| ABSTRACT ItatingamyiaAlbuquerque, 1979 is rare in collections, with only nine specimens preserved in museums. Two species are known, and their placement within Muscidae was never tested using molecular data. Here, we estimate the position of Itatingamyia within Muscidae with mitochondrial (COI) and nuclear (AATS, CAD, and EF1-α) markers using Maximum likelihood and Bayesian posterior probabilities as optimality criteria. According to our results, we propose to classify Itatingamyia as a Cyrtoneurininae. We also describe the previously unknown female and egg of Itatingamyia couriaeHaseyama and de Carvalho, 2011 and expand the known distribution of this species to the state of Minas Gerais, Brazil, through the discovery of 13 new specimens there. We also... |

| Traditionally, the Drosophila guarani species group has been divided into two subgroups: the guarani and the guaramunu subgroups. Two, out of the four species included in this research, are members of the guarani subgroup (D. ornatifrons Duda, 1927 and D. subbadia Paterson & Mainland, 1943) and two are included in the guaramunu subgroup (D. maculifrons Duda, 1927 and D. griseolineata Duda, 1927). However, some authors have suggested that D. maculifrons and D. griseolineata are much closer to some species of the Drosophila tripunctata group than to some of the species of the guarani group. To add new data to the matter under dispute, Polyacrylamide Gel Eletrophoresis (PAGE-SDS) was used for the analysis and comparison of protein composition and... |

| A new genus of spittlebug is described to include Gervasiella oakenshieldi sp. nov. (holotype male from Brazil, state of Paraná, municipality of Piraquara, Mananciais da Serra at 25°29'46"S, 48°58'54"W, 1000 m a.s.l., 15.XI.2008, P.C. Grossi leg., deposited in DZUP). In addition, Aeneolamia bucca Paladini & Cavichioli, 2013 is transferred to Gervasiella gen. nov. based on the results of a cladistic analysis. Gervasiella gen. nov. can be distinguished from the other cercopid genera by the following: postclypeus inflated with upper portion black and basal one yellowish; color of tylus distinct from color of head and rostrum, barely reaching mesocoxae. Gervasiella oakenshieldi sp. nov. is diagnosed by having the head black with tylus white, postclypeus in... |

| Credible biological research depends on accurate species identifications, reliable scientific names, and an evolutionary context provided by a phylogeny or phylogenetic classification. The emphasis on such taxonomic services has detracted from the fundamental taxonomic research necessary to create and sustain such knowledge systems. A taxonomic declaration of independence is presented, emphasizing the unique mission, goals, and needs of taxonomists and taxonomic (collection-based) institutions and the non-experimental yet scientifically rigorous epistemology of taxonomy. At the same time taxonomic interdependence is declared. Questions pursued by taxonomists are planetary in scale and can only be answered given international collaboration and coordination... |

| ABSTRACT Even though nest architecture has been useful for phylogenetic inferences among the Thamnophilidae (Aves: Passeriformes), the nests of only three out of five species of Myrmoderus (Ridgway, 1909) are known to science. Here we describe the nests, eggs, and nestling of the Squamate Antbird Myrmoderus squamosus (Pelzeln, 1868). Two nests were bulky bottom-supported cups, measuring 7.3 and 12 cm in maximum outside diameter, with a noticeably smaller egg cup, and they were placed within the crown of short, broad-leafed plants. Eggs were short-oval, with chalky white background color, and purple blotches and streaks more concentrated in the large end. One nestling was dark reddish grey, with bluish white feet, pinkish gray tarsi, and a blackish bill... |

| All members of Triatominae subfamily (Heteroptera: Reduviidae), potential vectors of Trypanosoma cruzi etiologic agent of the Chagas disease, feed on blood. Through evolution, these bugs have fixed special morphological, physiological, and behavioral aptations (adaptations and exaptations) adequate to feed on blood. Phylogeny suggests that triatomines evolved from predator reduvids which in turn descended from phytophagous hemipterans. Some pleisiomorphic traits developed by the reduvid ancestors of the triatomines facilitated and modeled hematophagy in these insects. Among them, mouthparts, saliva composition, enzymes, and digestive symbionts are the most noticeable. However, the decisive step that allowed the shift from predation to hematophagy was a... |

| ABSTRACT: Although root rot is one of the major diseases affecting Brazilian cassava (Manihot esculenta Crantz.), little is known about the diversity of root rot pathogens. In this study, diseased plants exhibiting root rot symptoms were collected from cassava-producing regions in five Brazilian states: Bahia, Sergipe, Paraíba, Maranhão, Tocantins, and Paraná. Seventy isolates were obtained and assigned to species complexes based on rDNA's ITS (internal transcribed spacer of the ribosomal DNA) region (ITS1, ITS2 and 5.8S). A total of seven species complexes was found belonging to the genus Fusarium (56/74), followed by Lasiodiplodia (8/74), Neoscytalidium (6/74), and Diaporthe/Phomopsis complex (2/74), Phytophthora, and Corallomycetella (1/74 each). These... |

| A study of phylogenetic relationships of the genera of Mesembrinellinae and of the species of Eumesembrinella Townsend, 1931, on the ground of shared derived character states (synapomorphies) is presented. Resulting the following assumption: Laneella Mello, 1967 presenting sister group relationship with all other Mesembrinellinae, followed by Souzalopesiella Guimarães, 1977, M. peregrina Aldrich, 1922 that was isolated from Mesembrinella Giglio-Tos, 1893. Mesembrinella was considered paraphiletic, its species were judged in changeable positions at the bifurcation point of analysis of Albuquerquea Mello, 1967 with the tricotomic interrelationships of Thompsoniella Guimarães, 1977, Huascaromusca Townsend, 1918 and Eumesembrinella Townsend, 1931.

| Polychaetes are metameric worms recognized for having parapodia, chaetae, and nuchal organs. Some authors have extended the Annelida to include Pogonophora, Echiura, and Clitellata. These suggestions are insufficient to generate a monophyletic group. They do not take into account two very large and important clades that in a cladistic analysis at a higher level are shown to be nested within the Annelida: the Ecdysozoa (arthropods and related taxa) and Enterocoela (deuterostomes and related taxa). Evolutionary histories of most characters across metazoan phyla are still very poorly known. Metameres and coeloms have been considered homoplastic in the literature, and yet the homeobox genes responsible for the expression of metamerism and of paired appendages,... |

| The Oweniidae consist of five genera of tubiculous polychaetes occurring in all oceans from tropical topolarareas: Owenia Delle Chiaje, 1842, Myriochele Malmgren, 1867, Galathowenia Kirkegaard, 1959, Myriowenia Hartrnan, 1960 and Myrioglobula Hartrnan, 1967. The group is regarded as monophyletic based on the presence of dense fields of bidentate neuropodial hooks. Fourteen species were submitted to a cladistic analysis in PAUP 3.1.1 with the usage of 19 morphological characters.The taxonomic status of the ingroup taxa could be evaluated and it has been found that: (1) Owenia, Myriowenia and Myrioglobula are monophyletic, and (2) Myriochele, and Galathowenia are both paraphyletic taxa. |

| Psammocyclopina georgei sp. n. is described from submersed sands in the Magellan Strait, South Atlantic Ocean. This is the second species of the genus, previously known only from the Indian Ocean (Mozambique). Psammocyclopina Wells, 1967 is the sistergroup of Metacyclopina Lindberg, 1953. Psammocyclopinidae fam. n. is accordingly proposed to unify these genera into one monophyletic unit. The sistergroup of the new family is a cluster of cyclopinid genera composed of Cyclopinodes Wilson, 1932, Pseudocyclopina Lang, 1946, Parapseudocyclopinodes Lindberg, 1961, Hemicyclopina Herbst, 1952, Procyclopina Herbst, 1955, Heterocydopina Plesa, 1968, Neocyclopina Herbst, 1952, and an as yet undescribed new genus (Martinez Arbizu, in prep.).

| An alternative proposition for the analysis of the diagnostic states of the pronotum in the Centrotinae and Membracinae (sensu Strümpel) is presented. In this analysis, a linear transformation series is proposed for this character, departing from the state found in Tolania Stal, 1858 changing to an intermediate state in Centrotinae, which is still treated as plesiomorphic when compared with the one found in Membracinae. The transformation series thus defined, clarifies the problems related to the monophyly of the Membracidae, which is herein supported by the state of pronotum previously used to define the Centrotinae. This later taxon is treated as paraphyletic. The monophyly of the Membracinae is unquestioned, but its sister group is still unknown.... |

| A new species of Mycale Gray, 1867 bearing raphidotoxas is described from the Namibian coast (SE Atlantic). Mycale (Aegogropila) kolletae sp. n. is characterized by having raphidotoxas up to 590 µm long, three distinct categories of anisochelae, two categories of sigmas, very small raphides, and most of all, by toxas serrated in an unusual pattern (on the inner parts of all three bends). Mycale magnirhaphidifera Van Soest, 1984 is redescribed from the Brazilian coast, based on a population from the northern São Paulo State coastline. The remaining two species with raphidotoxas, viz. Mycale rhaphidotoxa Hentschel, 1912 and M. mannarensis Thomas, 1968 are revised. Levi's (1963) record of Carmia macilenta (Bowerbank, 1866) for the South African coast was... |
