No full textTylomelania hannelorae sp. nov. Type material. Indonesia, Sulawesi, Lake Mahalona, loc. 56 -03: Holotype (Fig. 6 A; 11.8 mm x 5.5 mm), MZB Gst. 12.114; paratypes (Fig. 6 B), MZB Gst. 12.115, n= 3; ZMB Moll. 190713, n= 5. Etymology. The new species has been named hannelorae in honour of Hannelore Glaubrecht, for her emotional participation in our Sulawesi research. Description. Shell (Fig. 6 A,B): Small, dark brown, elongate conic, spire angle 11–17 °. Top whorls in adult specimens always corroded to a varying degree, 3–5 remaining whorls, can reach up to 13.9 mm (Tab. 2). Axial and spiral ribs form reticulated pattern. Aperture oval, pointed at top and slightly siphonated at base. Columella and interior dark brown. External morphology: Headfoot black, mantle edge serrated to a varying degree. Operculum (Fig. 6 C): ovate, last whorl strongly inflated, multispiral with 10 whorls. Radula (Fig. 6 D,E): 28–44 rows, 2.1–3.2 mm long, on average 13.7 teeth per mm (n= 5). Central tooth with very large and elongate squarish major denticle and one minor denticle on each side. Glabella narrow, with convex base. Lateral teeth with very much enlarged squarish major denticles and one minor denticle on each side. Marginal teeth shovel-like, inner and outer marginals with three denticles each, the outermost ones considerably wider than the inner ones. Reproductive biology: Brood pouch contains 1–2 embryos, their size can reach 3.1 mm (Tab. 3). Embryonic shells (Fig. 6 F–H): Ovate-conic, with strong axial ribs emerging on the 2 nd to 3 rd whorl and fading on the 5 th whorl. Shallow, widely spaced spiral ribs emerge on 3 rd to 4 th whorl (Tab. 3). Distribution and habitat. South Sulawesi, Lake Mahalona, cape on NW shore (Fig. 1 B). This species was collected on rocks in shallow water (less than 0.5 m depth). Taxonomic remarks. T. hannelorae is the smallest species within the Malili lakes species flock. Its size in combination with the reticulate shell sculpture generally can serve to distinguish it unambiguously from all other species in the system. While T. hannelorae might be mistaken for subadult specimens of T. confusa Rintelen, Bouchet & Glaubrecht, 2007, at first glance, the shell corrosion of the upper whorls characteristic for older animals will allow identifying any specimen as a fully grown adult. Molecular phylogeny. The topology of the 16 S ML phylogram based on 851 bp of mitochondrial 16 S rDNA (Fig. 7) is basically identical to the tree presented in Rintelen et al. (2004) except for the inclusion of two of the new species described here, T. baskasti and T. sinabartfeldi (all attempts to sequence T. hannelorae failed). Both species belong to a clade of smooth-shelled or spirally-ribbed taxa (clade Malili 2, compare Rintelen et al. 2004, 2007), where they form a poorly supported subclade which is sistergroup to all remaining species of clade Malili 2 but for one individual of T. sarasinorum (Kruimel, 1913) from the outlet bay of Lake Towuti clustering with T. baskasti and T. sinabartfeldi. While the three haplotypes of T. sinabartfeldi are identical, T. baskasti appears paraphyletic with an intraspecific sequence divergence of 0.6 % (p-distance).Published as part of Rintelen, Thomas Von & Glaubrecht, Matthias, 2008, Three new species of the freshwater snail genus Tylomelania (Caenogastropoda: Pachychilidae) from the Malili lake system, Sulawesi, Indonesia, pp. 37-49 in Zootaxa 1852 on page 46, DOI: 10.5281/zenodo.18342
A new genus of river snails, <i>Bakyietaia</i> (Mollusca, Viviparidae), from South China and the Indochinese Peninsula
No full textA new genus of the river snail family Viviparidae, Bakyietaia Zhang, Yen & von Rintelen gen. nov., is described based on a comprehensive study of its morphology, anatomy, mtDNA (COI), ecology and distribution. This genus is widely distributed in South China and the Indochinese Peninsula. It can be distinguished from all other viviparid genera, especially Angulyagra, Sinotaia and Anulotaia, by characters of the columellar lip of the shell, the operculum and the marginal teeth of radula. Based on an integrative taxonomic approach, 17 species are assigned to this new genus and described here, including 7 new combinations and 10 new species: Bakyietaia subcostata gen. et comb. nov., B. polyzonata gen. et comb. nov., B. boettgeri gen. et comb. nov., B. duchieri gen. et comb. nov., B. guangdungensis gen. et comb. nov., B. mutica gen. et comb. nov., B. wilhelmi gen. et comb. nov., B. chenghuang Zhang, Yen & von Rintelen gen. et sp. nov., B. jingweiae Yen, Zhang & von Rintelen gen. et sp. nov., B. liusanjieae Zhang, Yen & von Rintelen gen. et sp. nov., B. avisvenatoris Yen, Zhang & von Rintelen gen. et sp. nov., B. liangzhuorum Yen, Zhang & von Rintelen gen. et sp. nov., B. luikongi Yen, Zhang & von Rintelen gen. et sp. nov., B. fontinalis Zhang, Yen & von Rintelen gen. et sp. nov., B. naiadica Zhang, Yen & von Rintelen gen. et sp. nov., B. luuemxlong Zhang, Yen & von Rintelen gen. et sp. nov. and B. indrapura Zhang, Yen & von Rintelen gen. et sp. nov. The monophyly of all morphospecies is supported by the COI phylogeny. Radular characters, especially the number of cusps of the outer marginal teeth, are considered valuable in the classification of species of Bakyietaia with similar shells.</p
Tylomelania baskasti Rintelen & Glaubrecht, 2008, sp. nov.

Indonesia, Sulawesi, Larona River: Holotype (Fig. 2 A; 52.3 mm x 17.7 mm, loc. 71 -02), MZB Gst. 12.109; paratypes (Fig. 2 B-D): loc. 14 –02, MZB Gst. 12.110, n= 5; ZMB Moll. 190533, n= 7; loc. 15 -02, MZB Gst. 12.111, n= 12; ZMB Moll. 190534, n= 16; loc. 71 -02, MZB Gst. 12.112, n= 14; ZMB Moll. 190535, n= 17. Etymology. The new species has been named baskasti in honour of Bas Kast, who has generously supported research on these snails at the Museum für Naturkunde. Description. Shell (Fig. 2 A–D): Medium sized to large, brown, elongate conic, spire angle 13–25 °. Top whorls in adult specimens always corroded to a varying degree, 4–9 remaining whorls, can reach up to 54.7 mm (Tab. 1). With spiral ribs only. Aperture oval, pointed at top and slightly siphonated at base. Columella and interior of aperture brown, in few specimens slightly whitish coating. External morphology: Headfoot black with fine orange dots, sometimes rather dense, foot more intensely pigmented, mantle edge serrated to a varying degree. Body coiled in 3–6 whorls. Operculum (Fig. 2 E,F): roundish-ovate, last whorl inflated, multispiral with 5–7 whorls (n= 3). Radula (Fig. 3 A,B): 160–194 rows, 16.4–24.2 mm long, on average 8.8 teeth per mm (n= 12). Central tooth with pointed and enlarged major denticle. Glabella with very slightly rounded base. Lateral teeth with pointed and enlarged major denticles and 2–3 minor denticles on each side. Marginal teeth shovel-like, inner and outer marginals with three almost equal-sized denticles each. Reproductive biology: Brood pouch contains 4–12 embryos, their size can reach 8.4 mm (n= 5) (Tab. 3). Embryonic shells (Fig. 3 C–E): Elongate-conic, axial ribs emerging on the 2 nd to 3 rd whorl and fading on the 5 th whorl. Spiral striae emerge on 3 rd to 4 th whorl (Tab. 3). Distribution and habitat. South Sulawesi, lower reaches of Larona River (Fig. 1 B). This species was collected in shallow water (0.1–0.5 m depth) in less turbulent zones at the river bank on soft substrate. As deeper parts of the river were not accessible for sampling because of strong currents, T. baskasti must not necessarily be restricted to shallow water. Taxonomic remarks. Shell shape and radula of T. baskasti are similar to that of T. lalemae (Kruimel, 1913) from Lake Towuti. The shell of T. baskasti is more fragile and always lacks the conspicuous white aperture of T. lalemae, though. The radula of T. baskasti also closely resembles that of all other described riverine species of Sulawesi such as e.g. T. perfecta (Mousson, 1849). T. baskasti can be unambiguously distinguished from those taxa by its characteristic shell and the molecular data clearly confirm its relationship to the Malili lakes species flock (compare also below, Discussion).Published as part of Rintelen, Thomas Von & Glaubrecht, Matthias, 2008, Three new species of the freshwater snail genus Tylomelania (Caenogastropoda: Pachychilidae) from the Malili lake system, Sulawesi, Indonesia, pp. 37-49 in Zootaxa 1852 on pages 39-41, DOI: 10.5281/zenodo.18342

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

Faint reddish lines on posterior margin of first and anterior margin of third to fifth abdominal pleura.</p> <p> <b>Etymology.</b> The new species is named after its type locality – Buton Island, Indonesia.</p> <p> <b>Remarks.</b> <i>Caridina butonensis</i> n. sp. is close to <i>C. opaensis</i> in term of the morphology of the chelipeds, the pereiopods and the male sexual appendages. The new species can be distinguished from <i>C. opaensis</i> by its short and truncated rostrum lacking postorbital teeth (vs. rostrum slender, pointed, with 3–7 postorbital teeth in <i>C. opaensis</i>), its small antennal spine fused with inferior orbital angle (vs. distinct, situated below inferior orbital angle in <i>C. opaensis</i>), its relatively short penultimate segment of third maxilliped (penultimate as long as ultimate vs. penultimate longer than ultimate in <i>C. opaensis</i>), no epipod on the third up to the fifth pereiopods (vs. reduced epipod on the third pereiopod in <i>C. opaensis</i>), and its smaller size (2.18–3.79 mm carapace length vs. 3.06–4.54 mm carapace length in <i>C. opaensis</i>). <i>Caridina butonensis</i> n. sp resembles also <i>C. boehmei</i> n. sp in cheliped morphology and reduced epipodial apparatus, however, it can be distinguished by the more reduced podobranch on the second maxilliped which becomes a lamina with some finger-like projections as in <i>C. boehmei</i> n. sp.. Further, the two species can easily be differentiated by the rostrum shape (distal conspicuous truncated vs. pointed in <i>C. boehmei</i>) and the rostrum formula (0 + 3–9(4–7) / 1–8(3–6) vs. 0 + 0–2(0–1) / 0–2(0–1)). The truncated rostrum of <i>C. butonensis</i> n. sp. resembles of <i>C. subventralis</i> Richard & Clark 2005 described from Lake Bunyonyi, Uganda, East Africa. However, the new species differs by the epipodial formula (well developed epipods on pereiopods 1 and 2 vs. well developed epipods on pereiopod 1 to 4 in <i>C. subventralis</i>), and the development of the podobranch on the second maxiliped (reduced to a lamella vs. well developed in <i>C. subventralis</i>). Further, the distal margin of the telson is armed with 7–8 long spines (vs. 2–3 pairs of rather stout spines in <i>C. subventralis</i>).</p> <p> <b>Distribution and habitat.</b> <i>Caridina butonensis</i> n. sp. was found in small streams on Buton Island.</p>Published as part of <i>Klotz, Werner & Rintelen, Kristina Von, 2013, Three new species of Caridina (Decapoda: Atyidae) from Central Sulawesi and Buton Island, Indonesia, and a checklist of the islands' endemic species, pp. 554-570 in Zootaxa 3664 (4)</i> on pages 564-568, DOI: 10.11646/zootaxa.3664.4.8, <a href="http://zenodo.org/record/215621">http://zenodo.org/record/215621</a>
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
