[All data transcribed from Chinese.] Redescription FORM AND COLOUR. Length 3.6–4.3 mm, width 1.9–2.2 mm, oval, moderately convex. Head black, yellowish brown laterally (Figs 12–14); pronotum and elytra dark brown to black, both with yellowish or reddish brown margin laterally (Fig. 11); maxillary palps uniform yellow or yellowish brown (Figs 13–14); labial palps yellow, antenna yellowish brown. Ventral side dark brown to black (Fig. 10); legs dark with yellowish tarsomeres (Fig. 11). HEAD. Labrum with fine and dense punctures, smooth between punctures, anterior margin broadly emarginate. Clypeus broad, anterior margin clearly broadly emarginate, moderately expanded in front of eyes, lateral margin somewhat rounded, clearly impressed in front of eyes (Figs 12–14). Punctures on clypeus coarser and sparser than those on labrum, smooth between punctures, systematic punctures almost of same size as ground punctures (Fig. 14). Eyes of moderate size, clearly emarginate anteriorly (Figs 12–14), separated by ca 4.0× the width of one eye. Ground punctures on frons similar to those on clypeus, with clear systematic punctures in front of eyes. Maxillary palps long and slender, ca 1.2× as wide as head, second and third palpomeres curved inwards, apical palpomere almost as long as penultimate, asymmetrical (Fig. 16). Antennae with 9 antennomeres, scape ca 1.5× as long as pedicel, pedicel subequal in length to antennomeres 3–6 combined, club loosely with dense pubescence. Mentum ca as wide as long, subquadrate, with strong v-shaped impression anteromedially, with coarse punctures and wrinkles posteriorly (Fig. 16). Submentum with a small glabrous area medially and with a few coarse punctures laterally. Maxilla with coarse punctures, smooth between punctures. THORAX. Pronotum ca 2× as wide as long, widest posteriorly, posterolateral margins broadly round, anterior margin smooth, with a very fine transverse groove, lateral margin with stronger groove, posterior margin without such groove; posterior margin almost straight. Ground punctures on pronotum slightly coarser than on head, with distinct setiferous systematic punctures (Fig. 13). Prosternum bulging in middle, not carinate, pubescent, with transverse groove (Fig. 16), protruding anteriorly. Mesoventrite with a low transverse ridge medially, which does not bear an elevated tooth or projection but with a tuft of long setae (Fig. 15), behind ridge with a low longitudinal carina. Metaventrite pubescent, with somewhat convex middle portion, without glabrous area. Metepisterna ca 3.5× as long as wide, subparallel. Scutellum triangular, with similar punctures to elytra. Elytra with ground punctures similar to those on pronotum and with 3 distinct rows of systematic punctures (Fig. 11), without sutural stria; epipleura very broad anteriorly, reaching posterior margin of first visible abdominal sternite, with sparse, coarse punctures. Femora densely pubescent, with apical eighth glabrous (Figs 10, 17). Metatarsomeres with dense white hairs ventrally and some long swimming hairs dorsally. Claws of moderate size, rather strongly curved. ABDOMEN. All visible abdominal ventrites with dense pubescence; first ventrite not carinate (Fig. 17). AEDEAGUS. Broad, paramere ca 6.5× as long as width of apex, subparallel, slightly expanded subapically and round apically, apex without small, inwardly directed tooth; median lobe somewhat expanded subapically, abruptly narrowed apically (Fig. 47). Differential diagnosis This species is closest to H. songi sp. nov., from which it can easily be distinguished by its smaller size; clypeus yellowish brown laterally (Fig. 12–14); elytra with yellowish or reddish brown margin laterally (Fig. 11); maxillary palps uniform yellow or yellowish brown (Figs 13–14); pronotum and elytra more finely punctate; parameres ca 6.5× as long as width of apex, apex without a small, inwardly directed tooth (Fig. 47). Biology This species occurs in small stagnant pools and on wet stones on ground with grass or leaf litter near rivers or streams, but never collected in habitats where Oocyclus spp. occur. It is occasionally collected at light. The female carries the egg case under the abdominal ventrites. Distribution China (Fujian, Guangdong, Guangxi, Hong Kong, Macau), Cambodia, Indonesia (Java, Sumatra), Malaysia (peninsula) (Hansen 1999).

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
