查看更多>>摘要：A new genus and species of Asian green pitviper is described from Southwest China based on two female specimens. A new DNA phylogeny recovers the two specimens of the new species as a well-supported clade that is sister group to all sampled representatives of the genera Viridovipera and Cryptelytrops. The new genus is distinguished from other pitviper genera by a combination of morphological characters, including the absence of a lateral stripe, large body size, and deep red eye in adult females. Morphologically the new species is superficially most similar to species of Popeia in body dimension and scalation, but is genetically extremely distinct. The new genus/species is currently known only from south Sichuan, where it was found at about 1000 m above sea level in less disturbed evergreen rainforest.

Here, three new species of Bradyfallotaspis Fritz, 1972 (B. coriae, B. nicolascagei, and B. sekwiensis) and one new species of Nevadia Walcott, 1910 (N. saupeae) are described from the Sekwi Formation of the Mackenzie Mountains, Northwest Territories, Canada. In addition, new specimens potentially referable to Nevadia ovalis McMenamin, 1987 were recovered that may expand that species' geographic range, which was thought to be restricted to Sonora, Mexico. The results of a phylogenetic analysis incorporating several olenelline taxa, including Judomia absita Fritz, 1973 from the Sekwi Formation, are also presented herein. This species has been assigned to various olenelline genera, including Judomia Lermontova, 1951 and Paranevadella Palmer & Repina, 1993. Phylogenetic analysis suggests this species is closely related to Judomia tera Lazarenko, 1960 from Siberia. This phylogenetic relationship provides further support for the hypothesis that a close biogeographic relationship existed between Laurentia and Siberia during the Cambrian.

Milne-Edwards, 1870, is described based on a single female specimen collected from a submarine cave at Ie Island, Ryukyu Islands, Japan. The new species can be easily distinguished from all five congeners by its proportionally longer pereopods as well as by combinations of the characters of the carapace, eyes, and cheliped.

The lack of skull and original collecting data does not allow the gathering of firm evidences about its taxonomic relationships, geographical range and ecological preferences. This taxon is provisionally allocated to the recently created genus Fukomys Kock, Ingram, Frabotta, Honeycutt and Burda 2006 on the grounds of pelage colour pattern and geographical origin. All the available evidence, including label and other fragmentary historical data, supports Fukomys ilariae sp. nov. as originating from the Lower Shebelle region near Mogadishu, Somalia, historically known as Benadir. This discovery highlights the relevance for biodiversity conservation of the Horn of Africa and the need of further faunistic research to describe its fauna.

Amphiglossus meva n. sp. is characterized and differentiated from other species of the genus by a combination of morphological, chromatic and molecular characters: 1) a relatively large size (SVL of adults from 126 to 150 mm); 2) a characteristic pattern of coloration, Amphiglossus meva being the only skink in Madagascar together with Amphiglossus crenni with dark grey dorsum contrasting with orange flanks and ventrum; 3) the absence of a postnasal scale; 4) the presubocular frequently absent, 5) the presence of single elongated tertiary temporal bordering lower secondary temporal and 6) pentadactyl limbs. In addition to the morphological approach, a multi-locus genetic analysis based on eight mitochondrial and nuclear genes clearly supports the distinctiveness of A. meva. This new species was found in areas of rainforest, sometimes containing transitional deciduous forest elements. It was typically observed under large rotten logs associated with dense layers of decomposed wood retaining certain humidity and providing habitat for invertebrate larvae and termites.
查看更多>>摘要：While discussing the problems related to multiple original spellings or symprotographs (Dubois 2010: 14) of nomina in zootaxonomy, David et al. (2009: 5) stated that one of the generic bird nomina created by Vieillot (1816) had been so under two different spellings: Thriothorus (p. 45) and Thryothorus (p. 70). They pointed to the fact that subsequently Vieillot (1819: 55) had only used the spelling Thryothorus for this nomen, and thus had acted as a first-reviser between the two spellings under the new Rule introduced in Article 24.2.4 of the last edition of the Code (Anonymous 1999), a nomenclatural act designated by Dubois (2010: 15) as an internal first-reviser action or IFRA.
