No full textEucreadium cameronii Gupta 1963 Synonyms: Hamacreadium manteri Gupta & Kumari, 1974 n . syn. Records. From Securicula gora (Hamilton) [as Chela gora (Hamilton)] (Cypriniformes: Cyprinidae) from Varanasi, Uttar Pradesh, India by Gupta (1963). From S. gora [as Chela gora] from Kanpur, Uttar Pradesh, India by Gupta & Govind (1983). From the large razorbelly minnow, Salmophasia bacaila (Hamilton) [as Chela bacaila (Hamilton)] (Cyprinidae) and Se. gora [as Chela gora] from Ludhiana and Rupnagar, Punjab, India by Gupta & Kumari (1974) as H. manteri. Remarks. The specimens described by Gupta & Kumari (1974) clearly do not belong in Hamacreadium because the genital pore is medial, the ovary is entire, the vitelline field reaches to the oral sucker and the hosts are freshwater fishes. The oral and ventral suckers are also of similar size, suggesting a species of Eucreadium, three species of which have been proposed from cyprinids in India: E. cameronii, Eucreadium hemlatae Gupta & Govind, 1983 and Eucreadium jhingrani Srivistava & Singh, 1967. The description of Gupta & Kumari (1974) is indistinguishable from E. cameronii and so H. manteri is synonymised with that species here.Published as part of Martin, Storm B., Cutmore, Scott C., Ward, Selina & Cribb, Thomas H., 2017, An updated concept and revised composition for Hamacreadium Linton, 1910 (Opecoelidae: Plagioporinae) clarifies a previously obscured pattern of host-specificity among species, pp. 151-187 in Zootaxa 4254 (2) on page 174, DOI: 10.11646/zootaxa.4254.2.1, http://zenodo.org/record/54586

Neolebouria leiperi Gupta 1956, n. comb.
No full text<i>Neolebouria leiperi</i> (Gupta, 1956) n. comb. <p> <b>Synonyms:</b> <i>Hamacreadium leiperi</i> Gupta, 1956.</p> <p> <b>Records.</b> From an unidentified “marine catfish” in the Gulf of Mannar by Gupta (1956).</p> <p> <b>Remarks.</b> This species was described based on two specimens and was considered a synonym of <i>H</i>. <i>mutabile</i> by Hafeezullah (1971). However, the ovary is distinctly tri-lobed, the genital pore is distinctly inter-caecal and the anterior extent of the excretory vesicle was not described. Therefore, it is consistent with the current concept of <i>Neolebouria</i>. In particular, it closely resembles species placed in the “maorum” body-type group by Dronen <i>et al</i>. (2014), which are characterised by an elongate linguiform body, a relatively small equatorial ventral sucker and a distinctly post-bifurcal and inter-caecal genital pore. One of these species, <i>N</i>. <i>capoori</i>, was also described from Indian waters, but that species is smaller (1,920–2,520 <i>vs</i> 3,500–5,500 µm long) and has larger pre-ovarian and post-testicular areas. Therefore, <i>N</i>. <i>leiperi</i> n. comb. is considered a distinct species of <i>Neolebouria</i>. Although Gupta (1956) possibly described <i>N</i>. <i>krusadaiensis</i> and <i>N</i>. <i>leiperi</i> from the same host species, perhaps even individual “catfish”, on the basis of limited material, the two appear to be distinct species because the former has a prebifurcal genital pore.</p>Published as part of <i>Martin, Storm B., Cutmore, Scott C., Ward, Selina & Cribb, Thomas H., 2017, An updated concept and revised composition for Hamacreadium Linton, 1910 (Opecoelidae: Plagioporinae) clarifies a previously obscured pattern of host-specificity among species, pp. 151-187 in Zootaxa 4254 (2)</i> on page 176, DOI: 10.11646/zootaxa.4254.2.1, <a href="http://zenodo.org/record/545862">http://zenodo.org/record/545862</a>

The transition from 3C SiC(111) to graphene captured by ultra high vacuum scanning tunneling microscopy
No full textIn this paper we clarify the transformation mechanism of 3C-SiC into graphene upon thermal decomposition, by a combination of high resolution Scanning Tunneling Microscopy (STM) images and first principle calculations. We studied the transition from 3C-SiC to graphene by high temperature annealing of C-terminated 3C SiC (1 1 1)/Si (1 1 1) samples in Ultra High Vacuum. By using STM we were able to observe very clear atomic resolution images of the transition from SiC (v33)R30࠴o a new intermediate stage SiC View the MathML source (very close to the graphene (2 נ2) reconstruction) after annealing at 1250 î We also obtained images of the transformation of the intermediate structure into a (1 נ1) monolayer graphene, caused by further sublimation of atoms in the subsurface layer. We have interpreted the results by using Density Functional Theory - Local Density Approximation calculations, which give full account of the SiC (v33)R30࠲econstruction, but fail to describe the SiC View the MathML source structure due to its incommensurability with the 3C-SiC (1 1 1) lattice.Full Tex
