ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others.

ABSTRACT To correct errors in previous catalogs and update the Brazilian fauna, thirty-five species of Darwin wasps erroneously reported for Brazil are removed from the Taxonomic Catalog of the Brazilian Fauna, belonging to the following subfamilies: Anomaloninae (2 species), Banchinae (1), Campopleginae (8), Cremastinae (2), Cryptinae (8), Phygadeuontinae (3), Pimplinae (8), Tersilochinae (2), and Tryphoninae (1). Most species were incorrectly cataloged due to an incorrect interpretation of the species list created by Costa Lima in 1962, which mentions species occurring in neighboring countries but does not confirm their presence in Brazil. Thus, the Brazilian fauna of Ichneumonidae currently corresponds to 234 genera and 1,038 species.

ABSTRACT The names of two genera and eleven species belonging to Hymenoptera are unavailable. They were published by Francisco Dias da Rocha in 1908 for species from the state of Ceará (Brazil) and attributed to William H. Ashmead. The genus names proposed here as nomina nuda are: Mesopteromalus (Pteromalidae) and Rochai (Ichneumonidae). The species names proposed as nomina nuda are Trichoporus abdominalis, Tetrastichus balteativentris (Eulophidae), Eupelmus myrtaceae (Eupelmidae), Eurytoma cearae (Eurytomidae), Mesopteromalus abdominalis (Pteromalidae), Syntomaspis loranthaceae (Torymidae), Urogaster brasiliensis (Braconidae), Rochai achiaemorpha (Ichneumonidae), Leptacis myrtaceae, Polygnotus brasiliensis, and Synopeas rochai (Platygastridae). The probable relationship between Mesopteromalus abdominalis with Jaliscoa nudipennis Bouček, and between Eurytoma cearae and Rileya cearae Crawford are discussed.

Abstract The genus Nonnus Cresson, 1874 (Hymenoptera: Ichneumonidae: Nesomesochorinae) contains 20 species distributed in the New World and so far, no species of this genus has been recorded for Uruguay. Thus, the objective of this work was to investigate the occurrence, abundance and sex ratio of Nonnus niger (Brullé, 1846) in three different phytophysiognomies in eastern Uruguay.
