus in Bolivia, Paraguay, Peru, and Mexico, and additional new records to Brazil.

Psychoda Latreille is one of the largest genera of Psychodidae, with around 450 species, from which more than 130 are known from only one of the sexes. This is a result of the high diversity, sympatry of close related species and scarcity of diagnostic characters to accurately associate males and females in this genus. Here we describe a new species, Psychoda dactyla sp. n., from Brazil, Amazonas, São Gabriel da Cachoeira with morphological description of male and female specimens associated by DNA-barcoding.
