ABSTRACT The tribe Scatellini comprises 247 species (plus five nomina dubia) that are distributed in all biogeographical regions except Antarctica. The tribe currently includes nine genera. One genus, Scatella Robineau-Desvoidy, 1830, includes six subgenera. To test the monophyly of Scatellini and to understand the phylogenetic relationships among the included genera, a cladistic analysis was performed. The optimization criterion chosen was parsimony using implicit character weighting, and the analysis was based on the morphological characters of adult males and females. The species of eight of nine genera of Scatellini from different geographic regions were studied. Species of the other tribes of Ephydrinae were also included to provide insight on the phylogenetic position of Scatellini within this subfamily. The implied weighting analysis showed that the tribe Scatellini, as currently characterized, is a monophyletic group, as are all the genera included in it. From this analysis, two major lineages emerged: 1. Scatella and its included subgenera; 2. All other genera of Scatellini. The latter clade includes (Thinoscatella (Lamproscatella + Haloscatella)) and the clade (Amalopteryx (Philotelma (Limnellia + Scatophila))). Five subgenera of Scatella were recovered as monophyletic groups: Parascatella Cresson, Synhoplos Lamb, Apulvillus Malloch, Scatella, and Teichomyza Macquart. Neoscatella Malloch is synonymized with Scatella sensu stricto. In the implied weighting analysis, Ephydrini and Scatellini are sister-groups. Based on this phylogenetic reconstruction, the taxonomy of Scatellini is presented at the generic level. A key to the included genera and subgenera is also presented. 24 plus dubia Antarctica genus RobineauDesvoidy, RobineauDesvoidy Robineau Desvoidy, Desvoidy Robineau-Desvoidy 1830 performed females studied subfamily characterized group it emerged 1 2 Thinoscatella Lamproscatella Haloscatella Haloscatella) Amalopteryx Philotelma Limnellia Scatophila.

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. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT Species of two genera of the tribe Discocerinini from the Neotropics are reviewed with an emphasis on the fauna from Brazil. The two species, Orasiopa (Reymontopa ) mera (Cresson, 1939) and Pectinifer aeneus (Cresson, 1918), are described, illustrated and new occurrence data are provided. Phylogenetic relationships of these two genera into the tribe are discussed. To facilitate identification of these species, we have included diagnoses of the Discocerinini and both genera and have also provided an annotated key to the New World genera in this tribe. We have also provided illustrations, photographs, and scanning electron micrographs of external structures and of structures of the male terminalia for included species.

Scatellini was proposed by Wirth & Stone, 1956 and currently includes 242 described species in nine genera. The tribe has representatives in all biogeographic regions and about 70 species occur in the Neotropical Region. Prior to this study, only two species were recorded from Brazil: Scatella obscura and Limnellia itatiaia. In this paper, species of Scatellini from Brazil are reviewed with an emphasis on the fauna from southern Brazil, where six new species have been discovered and are described herein: Scatella praia, S. plaumanni, S. rara, Scatophila darrowae, S. dianneae, and S. prainha. To facilitate identification of the tribe and included genera and species, we have included diagnoses of these taxa and have also provided an annotated key to the Neotropical genera in Scatellini. We have also provided illustrations of structures of the male terminalia of all included species of the genus Scatophila.
