Ramiplectrus catiensis, a new genus and a new species with branched male antennae and long metatibial spurs from Vietnam (Hymenoptera: Eulophidae)
Get PDFRamiplectrus catiensis gen. et sp. n. is characterized by the unique combination of two long metatibial spurs and a short ramus on the two first funicular segments. Phylogenetic analysis of 28SrRNA sequences, along with the distinct morphological features, supports the classification of the new genus within the tribe Eulophini.

First report of Phymatinae and Holoptilinae from the Middle East, with a description of a new species of Putoniola Bergroth (Heteroptera: Reduviidae: Holoptilinae) from Israel
No full textThis study presents the first record and a comprehensive review of the Reduviidae subfamilies Phymatinae and Holoptilinae in Israel. The paper provides updated diagnoses, detailed genitalia illustrations and a revised identification key for species of the genus Putoniola Bergroth, 1898 (Holoptilinae), along with description of a new species, Putoniola asvadurovi sp. n. The findings of Phymata (Phymata) monstrosa (Fabricius, 1794) (Phymatinae) in Israel confirm an old Middle Eastern record of the species from ‘Syria’ and considerably extend its previous West Mediterranean distribution. Information on distribution of both species and their biology and host plant associations is provided. Molecular phylogenetic analyses employing COI and 16S mitochondrial genes confirm the broad “Phymatine complex” and successfully integrate the new Putoniola species. We contribute to addressing a critical gap in knowledge of the phylogenetic relationships of tribes within the subfamilies Holoptilinae and Phymatinae, which are not yet fully understood and require further investigation. This is the first molecular study to include Phymata (P.) monstrosa (Phymatinae) and to add Putoniola asvadurovi sp. n. (Holoptilinae), both originating from the Palaearctic Region.

A new Pseudophoxinus species (Teleostei, Cypriniformes, Leuciscidae) from the upper Jordan River basin (Israel) with comments on the status of a few other congeneric species
Get PDFA taxonomic reassessment of Pseudophoxinus populations in the upper Jordan River basin has revealed that specimens previously identified as Pseudophoxinus kervillei actually represent an undescribed species. In addition, earlier taxonomic revisions have shown that P. kervillei is a junior synonym of P. libani and should no longer be regarded as a valid species. In this study, we formally describe the newly recognized species as Pseudophoxinus galilaeus sp. nov. Pseudophoxinus galilaeus sp. nov. is characterized by 39–44 scales along the mid-lateral row, 13–17 pored lateral line scales, and 20–23 predorsal scales. It has 4–5 gill rakers on the lower arch of the first gill, with two being notably short. The species possesses 33–34 vertebrae; its dorsal fin originates at vertebrae 12 or 13, and its anal fin commonly originates at vertebra 19, occasionally extending to vertebra 20 or 21. Pseudophoxinus galilaeus sp. nov. inhabits ponds, lakes, and rivers with slow to moderate currents. A unique DNA barcoding signature (mtDNA COI) revealed that it differs from any other previously bar-coded Pseudophoxinus species. In phylogenetic analyses, it clustered with the Pseudophoxinus species from neighboring countries in the Levant region, suggesting a common ancestor for these species. This analysis shows that sequences of P. kervillei from Turkey differ from P. libani from Lebanon and Syria. Further morphological examination is needed to determine the status of the species
Rediscovery of a second species of Reed Beetle in Israel (Coleoptera, Chrysomelidae, Donaciinae)
No full textA species of reed beetle, Donacia simplex (Coleoptera, Chrysomelidae, Donaciinae) was recently rediscovered in northern Israel. Now a second species, Donacia tomentosa, has been rediscovered (verified using molecular analysis) living further south in Israel. In 2021 a reed beetle expert discovered a very old record of Donacia tomentosa from modern day Israel in the collections of the Natural History Museum (London) from a few specimens collected near Tel Aviv by the British in 1918 during WWI. In 2022 the authors discovered a viable population of D. tomentosa in Israel. Given the extensive amount of collecting by many good field entomologists in that region since 1918, it is surprising that this species had not been seen for 104 years. The location, biology, molecular analysis, and other details of this newly found viable population of D. tomentosa in Israel are provided here
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
