First Report of Dieback Caused by Lasiodiplodia pseudotheobromae on Ormosia pinnata in China
No full textSananicoccus Huang & Yan 2023, gen. nov.
No full textGenus <i>Sananicoccus</i> gen. nov. <p> Type species: <i>Sananicoccus nanophytoni</i> <b>sp. nov.</b></p> <p>Diagnosis. Body of adult female broadly oval, membranous. Antennae each with 7 segments. Legs well-developed, claw with a denticle. Anal ring situated at apex of abdomen, bearing 6 setae. Both ostiole pairs and circulus absent. Cerarii numbering 18 pairs, each usually with 1 or 2 conical setae and 1 or 2 trilocular pores. Dorsal setae minute, conical; ventral setae flagellate. Dorsum with large tubular ducts, each usually with 2 discoidal pores situated next to orifice. Multilocular pores and quinquelocular pores restricted to venter only; trilocular pores present on dorsum only. Oral collar tubular ducts present on both surfaces.</p> <p>Etymology. The new genus is dedicated to Dr. San’an Wu, who has made significant contributions to coccoid fauna of China.</p> <p> Remarks. The new genus is similar to the genus <i>Synacanthococcus</i> Morrison, 1920 by sharing the large dorsal tubular ducts each with discoidal pores next to the orifice and absence of anterior ostioles, but differs by <i>Synacanthococcus</i> possessing posterior ostioles and dorsal cerarii, and all cerarii, including dorsal and marginal cerarii, each situated on a prominent sclerotized area.</p> <p> The genus <i>Synacanthococcus</i> was established by Morrison (1920), with <i>S. bispinosus</i> Morrison as type species. It was once synonymized with <i>Spinococcus</i> Borchsenius, 1949 by Balachowsky (1953). Tang (1992) followed the treatment. But most researchers such as Williams (2004) considered it as a valid genus. Only 3 species of the genus were recorded till now, one from Palaearctic Region, and another two from Oriental Region.</p>Published as part of <i>Huang, Shaobin & Yan, Meiyu, 2023, A new genus and species of Phenacoccinae (Hemiptera: Coccomorpha: Pseudococcidae) from northwestern China, pp. 227-235 in Zoological Systematics 48 (3)</i> on page 228, DOI: 10.11865/zs.2023303, <a href="http://zenodo.org/record/10940835">http://zenodo.org/record/10940835</a>
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
