Frons slightly broader anteriorly and gradually narrowed, dark brown with two narrow greyish-yellow pollinose vittae on lateral margins, frons-eye ratio 1:1.5. Face uniformly yellowish brown, clypus-face ratio 1:5. Parafacial brownish yellow, narrower than first flagellomere. Gena brownish yellow, gena and eye ratio 1:3. Outer side of the antennae and apical region of inner side dark brown, rest of the inner side divided with brown on the upper half and yellow on the lower half; arista microscopic pubescent basally. Head chaetotax normal but ocellar and frontoorbitals absent. Occiput dark brown. Proboscis yellowish brown; palpus brownish yellow. Thorax. Dark brown, lusturus with greyish pollinose stripe and spots. Mesonotum with a broad greyish stripe in the middle through the whole length; postnotal lobe greyish pollinose laterally with concolourous hairs. Notopleuron greyish pollinose. Anepisternum, anepimeron, katatergite, anatergite and subscutellum all grey pollinose. Scutellum concolourous with thorax bearing a pair of apical and subapical bristles. Thoracic chaetotaxy normal. Haltere yellowish white. Wings hyaline, a brown costal band extending from the base of cell Sc to apex of vein M1+2 and distinctly wide at apex between R4+5 and M1+2. Cell bc and c yellowish tinged, cell br hyaline; R-m cross vein and Dm- cu cross vein infuscated. Wing span ± 5.46 mm (Fig. 4). Legs uniformly dark brown with apex of femora yellowish, fore femur with a row of long bristles on apical half postero-ventrally and with another row antero-ventrally through whole length (Fig. 5), mid and hind femora with fine white hairs Abdomen. Yellowish brown, base of 1st tergum with dark brown infuscation which gradually narrowed to posterior margin, 2nd tergum with a dark brown median stripe, in 3rd tergum the stripe after middle widens and reaches lateral margin, 4th tergum entirely dark brown except a yellowish spot laterally at anterior margin. Male genitalia (Fig. 6 & 7): Epandrium almost rectangular in shape with surstyle projecting downwards; cerci semi-circular at apex with yellowish piles. Phallus long looped, glans bulbous shaped attached to phallus; two terminal filament arises from distal end of glans; ejaculatory apodeme funnel shaped. Variation (Paratype, female). Similar to male in general appearance, first flagellum almost uniformly dark brown; apex of all femora slightly yellowish; abdomen uniformly dark brown. Remarks. Among the five reported species from India, P. teres is closely similar to the present species P. sagarensis sp. nov. in respect of wing colouration and superficial resemblance with shape of male genitalia. The comparisons with P. teres have been made on the basis of the description of Hendel (1914) and the illustrations of wing and male genitalia provided by Wang and Chen (2006). The present species P. sagarensis is distinctly differs from P. teres by the following sets of character: shape of costal band, infuscation on R-m and Dm- cu cross vein, thorax and abdomen colouration. Apical part of costal band of P. sagarensis distinctly wider than P. teres; R-m and Dm- cu cross vein are infuscated in P. sagarensis, whereas not infuscated in P. teres. The colour of thorax and scutellum is dark brown in P. sagarensis while the thorax is reddish brown and scutellum red in P. teres. Abdominal colouration of P. sagarensis is yellowish brown but shining dark blue violet in P. teres. Etymology. The name sagarensis refers to the name of the type-locality Sagar Island, Sunderban, West Bengal. Distribution. So far reported from only type-locality, Sikarpur, Sagar Island of Sunderban, which is located in the district 24 parganas (South) of the state West Bengal, India.Published as part of Roy, Sankarsan, Parui, Panchanan & Mitra, Bulganin, 2017, Plagiostenopterina sagarensis sp. nov.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
