Thelepus Leuckart 1849
No full textGenus Thelepus Leuckart, 1849 Type species. Thelepus cincinnataus (Fabricius, 1780) Remarks. Forty-six species are currently included in the genus, including forty-three species listed in Read (2016b) and three new combination species, Thelepus abranchiatus (Hartman & Fauchald, 1971), Thelepus malayensis (Caullery, 1944), and Thelepus verrilli (Treadwell, 1911), as suggested by Hutchings & Glasby (1987) and Londoño-Mesa (2009). Of those forty-six species, only Thelepus plagiostoma (Schmarda, 1861), Thelepus opimus Hutchings, 1990, and Thelepus pulvinus Hutchings, 1990 have been reported from the East China Sea and Hong Kong (Yang & Sun 1988; Hutchings 1990), and none have been reported from Taiwanese waters. The present study adds two more species to the genus.Published as part of Hsueh, Pan-Wen & Li, Kuo-Rong, 2016, New species of Thelepodidae (Terebelliformia, Polychaeta) from Taiwan, pp. 510-524 in Zootaxa 4170 (3) on page 516, DOI: 10.11646/zootaxa.4170.3.5, http://zenodo.org/record/26443

The present study therefore increases the number of known species for this genus to 52. Of these, only five were previously recorded from Chinese waters, including the two described in this paper.</p>Published as part of <i>Hsueh, Pan-Wen & Li, Kuo-Rong, 2017, Additions of new species to Thelepus (Thelepodidae), with description of a new Terebellides (Trichobranchidae) from Taiwan, pp. 429-439 in Zootaxa 4244 (3)</i> on page 430, DOI: 10.11646/zootaxa.4244.3.10, <a href="http://zenodo.org/record/432117">http://zenodo.org/record/432117</a>
Terebellides Sars 1935
No full textGenus <i>Terebellides</i> Sars, 1935 <p> Type species. <i>Terebellides stroemii</i> Sars, 1835 <b>Remarks.</b> Members of <i>Terebellides</i> are characterised by having fused branchial stems and multi-lobed branchiae with transverse lamellae on mid-dorsum, 18 thoracic chaetigers, first neuropodia with geniculate hooks and subsequent ones with denticulate hooks (Hutchings & Peart 2000; Schüller & Hutchings 2013; Hutchings <i>et al</i>. 2015). Hutchings & Peart (2000) emended the generic diagnosis given in Holthe (1986) by including the presence of ornamented notochaetae and the variation in the number of branchial lobes and their relative development. Schüller & Hutchings (2013) added a morphologic feature to the generic diagnosis, the presence of two segments with geniculate hooks, which is found in <i>Terebellides crux</i> Schüller & Hutchings, 2013. In the present study, all specimens examined showed various degree of proboscis protrusion. Yet, this observation might raise a question on whether having protruded proboscis of the present species is a stable morphological character. We are not firmly sure about the stability of this morphological character. Therefore, we tend to agree with Hutching & Peart (2000), who stated “ <i>The retractile nature of the proboscis has not previously been recorded and as this is used as a defining character for the genus, a specimen with a fully retractable proboscis could be difficult to identify</i> ”, and make no attempt to include the presence of eversible proboscis in generic diagnosis for <i>Terebellides</i> in the present study.</p> <p> To date, the genus has 55 valid species, including five recently describes species: <i>Terebellides akares</i> Hutchings, Nogueira & Carrerette, 2015, <i>Terebellides mediterranea</i> Parapar, Mikac & Fiege, 2013, <i>Terebellides hutchingsae</i> Parapar, Moreira & Martin, 2016, <i>Terebellides persiae</i> Parapar, Moreira, Gil & Martin, 2016, and <i>Terebellides shetlandica</i> Parapar, Moreira & O'Reilly, 2016 (Schüller & Hutchings 2013, Hutchings <i>et al</i>. 2015 & Parapar <i>et al</i>. 2016a, b, c). The present study adds one more species to the genus.</p>Published as part of <i>Hsueh, Pan-Wen & Li, Kuo-Rong, 2017, Additions of new species to Thelepus (Thelepodidae), with description of a new Terebellides (Trichobranchidae) from Taiwan, pp. 429-439 in Zootaxa 4244 (3)</i> on pages 433-435, DOI: 10.11646/zootaxa.4244.3.10, <a href="http://zenodo.org/record/432117">http://zenodo.org/record/432117</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
