Gergithoides Schumacher 1915
No full textGenus Gergithoides Schumacher, 1915 Gergithoides Schumacher, 1915: 126. Type species: Gergithoides carinatifrons Schumacher, 1915 by monotypy. Daruma Matsumura, 1916: 103 (preoccupied). Type species: Daruma nitobei Matsumura, 1916, by original designation. Synonymized by Ishihara (1965a: 208) under the erroneous spelling “ Darma ”. Darumara Metcalf, 1952: 227. New name for Daruma Matsumura, 1916. Synonymized by Gnezdilov (2009: 85) [erroneous: already synonymized by Ishihara (1965a)]. Darma Ishihara, 1965a: 208. Misspelling of Daruma. We follow the definition of the genus given in the key to the genera of Hemisphaeriini proposed by Sun et al. (2012), with the following distinctive set of characters: (1) posterior wing longer than half length of tegmen; (2) frons with complete median carina; (3) lateral margins of frons not elevated and (4) a row of tubercles along lateral margin of frons. Note Ishihara (1965a) was the first to propose Daruma as a junior synonym of Gergithoides, although he should have used the name Darumara as proposed by Metclaf (1952). It seems that Chan & Yang (1994) were not aware of Ishihara’s (1965a) synonymy, as they considered Gergithoides and Darumara as separate genera. More recently, Gnezdilov (2009) reinstated Ishihara’s (1965a) view but erroneously stated that he proposed a new synonymy instead.

G. rugulosus (Melichar, 1906) G. undulatus Wang & Che, 2003 Remarks The species of Gergithoides should be identified based on the comparison of the male genitalia with reliable illustrations. Considering the numerous pending issues regarding the identity of the species of Gergithoides, it is currently unwise to propose an identification key to the species.Published as part of Jérôme Constant & Hong-Thai Pham, 2017, Gergithoides Schumacher, 1915 in Vietnam, with two new species, and taxonomic notes on the genus (Hemiptera: Fulgoromorpha: Issidae), pp. 1-20 in European Journal of Taxonomy 296 on page 4, DOI: 10.5852/ejt.2017.296, http://zenodo.org/record/89414

Gergithoides undulatus – Rahman et al. 2012: 295 [keyed]. — Chen et al. 2014: 37 [keyed (in Chinese)], 38 [distribution map], fig. 2-10 [habitus, details and male genitalia illustrated], 43 [described, recorded from Hainan (in Chinese)]; 188 [distribution, recorded from Hainan (in English)]. Remarks This species was described by Che et al. (2003) based on the male holotype from Guangxi and 10 female paratypes from Hainan. As no male from Hainan was examined to support the attribution of the series of female paratypes by the authors, the consistency of the type series of G. undulatus remains questionable. The specimen and male genitalia illustrated in Chen et al. (2014) are based on material from Hainan and do not match the illustrations provided in the original description. Particularly, and compared to the latter, the following differences can be observed in the specimen from Hainan: (1) vertex more elongate, (2) anal tube with posterior margin roundly emarginate, not bisinuate, and without ante-apical strong constriction, and (3) gonostyli more elongate. Hence, the presence of the species in Hainan still requires confirmation by the examination of male genitalia.Published as part of Jérôme Constant & Hong-Thai Pham, 2017, Gergithoides Schumacher, 1915 in Vietnam, with two new species, and taxonomic notes on the genus (Hemiptera: Fulgoromorpha: Issidae), pp. 1-20 in European Journal of Taxonomy 296 on pages 17-18, DOI: 10.5852/ejt.2017.296, http://zenodo.org/record/89414

Gergithoides rugulosus – Jacobi 1944: 19 [transferred to Gergithoides; recorded from China (Fujian)]. — Metcalf 1958: 120 [catalogued]. — Che et al. 2003: 103 [keyed, recorded from Fujian, Guangxi, Sichuan and Yunnan (in Chinese)], 107 [recorded from Fujian, Guangxi, Sichuan and Yunnan (in English)]. — Rahman et al. 2012 [keyed]. — Gnezdilov et al. 2014: 93 [note]. — Chen et al. 2014: 37 [keyed (in Chinese)], 38 [distribution map], fig. 2-9 [habitus, details and male genitalia illustrated], 43 [described, recorded from Guizhou (in Chinese)], 188 [distribution, recorded from Guizhou (in English)]. Type material examined MALAYSIA: Syntypes of Gergithus rugulosus (examined on photographs, Fig. 8): 1 ♂ [Malacca, Perak] [rugulosus M det. Melichar] [Typus] [NHRS-GULI 000009432] (NHRS); 1 ♀ [Malacca, Perak] [rugulosus M det. Melichar] [Paratypus] [NHRS-GULI 0 0 0 0 29484] (NHRS); 1 ♀ [Malacca, Perak] [rugulosus M det. Melichar] [Syn-typus] [transcriptio Gergithus rugulosus sp. n. ♀, L. Melichar 1906] [Invent. č 3377 / Ent, Mor. Museum, Brno] (MMBC). Remarks This species was described based on 3 syntype specimens (Fig. 8) from southern Malaysia. The genitalia of the male syntype were not illustrated to date. The species was later mentioned from China: from Fujian by Jacobi (1944), from Guangxi, Sichuan and Yunnan by Che et al. (2003), and from Guizhou by Chen et al. (2014). Male genitalia attributed to the species were illustrated by Chen et al. (2014) based on a male specimen from Guizhou. It seems worth mentioning that the specimens from Guizhou are from the same collecting event as female specimens attributed by Chen et al. (2014) to another species, G. carinatifrons, and illustrated as such (see comments under G. carinatifrons). We consider that the specimens illustrated as G. rugulosus and G. carinatifrons by Chen et al. (2014) are actually conspecific and should represent a new species. Subsequently, the presence of G. rugulosus in China remains highly questionable. This issue needs to be solved by the study of the genitalia of the male syntype of G. rugulosus.Published as part of Jérôme Constant & Hong-Thai Pham, 2017, Gergithoides Schumacher, 1915 in Vietnam, with two new species, and taxonomic notes on the genus (Hemiptera: Fulgoromorpha: Issidae), pp. 1-20 in European Journal of Taxonomy 296 on pages 15-17, DOI: 10.5852/ejt.2017.296, http://zenodo.org/record/89414
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
