Elaeis guineensis (Arecaceae), Cycas siamensis (Cycadaceae). Biology. Occurring on leaves of its hosts (Tang 1991). Remarks. No specimens were available for study. This species most closely resembles, and is perhaps co-specific with C. rusci, but differs from latter in lacking a cephalic clear area.Published as part of Wu, San-An & Wang, Xubo, 2019, A review species of the genus Ceroplastes (Hemiptera: Coccomorpha: Coccidae) in China, pp. 520-536 in Zootaxa 4701 (6) on page 532, DOI: 10.11646/zootaxa.4701.6.2, http://zenodo.org/record/356257
Ceroplastes cirripediformis Comstock 1881
No full textCeroplastes cirripediformis Comstock, 1881 (Fig. 3) Ceroplastes cirripediformis Comstock, Li et al., 2018: 527. Material examined. YUNNAN: 16 ♀♀, Baoshan, on unknown plant, 6.xi.2012, coll. Xinlei Huang; 12 ♀♀, Mengzi, on Duranta repens, 17.iv.2013, coll. Jun Deng, Xubo Wang, & Xu Zhang; 28 ♀♀, Puer, on D. repens, 23–25.iv.2013, coll. Jun Deng, Xubo Wang, & Xu Zhang. Distribution in China. Fujian, Guizhou, Guangdong, Jiangxi, Sichuan, Yunnan, Zhejiang (Li et al. 2018). Host-plants. Conyaza japonica (Asteraceae); Bischofia javanica (Euphobiaceae); Cedrus deodara (Pinaceae); Pyrus sp. (Rosaceae); Hamelia patens (Rubiaceae) and Duranta repens (Verbenaceae). Among those, Duranta repens is the preferred host (Li et al. 2018). Biology. The adult females occur on the branches of the host. Remarks. This species was identified by comparison with Gimpel et al. (1974) ’s description and illustration. Ceroplastes cirripediformis differs from all other species discussed here from China in possessing clearly capitate dorsal setae. Its waxy test is similar to that of C. rusci, but C. cirripediformis can be easily distinguished from C. rusci by having an antenna with 7 segments and the dorsal pores predominantly trilocular (C. rusci has an antenna with 6 segments and the dorsal pores predominantly bilocular).Published as part of Wu, San-An & Wang, Xubo, 2019, A review species of the genus Ceroplastes (Hemiptera: Coccomorpha: Coccidae) in China, pp. 520-536 in Zootaxa 4701 (6) on page 524, DOI: 10.11646/zootaxa.4701.6.2, http://zenodo.org/record/356257

Mangifera indica (Anacardiaceae); Schefflera octophylla (Araliaceae); Diospyros discolor (Ebenaceae); Garcinia subelliptica (Guttiferae); Syzygium samarangense (Myrtaceae); Palaquium formosanum (Sapotaceae) (Fang 1989; Tao et al. 1983). Biology. Both immature and mature stages live on the lower surfaces of the host-plant. Remarks. This species was first recorded from Taiwan by Takahashi (1929) on Mangifera indica, and from Yunnan by Deng et al. (2014) on Schefflera octophylla and M. indica. It can be easily distinguished from other Ceroplastes species by the wax cover of the adult female resembling a starfish, and by having 7–11 pairs of setae between the antennae.Published as part of Wu, San-An & Wang, Xubo, 2019, A review species of the genus Ceroplastes (Hemiptera: Coccomorpha: Coccidae) in China, pp. 520-536 in Zootaxa 4701 (6) on page 532, DOI: 10.11646/zootaxa.4701.6.2, http://zenodo.org/record/356257
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

Xiaoxiao Wang; 3 ♀♀, Zhoushan: on Ilex cornuta, 15.xi.2005, coll. Saijun Yang. Distribution in China. Widely distributed in southern parts of China outdoors and it also occurs indoors in northern China; the highest populations are found in East, Central and Southwest China. Host-plants. Ceroplastes rubens is a polyphagous species. In China, it can infest over 40 plant species belonging to 24 families; preferred hosts include: Camellia spp., Cedrus deodara, Cinnamomum spp., Citrus spp., Ilex cornuta, Magnolia spp., and Pinus spp. (Wang 2001). Biology. In China, this species reproduces sexually, has one generation per year and overwinters as mated adult females. The females mainly feed on the stem, branches and upper leaf surfaces, whereas the males feed on the petioles and lower leaf surfaces. Once the crawler has settled, the remaining instars develop in the same spot (Zeng & He 1939; Tao et al. 2003; Xia et al. 2005; Huang et al. 2007). Remarks. Ceroplastes rubens can easily be distinguished from the other Ceroplastes species in China by the appearance of its wax cover, and by the adult female having reduced and distorted legs.Published as part of Wu, San-An & Wang, Xubo, 2019, A review species of the genus Ceroplastes (Hemiptera: Coccomorpha: Coccidae) in China, pp. 520-536 in Zootaxa 4701 (6) on page 531, DOI: 10.11646/zootaxa.4701.6.2, http://zenodo.org/record/356257
