13. Biogeografia e sistemática dos peixes aulopiformes / Biogeography and systematics of aulopiformes fishes
The Aulopiformes are marine fishes ranging from Early Cretaceous to Recent. Fossil taxa are found in sediments from South and North America, Europe, Asia and Africa. The living forms can be found from shallow coastal estuaries, to the abyssal depths, exceeding 3,000 m. Interrelationships among this group are subject of many studies. The aim of these studies

14. From the Phylogeny of the Satyrinae Butterflies to the Systematics of Euptychiina (Lepidoptera: Nymphalidae): History, Progress and Prospects
We review the various proposals of evolutionary and classification schemes for Satyrinae and particularly Euptychiina butterflies, assessing progress and prospects of research for the group. Among the highlights is the proposal to include Morphini, Brassolini and Amathusiini as part of Satyrinae. Although it is clear that this hypothesis requires further inv

15. Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy
The family Characidae is the most diverse among Neotropical fishes. Systematics of this family are mainly based on pre-cladistic papers, and only recently a phylogenetic hypothesis for Characidae was proposed by the author. That phylogeny was based on 360 morphological characters studied for 160 species, including representatives of families related to Chara

16. Sistemática de Paepalanthoideae (Euriocaulaceae): Filogenia, morfologia e taxonomia de Diphyomene (Ruhland) Trovó / Systematics of Paepalanthoideae (Eriocaulaceae): Phylogeny, morphology, and taxonomy of Diphyomene (Ruhland) Trovó
This thesis consists of a phylogenetic study involving Paepalanthoideae, and a morphological, nomenclatural, and taxonomic survey of Paepalanthus sect. Diphyomene. Chapter I is a phylogenetic study of Paepalanthoideae based on morphological and molecular data (nrITS and trnL-trnL). The monophyly of Rondonanthus, as a sister group of the remaining Paepalantho

17. Estudos de sistemática molecular e de biogeografia histórica do bagre de água doce Pseudoplatystoma Bleeker, 1862 (Pimelodidae) na América do Sul
The catfishes of the Pseudoplatystoma genus are carnivore pimelodids, migratory and important for fisheries in all major river basins from South America. Only three species were recognized for the genus (P. corruscans, P. fasciatum and P. tigrinum), but a new revision raised to eight the number of species (P. fasciatum, P. punctifer, P. orinocoense, P. magda

18. Redescription of a Dasypodini (Xenarthra, Cingulata) from the Quaternary of São Paulo, Brazil, and remarks on the genus Propraopus Ameghino, 1881. / Redescrição de um Dasypodini (Xenarthra, Cingulata) do quaternário do Estado de São Paulo e considerações sobre o gênero Propraopus Ameghino, 1881
This work presents the comparative description of the skull, postcranium and osteoderms of the Dasypodini (Xenarthra, Cingulata) MNRJ 552-V, collected in the quaternary deposits of Gruta de Itaporanga, Sorocaba-SP, Brazil. The skull was CT scanned and compared to those of extant taxa of all three Dasypodidae subfamilies, while the postcranium was compared to

19. Taxonomic review and interspecific relationships of Lebiasininae (Ostariophysi: Characiformes: Lebiasinidae) / Revisão taxonômica e relações interespecíficas de Lebiasininae (Ostariophysi: Characiformes: Lebiasinidae)
The subfamily Lebiasininae has been traditionally divided into two genera: Lebiasina and Piabucina. Historically, such division has been contested due to the inconsistency of the diagnostic characters differring both genera. To investigate the relationships among the Lebiasininae and the validity of Lebiasina and Piabucina, 59 representatives of the Lebiasin

20. Relações filogenéticas da superfamília Doradoidea (Ostariophysi, Siluriformes) / Phylogenetic relationships of the superfamily Doradoidea (Ostariophysi, Siluriformes)
The superfamily Doradoidea (Siluriformes) is composed of two Neotropicalendemic families: Doradidae and Auchenipteridae. The sister-group relationship between these families has been corroborated by previous studies of both morphological and molecular data. Previous studies have also provided support for evolutionary relationships between doradoid genera and

21. Phylogenetic study of the Characinae (Teleostei: Characiformes: Characidae) / Estudo filogenético de Characinae (Teleostei: Characiformes: Characidae)
Um dos principais desafios na ictiologia Neotropical moderna refere-se à sistemática de Characidae, uma família com aproximadamente 950 espécies, dois terços da diversidade de Characiformes. Recentemente, tem sido sugerido que subunidades de Characidae sejam primeiramente estudadas e reconhecidas visando um melhor entendimento da sistemática da famíli

22. Sistemática molecular de Trichosporon spp. baseada em genes ribossomais e sua correlação com fatores de virulência e epidemiologia / Molecular systematics of Trichosporon spp. based on ribosomal genes and its correlation with virulence factors and epidemiology
Yeasts of the genus Trichosporon appear as emerging pathogens with high rates of morbidity and mortality in immunocompromised patients and is becoming increasingly widespread. The significant increase of invasive tricosporonose and the controversial identification of this kind imply an epidemiological deficit which in turn complicates the understanding of th

23. Systematics and Biogeography of the Didymopanax group of Schefflera (Araliaceae)
Schefflera is the largest genus in the angiosperm family Araliaceae, with about 900 species, of which c. 300 belong to five subgeneric groups in the Neotropical region. Previous phylogenetic studies of Schefflera have been limited to a small number of species from this region, and very little is know about phylogenetic relationships in the Brazilian-centered

24. Polimorfismo no padrão de manchas tegumentares de larvas e adultos de Ceraeochrysa caligata (Neuroptera: Chrysopidae) e redescrição dos instares larvais
Ceraeochrysa caligata (Banks, 1945) is one of the several species of Ceraeochrysa Adams, 1982 that occur in agroecosystems of the Neotropical region and show potential for use in biological control programs. However, little is known about its biology, partly because of the poor status of the systematics of this group. To help in the identification of C. cali
