| 1 | Two new species of Japalura(Squamata:Agamidae)from the Hengduan Mountain Range,China显示文摘Until recently,the agamid species,Japalura flaviceps,was recognized to have the widest geographic distribution among members of the genus occurring in China,from eastern Tibet to Shaanxi Province.However,recent studies restricted the distribution of J.flaviceps to the Dadu River valley only in northwestern Sichuan Province,suggesting that records of J.flaviceps outside the Dadu River valley likely represent undescribed diversity.During two herpetofaunal surveys in 2013 and 2015,eight and 12 specimens of lizards of the genus Japalura were collected from the upper Nujiang(=Salween)Valley in eastern Tibet,China,and upper Lancang(=Mekong)Valley in northwestern Yunnan,China,respectively.These specimens display a unique suite of diagnostic morphological characters.Our robust comparisons of phenotype reveal that these populations can be distinguished readily from J.flaviceps and all other recognized congeners.Herein,we describe the two Japalura lineages as new species,Japalura laeviventris sp.nov.and Japalura iadina sp.nov..In addition,we provide updated conservation assessments for the new species as well as imperiled congeners according to the IUCN criteria for classification,discuss the importance of color patterns in the diagnosis and description of species in the genus Japalura,and discuss directions for future taxonomic studies of the group. | Kai WANG Ke JIANG Da-Hu ZOU Fang YAN Cameron D.SILER Jing CHE Kunming Institute of Zoology,Chinese Academy of Sciences Sam Noble Oklahoma Museum of Natural History and Department of Biology,University of Oklahoma Tibet University | 2016 | Zoological Research2016，37，1： | 9 |
| 2 | Amphibians and Reptiles of Luzon Island,V:The Herpetofauna of Angat Dam Watershed,Bulacan Province,Luzon Island,Philippines显示文摘We report amphibian and reptile distribution records based on recent biodiversity surveys conducted at the Angat Watershed Reservation,Bulacan Province,Luzon Island,Philippines.This watershed constitutes the principal water source for Manila,the Philippines’largest metropolitan area.As virtually nothing is known of the herpetological diversity of the immediate area and the surrounding Bulacan Province,all species recorded as part of our surveys constitute major geographical records and/or significant range extensions.Our data result in a total of 63 new records of amphibian(19 frogs)and reptile(22 lizards,2 turtles,and 20 snakes)species for this protected area(and immediate vicinity)that serves as a watershed for the major metropolitan area of Manila and surrounding cities.Together with the few previous literature records,our new records bring the total number of amphibian and reptile species for Bulacan Province to 68.We discuss several strategies for future survey work(focusing on habitat type,seasonal variation,and elevational variability)that we anticipate will result in increased knowledge of diversity within the Angat Watershed Reserve.The impressive level of herpetological diversity within such a small area,so close to Metro Manila,emphasizes that the diversity and distribution patterns of amphibians and reptiles from Luzon are still poorly known and in need of further study. | David S.MCLEOD Cameron D.SILER Arvin C.DIESMOS Mae L.DIESMOS Vhon S.GARCIA Angela O.ARKONCEO Kelvin L.BALAQUIT Charlene C.UY Mariden M.VILLASERAN Earle C.YARRA Rafe M.BROWN | 2011 | Asian Herpetological Research2011，2，4： | 4 |
| 3 | A New Species of Japalura (Squamata: Sauria:Agamidae) from Upper Lancang (Mekong) Valley of Eastern Tibet, China显示文摘A new species of the agamid genus Japalura is described based on 15 specimens from the upper Lancang(Mekong) Valley of eastern Tibet, PR China. Populations of the new species, Japalura vela sp. nov., were previously recognized as J. flaviceps. The new species is morphologically most similar to J. batangensis, J. micangshanensis, J. variegata, and J. zhaoermii, but is distinguished from the four species and all remaining congeners by the following combination of morphological characters: 1) small adult size(SVL 56–69 mm in males, 59–66 mm in females); 2) ratio of tail TAL/SVL 1.85–2.06; 3) ratio of hind limb HLL/SVL 0.72–0.81; 4) T4 S 24 or 25; 5) concealed tympanum; 6) transverse gular fold present; 7) gular pouch present; 8) axillary fold present; 9) a pronounced, continuous, sail-like vertebral crest along length of body in males; 10) ground dorsal coloration black in males; 11) distinct gray transverse streaks on dorsal surface of head; 12) black radiated streaks around eyes; 13) distinct, black vermiculate stripes on ventral surface of head in both sexes; 14) a strongly jagged dorsolateral stripe from neck to base of tail on each side of vertebral crest in males; and 15) absence of gular spots in both sexes. General distribution patterns of the genus in the Hengduan Mountains region are also discussed. | Kai WANG Ke JIANG Gang PAN Mian HOU Cameron D.SILER Jing CHE | 2015 | Asian Herpetological Research2015，6，3： | 2 |
| 4 | Phylogenetic Patterns of the Southeast Asian Tree Frog Chiromantis hansenae in Thailand显示文摘Although landscape features such as mountains and rivers are recognized often as limiting factors to amphibian dispersal and gene flow, a limited number of studies have investigated such patterns across Southeast Asia. A perfect example of this is Thailand, located in one of the world's biodiversity hotspot regions. Thailand represents the corridor between mainland Asia and the Sunda Shelf, a famous and widely recognized biogeographic region, and yet there are few studies on the genetic structure among populations of amphibian species distributed across Thailand. The Southeast Asian tree frog, Chiromantis hansenae has been reported to possess a geographic range that is restricted to Thailand and, presumably, Cambodia. Here, we investigate phylogenetic relationships among C. hansenae populations using partial sequences of the mitochondrial 16 S rRNA gene and nuclear POMC gene. Our results reveal two distinct evolutionary lineages within C. hansenae populations in Thailand. The genetic divergence among populations between these two clades is considerable, and results support inter-population divergence, and high genetic differentiation(pairwise FST = 0.97), between two localities sampled in western Thailand(TK1 and TK2), separated from each other by 40 kilometers only. The results suggest that landscape features across Thailand may have a profound impact on patterns of diversification in the country, underscoring the urgent need for fine-scale investigations of genetic structure of endemic and 'widespread' species. | Siriporn YODTHONG Cameron D.SILER Pongpun PRASANKOK Anchalee AOWPHOL | 2014 | Asian Herpetological Research2014，5，3： | 1 |
