Paravelia Breddin 1898
Genus Paravelia Breddin, 1898 Diagnosis: Species of this genus can be differentiated from other Neotropical genera of Veliinae mainly by the (1) absence of lateral tubercles on the mesoacetabulum and metasternum, (2) tarsomere II of the middle leg usually 4-5 times longer than tarsomere I, (3) pretarsus of the middle and hind legs with setaeshaped arolia and two falcate claws, and (4) macropterous form usually with two maculae on each fore wing, with one basal and the other apical (Andersen 1982; Rodrigues et al., 2014a).Published as part of Rodrigues, Higor Daniel Duarte & Moreira, Felipe Ferraz Figueiredo, 2016, A new species, new synonymy, and notes on Paravelia Breddin (Hemiptera: Heteroptera: Veliidae), pp. 183-188 in Papéis Avulsos de Zoologia (São Paulo) (São Paulo) 56 (17) on page 184, DOI: 10.11606/0031-1049.2016.56.17, http://zenodo.org/record/465655
Taxonomic revision phylogenetic analysis of the subfamily Limnocorinae (Heteroptera: Nepomorpha: Naucoridae)
A subfamília Limnocorinae (Naucoridae) possui quatro gêneros nominais na literatura, entretanto, apenas Limnocoris Stål, 1860 é considerado válido. O presente estudo revisa taxonomicamente as espécies do gênero, bem como a relação filogenética entre elas. Todas as espécies ocorrem na região Neotropical, registradas do sul do Estado de Nevada, nos Estados Unidos, até a região central da Argentina. Historicamente, Limnocoris é um grupo pouco estudado, com trabalhos que concentram basicamente em descrições de espécies, muitas delas, publicadas em estudos isolados, sem muito detalhe. Além disso, é digno de nota mencionar que até o presente momento nenhum estudo que se objetivou classificar grupos de espécies ou mesmo a relação de gêneros dentro das subfamílias utilizando análise filogenética foi realizado até o momento. Através de revisão taxonômica, buscou-se reconhecer os táxons pertencentes ao gênero, bem como suas variações intraespecíficas. A revisão teve ênfase na localização do material-tipo e espécimes adicionais, sempre que possível. Todas as espécies estudadas foram fotografadas e examinadas com o intuito de padronizar o estudo morfológico externo do gênero. Após o estudo dos espécimes-tipo, foi possível propor 15 sinonímias novas, sinônimos juniores entre colchetes: Limnocoris dubiosus Montandon [L. aymarana Poisson]; L. espinolai Nieser & Lopez-Ruf [L. porphyros Nieser & Lopez- Ruf]; L. insularis Champion [L. alcorni La Rivers]; L. malkini La Rivers [L. pulchellus La Rivers]; L. menkei La Rivers [L. birabeni De Carlo]; L. ochraceus Montandon [L. maculatus De Carlo]; L. pallescens (Stål) [L. bergrothi Montandon]; L. pauper Montandon [L. nigropunctatus Montandon]; L. pauper Montandon [L. nigropunctatus Montandon]; L. pectoralis Montandon [L. rivalis Melin]; L. pygmaeus La Rivers [L. solenoides La Rivers]; L. signoreti Montandon [L. brailovskyi La Rivers, L. laucki La Rivers e L. stangei La Rivers]; L. stali Montandon [L. carcharus La Rivers e L. robustus Roback & Nieser]. Além disso, três espécies são revalidadas: L. montandoni La Rivers, L. sattleri De Carlo e L. stali; L. surinamensis stat. nov. é elavada ao status de espécies, e outras 13 espécies novas são propostas. Lectótipos são designados para L. aymarana, L. bergrothi, L. dubiosus e L. signoreti. Com o objetivo de propor uma hipótese de relação de parentesco entre as espécies de Limnocoris, foi elaborada uma matriz de 82 caracteres morfológicos, tendo como método de estudo a máxima parcimônia. A análise utilizando pesagem implícita resultou em 1 árvore mais parcimoniosa; oito sinapomorfias suportam a monofilia do gênero Limnocoris, que se mostrou dividir-se em dois grandes clados separados principalmente pela pubescência da região ventral do corpo. A distribuição geográfica de grande parte das espécies é incrementada com a inclusão de novos registros e, com intuito de facilitar a identificação, mapas de distribuição e uma chave ilustrada é proposta para as espécies estudadas.The subfamily Limnocorinae (Naucoridae) contains four nominal genera in the literature, however, only Limnocoris Stål, 1860 is considered valid. The present study reviews taxonomically the species of the genus, as well as proposes a phylogenetic hypothesis of relation between them. All species occur in the Neotropical region, from southern Nevada in the United States, to central Argentina. Historically, Limnocoris is a poorly studied group, with works concentrate mainly on descriptions of species, many of them, published in isolated studies, without much detail. In addition, up to the present time no study that has aimed to classify groups of species or even the relationship of genera within the subfamilies using phylogenetic analysis has not been performed so far. Through a taxonomic revision, it was sought to recognize the taxa belonging to the genus, as well as their intraspecific variations. The revision has emphasized in the location of the type-material and additional specimens, whenever possible. All species studied were photographed and examined in order to standardize the external morphological study of the genus. After the study of the type specimens, it was possible to propose 15 new synonymies, junior synonyms between brackets: Limnocoris dubiosus Montandon [L. aymarana Poisson]; L. espinolai Nieser & Lopez-Ruf [L. porphyros Nieser & Lopez-Ruf]; L. insularis Champion [L. alcorni La Rivers]; L. malkini La Rivers [L. pulchellus La Rivers]; L. menkei La Rivers [L. birabeni De Carlo]; L. ochraceus Montandon [L. maculatus De Carlo]; L. pallescens (Stål) [L. bergrothi Montandon]; L. pauper Montandon [L. nigropunctatus Montandon]; L. pauper Montandon [L. nigropunctatus Montandon]; L. pectoralis Montandon [L. rivalis Melin]; L. pygmaeus La Rivers [L. solenoides La Rivers]; L. signoreti Montandon [L. brailovskyi La Rivers, L. laucki La Rivers e L. stangei La Rivers]; L. stali Montandon [L. carcharus La Rivers e L. robustus Roback & Nieser]. In addition, three species are revalidated: L. montandoni La Rivers, L. sattleri De Carlo and L. stali; L. surinamensis stat. nov. is elevated to species status and another 13 new species are proposed. Lectotypes are designated for L. aymarana, L. bergrothi, L. dubiosus e L. signoreti. With the aim of proposing a hypothesis of relationship among the species of Limnocoris, a matrix of 82 morphological characters was elaborated, having as method the maximum parsimony. The analysis under implicit weighing resulted in 1 more parsimonious tree; eight synapomorphies support the monophyly of the genus, which has been shown to divide into two clades separated mainly by the pubescence of the ventral region of the body. The geographic distribution of almost all species is increased with the inclusion of new records and, in order to facilitate identification, distribution maps and an identification key are proposed for the studied species
Estudo taxonômico dos gêneros Oiovelia Drake & Maldonado-Capriles, 1952 e Paravelia Breddin, 1898 (Hemiptera: Heteroptera: Gerromorpha: Veliidae)
The Neotropical genera Oiovelia Drake & Maldonado-Capriles, 1952 and Paravelia Breddin, 1898 (Hemiptera: Heteroptera: Veliidae) were studied taxonomically. The first was revised, the known species were redescribed with characters not mentioned in the original description, and four new species were described and illustrated, all of them to Brazil, totaling eight species in the genus. Oiovelia rivicola Spangler was recorded for the first time in Brazil (Amazonas and Amapá), besides expanding the occurrence area for the other described species. In Paravelia, eight new species were described and illustrated through material from seven Brazilian States (Amapá, Amazonas, Maranhão, Bahia, Mato Grosso, Mato Grosso do Sul and Minas Gerais), totaling 55 valid species in the genus. Color photographs of dorsal aspect were obtained for the following species: P. basalis (Spinola), P. biae Spangler, P. boliviana Breddin, P. bullialata Polhemus & Polhemus, P. capillata Drake & Harris, P. capixaba Moreira, Nessimian & Rúdio, P. conata (Hungerford), P. dilatata Polhemus & Polhemus, P. foveata Polhemus & Polhemus, P. itatiayana Drake, P. lanemeloi Moreira & Barbosa, P. manausana Polhemus & Polhemus, P. nieseri Moreira & Barbosa, P. platensis (Berg), P. recens (Drake & Harris), P. rotundanotata (Hungerford), P. spinifera Polhemus & Polhemus, P. splendoris (Drake & Harris) and P. williamsi (Hungerford). Three of these species are recorded for the first time in Brazil: P. plantesis, P. spinifera and P. williamsi. Moreover, the macropterous form of P. capixaba and P. dilatata are described. Finally, in order to summarize the information for species in both genera, a catalog including geographic records, synonymic list, diagnosis, and comments, are presented separately for each genus.Os gêneros neotropicais Oiovelia Drake & Maldonado Capriles, 1952 e Paravelia Breddin, 1898 (Hemiptera: Heteroptera: Veliidae) foram estudados taxonomicamente. O primeiro gênero foi revisado, as espécies conhecidas foram redescritas acrescentando caracteres não mencionados na descrição original, e quatro espécies novas para o Brasil foram descobertas e ilustradas, totalizando 8 espécies. Oiovelia rivicola Spangler foi registrada pela primeira vez no Brasil (Amazonas e Amapá), além de ampliar a área de ocorrência para as demais espécies descritas. Em Paravelia, oito novas espécies foram descritas e ilustradas através do material proveniente de sete Estados brasileiros (Amapá, Amazonas, Maranhão, Bahia, Mato Grosso, Mato Grosso do Sul e Minas Gerais), totalizando 55 espécies válidas para o gênero. Fotografias coloridas do aspecto dorsal foram obtidas para as seguintes espécies: P. basalis (Spinola), P. biae Spangler, P. boliviana Breddin, P. bullialata Polhemus & Polhemus, P. capillata Drake & Harris, P. capixaba Moreira, Nessimian & Rúdio, P. conata (Hungerford), P. dilatata Polhemus & Polhemus, P. foveata Polhemus & Polhemus, P. itatiayana Drake, P. lanemeloi Moreira & Barbosa, P. manausana Polhemus & Polhemus, P. nieseri Moreira & Barbosa, P. platensis (Berg), P. recens (Drake & Harris), P. rotundanotata (Hungerford), P. spinifera Polhemus & Polhemus, P. splendoris (Drake & Harris) e P. williamsi (Hungerford). Três dessas espécies são registradas pela primeira vez no Brasil: P. platensis, P. spinifera e P. williamsi. É apresentada uma chave de identificação para as espécies de Paravelia registradas no Brasil, além da descrição das formas macrópteras de P. capixaba e P. dilatata. Mapas de distribuição foram elaborados para as espécies de Oiovelia e para as novas espécies de Paravelia. Por fim, com o objetivo de reunir as informações para as espécies em ambos os gêneros estudados, os registros geográficos, lista sinonímica, diagnoses e comentários para todas as espécies foram incluídos separadamente para cada gênero
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
