查看更多>>摘要：This paper deals with three nomenclatural and taxonomic problems affecting two species groups of the colubrid snake genus Oligodon Fitzinger, 1826: (i) A neotype is formally designated for Coronella cyclura Cantor, 1839, associating this specific nomen with populations from India, Bangladesh and Myanmar with 19 scale rows at midbody; (ii) Oligodon khe-riensis Acharji & Ray, 1936 is shown to be a valid species of the Oligodon cyclurus group occurring in northern India and Nepal; (iii) The type-locality of Simotes multifasciatusJan & Sordelli, 1865 is shown to be Sultanpur, India. This taxon is considered a synonym of Oligodon cinereus (Giinther, 1864). The range of this species in India is extended. The status of specimens of Oligodon cinereus from India and Myanmar is briefly discussed. Specimens from Thailand identified as Oligodon cinereus multifasciatus and Oligodon cinereus swinhonis (Giinther, 1864) are referred to Oligodon joynsoni (Smith, 1917). India is home to at least 21species of the genus Oligodon, an updated list of which is provided.
查看更多>>摘要：A list of species of Trematoda (flukes) transmitted by Melanoides tuberculata (Miiller, 1774) is presented based on 136 articles published between 1896 and 2010. This snail species has been reported as an intermediate host for flukes belonging to 17 families, 25 genera and 37 species, including 11 trematodes reported as adults from man. The greatest proportion of the associations between M. tuberculata and flukes has been recorded in Asia and Africa; three species are considered to be invasive in theAmericas. In addition, another 81 larval trematodes found in M. tuberculata have been described under generic collective group Cercaria Miiller, 1773, but have not yet been associated with the respective adult parasites. Studies in which the larvae found in M. tuberculata have only been grouped into eight cercarian groups are also listed.

Additionally, it has the following unique combination of characters that further separates it from all congeners: a single presubocular; separated nasals; paired frontoparietals; small, widely separated prefrontals; no supranasals or postnasal; two postsupralabials; and large, posterior chinshields that contact the in-fralabials. A molecular phylogeny based on one mitochondrial and two nuclear genes from all species of Larutia from Peninsular Malaysia indicates L. penangensis sp. nov. is most basal and thatZ. seribuatensis is the sister lineage to a clade containing L. miodactyla and the sister species L. trifasciata and L. larutensis. Consistencies and inconsistencies between this phylogeny and a previously proposed morphological phylogeny are discussed.

查看更多>>摘要：Nemuroglanis furcatus is described from streams of the rio Guariba, a clear water tributary of the rio Aripuana, rio Madeira basin in Brazil. Nemuroglanis furcatus can be distinguished from its congeners by the possession of a long lateral line, reaching the middle portion of the adipose-fin base; a narrow posterior cranial fontanel (16 to 27% of its length); and the anterior border of pectoral bridge with a pointed contour. The plesiomorphic state of some of the synapomorphies for Nemuroglanis in N.furcatus suggests that this species might be the sister-group to the remaining species of the genus. A key for all four valid species of Nemuroglanis species is provided.
查看更多>>摘要：Two species of the genus Pungentus originally described by Thorne and Swanger (1936), namely P. intertextus and P. tex-tilis, are re-described on studying type material. Both species are very similar morphologically and characterized by having large general size (body 3.7-5.1 mm long), odontostyle comparatively long (about twice the lip region width) and slender, with small aperture, relatively short neck (6-ratio = 7.0-9.0), rounded conoid tail, and slightly irregularly spaced ventromedian supplements which lack hiatus. This morphological pattern significantly differs from that found in other Pungentus species, and hence a new genus Stenodorylaimus is proposed to accommodate the two species herein studied. Descriptions, measurements, line illustrations and LM pictures are provided for both species. The new genus is compared in detail with its closest relatives.
查看更多>>摘要：A new species of spider crab, Hemus magalae n. sp. (Majidae), is described from a single male specimen from Islas de las Perlas, Pacific Ocean coast of Panama. This species differs from its congeners with respect to many features of the carapace including mid-line elevation and lateral dentition. Hemus A. Milne-Edwards, 1875, now includes four species, three from coastal waters of the eastern Pacific Ocean and one from shallow waters in the tropical western Atlantic Ocean. A key to the Pacific and Atlantic species of Hemus is provided.
