巴塘攀蜥的再描述（图版封3）

1824年德国人Theodore von Vogt报道四川巴塘有云南攀蜥和草绿攀蜥,后来我国学者否定了巴塘有云南攀蜥,认为有草绿攀蜥,但这种草绿攀蜥极有可能是巴塘攀蜥。2001年李操等根据浸制标本报道了新种巴塘攀蜥（Japalura batangensis）由于其没有看到生活标本,所以在形态特征的描述上就有不足之处。2004年我们到四川甘孜州考察两栖爬行动物,8月在巴塘县竹巴笼乡采到6只巴塘攀蜥,经几个月的室内养殖观察和特征鉴定,特此再作形态和行为的补充描述。     

巴塘攀蜥冬眠的初步研究

2007年10月～2008年4月对巴塘攀蜥Japalura batangensis冬眠进行初步研究. 发现在模拟自然环境的圈养条件下,巴塘攀蜥主要选择在石缝、枯枝落叶等场所越冬.冬眠时间为当年11月中旬至翌年3月初,冬眠时全身伏贴树枝或洞壁.当室温下降至16℃左右时,巴塘攀蜥开始进入冬眠,当室温降至14℃左右时,巴塘攀蜥完全进入冬眠.翌年2～3月当室温回升至14℃左右时,巴塘攀蜥开始出眠,出眠初期活动量较小;当气温升至17℃时,巴塘攀蜥完全苏醒,活动恢复正常.

丽纹攀蜥头体大小的两性异形和繁殖期的生长

测定了丽纹攀蜥的体长、头长、头宽、头高、尾长和体重等形态指标,以及通过44天的生长后体长、头长、头宽和头高的增长。表明成年两性个体体长无显著的两性异形,局部形态特征皆与体长呈正相关。协方差分析表明,雄性的头长、头宽、头高和尾长显著大于雌性个体,繁殖期雌性个体的体重显著大于雄性个体。丽纹攀蜥繁殖期雄性体长的增长显著大于雌性体长的增长,雌雄两性头长、头宽和头高的增长无显著的差异。

甘肃省鬣蜥科一新纪录--米仓山攀蜥

米仓山攀蜥(Ｊａｐａｌｕｒａｍｉｃａｎｇｓｈａｎｅｎｓｉｓ)是宋鸣涛(1987)依据1982年在陕西省宁强县青木川所采标本描述的种。目前仅知分布于陕西南部地区。作者1999年6～7月在甘肃省陇南地区进行野外考察,先后于6月10日～6月14日、7月9日～17日在文县刘家坪、康县阳坝和文县碧口采到鬣蜥科龙蜥属标本22号,经鉴定为米仓山攀蜥,为甘肃省新纪录。米仓山攀蜥与草绿攀蜥(ＪａｐｌａｌｕｒａｆｌａｖｉｃｅｐｓＢａｒｂｏｕｒａｎｄＤｕｎｎ)相近似。区别是前者没有喉褶;上唇鳞7～8枚,下唇鳞8～9枚;尾长为头体长的两倍(个别超出两倍)。草绿攀…

A New Species of Japalura(Agamidae: Lacertilia: Reptilia) from Central Highland,Vietnam

A new species of the agamid genus Japalura is described based on three specimens from southern part of Central Vietnam.It is distinguished from remaining congeners by the following combination of characters: adult size(SVL females 68–69 mm),tail length/SVL ratio 226%–239%,HW/SVL ratio 17%–18%; FLL/SVL ratio 41%–43%; HLL/SVL ratio 72%–73%; 7–9 supralabials,7–9 infralabials,54–56 middorsal scales,20–22 lamellae under finger IV,24–26 lamellae under toe IV,1 scale between nasal and supralabials; tympanum concealed; absence of transverse gular fold.The geographical distribution of Japalura genus in general and of a new species in particular is discussed.     

A New Species of Japalura (Squamata: Sauria:Agamidae) from Upper Lancang (Mekong) Valley of Eastern Tibet,China

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.     

A New Species of Japalura(Squamata,Agamidae) from the Nu River Valley in Southern Hengduan Mountains,Yunnan, China

A population of Japalura from Yunnan Province, China, previously assigned to Japalura splendida, is described as a new species. The new species has been recorded between 1 138–2 500 m in the Nu River drainage between the towns of Liuku and Binzhongluo, and on the lower western slopes of the Nushan and eastern slopes of the Goaligongshan. The new species can be distinguished from other species of Japalura, except J. dymondi, by the following combination of characters: exposed tympani, prominent dorso-lateral stripes, and small gular scales. It is very similar with but differs from J. dymondi by having smooth or feebly keeled dorsal head scales, three relatively enlarged spines on either side of the post-occiput area, strongly keeled and mucronate scales on occiput area and within the lateral stripes, back of arm and leg green, higher number of dorsal-ridge scales(DS) and fourth toe subdigital scales(T4S). A principal component analysis of body measurements of adult male specimens of the new species and J. dymondi showed principal component 1 loading highest for upper arm length, fourth toe length and snout to eye length and principal component 2 loading highest for head width, head length and fourth toe length.
