Análise filogenética do gênero Formicivora Swainson, 1825 (Aves: Passeriformes: Thamnophilidae) baseada em caracteres morfológicos e vocais
… history characters was conducted to test the monophyly of Fomlicivora, to define its limits and to develop a phy]ogenetic hypothesis for the genus. Primary homologies were hypothesized and coded as 56 characters for 26 terminal taxons that included 251hamnophilid and one formicariid species. …

Phylogeny of the wasp subfamily Metopiinae and patterns of speciation in the Exochus albiceps species-group
… Thus, there have been some doubts regarding the monophyly of the subfamily as currently circumscribed, whether the subfamily renders others paraphyletic, what genera should be contained within Metopiinae, and how these genera are interrelated. The results presented here represent only a first …

Relações filogenéticas do complexo de espécies "Cichlasoma" facetum com clados da tribo Heroini (Perciformes: Cichlidae)
… octofasciatum (Caquetaia + Petenia))))))). The monophyly of the tribe Heroini as proposed by KULLANDER (op. cit.) is corroborated by the apomorphic states of the characters related to the anal fin. The monophyly of the "C." facetum species complex is supported by two unpublished apomorphic …

Relações filogenéticas na família Balanidae (Leach, 1917) sensu Newman & Ross, 1976 (Crustacea, Cirripedia)
… it attained its current status. However, its monophyly and relationship have not been phylogenetically examined and the relationships of Balanidae to other groups of Balanoidea have not been established yet. This study was directed to analyze the monophyly of the family and the groups within …

A molecular approach to questions in the phylogeny of planktonic sarcodines
… and should be discarded. The respective monophyly of the Acantharea and the Polycystinea were supported in all analyses accomplished. The origin of the sequences was confirmed by in situ hybridization experiments. SSU rRNA gene sequences for the solitary spumellarian Thalassicolla …

Phylogenetic relationships of the African species of the genus Merxmuellera Conert (Poaceae: Danthonioideae)
… data sets to further test the hypothesis of non-monophyly of Merxmuellera sensu lato. The results reveal that despite high levels of resolution, the morphological data yield poorly supported phylogenies due to high levels of homoplasy in the dataset.

A synopsis of the genus Octopoma N.E.Br. (Ruschioideae) using morphology, 5S NTS and psbA - trnH spacer regions
… study was, therefore, undertaken to test the monophyly of the genus, and to draw up new taxonomic circumscriptions.

Molecular Phylogenetics of Perciform Fishes Using the Nuclear Recombination Activating Gene 1
… molecular datasets, to date, testing the monophyly of the Perciformes and relationships of its suborders, including the Percoidei. Analyses are performed using a 1425-1431 base fragment of exon three of the single copy, nuclear recombination activating gene 1 (RAG1). Results of these tests …

Revisão da hipótese de monofiletismo da família Aplocheilidae, Bleeker (Cyprinodontiformes - Aplocheiloidei)
The hypothesis of monophyly and inter relationships of the family Aplocheilidae are reexamined. The analysis is based on morphology, primarily osteology, of 25 species. It includes 130 characters, of which 34 are new; 30 are personal communications by Costa and the remaining are from Parenti's …

Análise filogenética dos Mesoeucrocodylia basais da América do Sul e a evolução do Gondwana (Archosauria: Crocodyliformes)
… under bootstrap analysis and Bremer indexes. The monophyly of the families Peirosauridae, Baurusuchidae, and Uruguaysuchidae were confirmed, although a few taxa were transferred to maintain monophyly. Three previously unrecognized groups were identified to maintain a monophyletic taxonomy. Brooks …

Systematics, evolution and biogeography of the Southern African burrowing scorpions, Opistophthalmus C.L. Koch (Scorpiones, Scorpionidae)
… sequence) data. Futher aims were to test the monophyly of Opistophthalmus and of the family Scorpionidae, and to determine their phylogenetic positions with respect to other scorpionoid families and genera.

New delimitations and phylogenetic relationships of Sabiceeae (Ixoroideae, Rubiaceae) and revision of the Neotropical species of Sabicea Aubl.
… previously with strong conflicts. The monophyly of Sabiceeae including its all established genera or the monophyly of any non-monotypic genus traditionally included in this tribe has never been examined using molecular data sets. Sabicea, the type and most species rich genus of the …

A molecular phylogeny of the families and orders of Collembola (Arthropoda: Hexapoda) using the 18S rDNA gene
… of the group. Some authors have questioned the monophyly of the order Poduromorpha, as well as the supraordinal categories Arthropleona and Symphypleona (s.l.). In addition the specific phylogenetic affinities of Poduridae, Actaletidae, and Tomoceridae are unresolved.

Descrição de quatro novas espécies de Belostoma Latreille, 1807 e análise cladística do grupo B. plebejum sensu Nieser, 1975 (Insecta: Heteroptera: Belostomatidae)
… were to conduct a cladistic analysis to test the monophyly of B. plebejum species group and to develop a phylogenetic hypothesis for the group. During the study of the specimens, four new species of the group were discovered and described, being employed as components of the ingroup in the …

Phylogenetic relationships of the Genus Andreaea Hedw.(Andreaeceae,Bryophyta) as inferred from RPS4 and TRNL-F sequences and morphology
… hypothesis. The inferred phylogeny supported the monophyly of the genus. However, the monophyly of most infra-generic groups was largely contradicted. The putative subgenus Chasmocalyx is monotypic with A. nivalis as the sole species, whereas A. australis and A. nitida were resolved within the …

Systematics of the Notonemouridae (Plecoptera) of southern Africa
… barcode in the Notonemouridae, a test of the monophyly of the genera, the construction of a phylogeny for the southern African Notonemouridae and the identification of clade synapomorphies.

Evolutionary relationships in Afro-Malagasy Schefflera (Araliaceae) based on nuclear and plastid markers
… Afro-Malagasy Schefflera, this study tested the monophyly of Afro-Malagasy Schefflera and of each of its two proposed subclades. Trees based on this molecular data were used to examine patterns of morphological evolution and biogeography among species in the clade. Results support the monophyly …

Taxonomy and phylogeny of red-tailed francolins (Genus Peliperdix)
… were used to identify diagnosable taxa, test the monophyly and reconstruct the phylogeny of the Red-tailed Group. Sixteen exemplars of the Red-tailed Group (representing all species and nearly all subspecies currently recognised in the genus Peliperdix) from different geographical localities were …

Mollecular Phylogeny of tribolium (Danthoniodeae: Poaceae) and its taxonomic implications
… analysis retrieved Karroochloa as polyphyletic. Monophyly of Schismus is strongly supported. The Australasian species form a monophyletic clade. Data support early divergence of the Merxmuellera species and Pseudopentameris macrantha.
