Antebasal impression absent; pronotal disc slightly raised.Scutellum triangular, pubescent. Prosternal surface rough; prosternal intercoxal process as wide as prosternum, extended and widened posteriorly beyond procoxa, ending in a triangular shape. Procoxal cavity open posteriorly.

Metatarsal claws appendiculate.</p> <p> <b>Abdomen:</b> Shiny, pubescent, with five visible ventrites. Female genitalia similar to <i>L. triplehorni.</i></p> <p> <b>Etymology:</b> The specific epithet is in honor of Dr. Cleide Costa,on the occasion of her 80 th birthday, for dedicating her career to the study of Coleoptera.</p> <p> <b>Geographical distribution:</b> Southwest Paraná, Brazil.</p> <p> <b>Remarks:</b> Species of <i>Laselva</i> and <i>Andersonaltica</i> Linzmeier & Konstantinov, 2012 share the shiny elytral surface, punctures forming nine striae, and absence of pronotal antebasal transverse impression. They are differentiated by having (<i>Andersonaltica</i> in parenthesis) antennal calli indistinguishable (antennal calli small, generally nearly indistinguishable), antenna filiform (antenna forming a tight club), humeral calli well developed (humeral calli absent or poorly developed), posterior wings present (apterous) and procoxal cavities open posteriorly (procoxal cavities closed posteriorly).</p> <p> Among the Monoplatina genera, <i>Laselva</i> species are very similar to those of <i>Deciplatus</i> Linzmeier & Konstantinov, 2009.They share similar body size, proportions of pronotum, pubescence on elytra, procoxal cavity opened posteriorly and metatarsus inserted subapically. These genera can be easily differentiated by the number of antennomers, 11 in <i>Laselva</i> and 10 in <i>Deciplatus.</i> Surprisingly, some of the main features that separate <i>L. cleidae</i> sp. nov., from <i>L. triplehorni,</i> such as the shape of the anterofrontal and frontal carina and the antenal callus indistinguishable, besides the female genitalia, are very similar among <i>L. cleidae</i> sp. nov., and <i>Deciplatus</i> species. The female genitalia of <i>L. triplehorni</i> and <i>L. cleidae</i> sp. nov., are identical, not being an important character to differentiate them. In a recent study, Furth (2019) pointed out that he could not use the male and female genitalia to separate two <i>Cerichrestus</i> Clark, 1860 species because he did not find enough morphological differences. This genus also belongs to Monoplatina and, as mentionated in Furth’s paper, other researcher had the same experience studying this group. Apparently, in Monoplatina male and female genitalia do not provide informative taxonomic characters.</p> <p> Since Chapuis (1875), procoxal cavities, whether opened or closed, have been suggested as a character to separate Oedyonichina (opened posteriorly) from Monoplatina (closed posteriorily). Besides, other caracteristics used to define Monoplatina are punctured-striate elytra and the globosely swollen visible on tarsomere IV of metatarsus (Scherer, 1983; Linzmeier & Konstantinov, 2012), this last characteristic also shared with Oedyonichina species. However, <i>Laselva</i> and <i>Deciplatus</i> have the procoxal cavities opened posteriorly and were included in Monoplatina by Furth (2007) and Linzmeier & Konstantinov (2009). Currently, it is unclear if this character changed in some Monoplatina genera or if these two genera do not belong to this taxon. As Monoplatina is very diverse, poorly studied and no phylogenetic studies exist, this issue, as well as evolutionary history of Monoplatina, may be resolved based on a comprehensive phylogentic study.</p>Published as part of <i>Rech, Tarcila & Linzmeier, Adelita Maria, 2020, First species of Laselva Furth from Brazil (Chrysomelidae: Galerucinae: Alticini), pp. 1-4 in Papéis Avulsos de Zoologia 60 (9)</i> on pages 1-4, DOI: 10.11606/1807-0205/2020.60.special-issue.09, <a href="http://zenodo.org/record/4614235">http://zenodo.org/record/4614235</a>
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
