Gastrointestinal helminths of nine species of Cnemaspis (Squamata: Gekkonidae) from Peninsular Malaysia,one species from Cambodia and Thailand and two species from Vietnam

A total of 12 species of Cnemaspis (N = 104) from Southeast Asia were examined for gastrointestinal helminths. Samples consisted of nine species (n = 86) from Peninsular Malaysia: Cnemaspis affinis (n = 4); Cnemaspis baueri (n = 17); Cnemaspis biocellata (n = 12); Cnemaspis grismeri (n = 8); Cnemaspis kumpoli (n = 11); Cnemaspis limi (n = 9): Cnemaspis monachorum (n = 7); Cnemaspis pemanggilensis (n = 10); Cnemaspis peninsularis (n = 8); one species (n = 5) from Cambodia and Thailand, Cnemaspis chanthaburiensis (n = 5); and two species (n = 13) from Vietnam: Cnemaspis nuicamensis (n = 6) and Cnemaspis tucdupensis (n = 7). The aggregate helminth community consisted of one species of Cestoda, Cylindrotaenia malayi and nine species of Nematoda: Bakeria schadi, Meteterakis singaporensis, Parapharyngodon maplestoni, Maxvachonia sp., Physalopteroides sp., Physalopteridae gen. sp., Riticulariidae gen. sp., Seuratoidea gen. sp., Ascaridoidea gen. sp. Meteterakis singaporensis had the largest number of individuals (457) and greatest prevalence (24%). Twenty-eight new host records are reported.     

原尾蜥虎雌性生殖周期的研究

从原尾蜥虎的卵巢重量，输卵管重量，卵巢内最大卵泡的长径，输卵管上皮厚度及输卵管中含卵数的季节性变化，观察了雌性生殖周期，结果表明：卵巢的周期性变化开始于１１月份，冬眠期间卵巢增重缓慢，出蛰后增重加快，到次年６，７月份其重要为最小值，一个周期至此结束。原尾蜥虎一年繁殖一次，每次产卵２枚（偶尔１枚），６，７月份为卵成熟及排卵的高峰期，而孕卵、产卵的高峰期是６￣８月份。     

Phylogenetic taxonomy of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) with descriptions of three new species from Myanmar

ABSTRACT

A phylogenetic taxonomy of the gekkonid genus Hemiphyllodactylus based on molecular, morphological, and ecological data recovered 28 species, including three new species from the upland regions of the Shan Plateau in eastern Myanmar. Hemiphyllodactylus linnwayensis sp. nov. is a forest-adapted species that may also be a human commensal and H. montawaensis sp. nov. and H. tonywhitteni sp. nov. are karst forest-adapted species. The discovery of three new species from montane regions in eastern Myanmar extends the distribution of a larger monophyletic group of Hemiphyllodactylus westward to the eastern edge of the Ayeyrawady Basin through a series of semi-contiguous, parallel mountain ranges originating in western China and northern Thailand. The discovery of the karst forest-adapted H. montawaensis sp. nov. and H. tonywhitteni sp. nov. further emphasizes the unrealized herpetological diversity endemic to karst ecosystems and the need for increased field work throughout such habitats in South-East Asia.

西域沙虎的核型分析

本文报导的西域沙虎（Ｔｅｒａｔｏｓｃｉｎｃｕｓｐｒｚｅｗａｌｓｋｉｉ）核型为２ｎ＝３６，由一对（１）亚端部着丝点染色体、１２对（２－１３）端部着丝点染色体及５对（１４－１８）不能明显确定着丝点位置的染色体组成。染色体均无明显的界线，不能象一般爬行类那样划分出大染色体和小染色体，这与壁虎科其它种类相一致，只是中间着丝点及亚中间着丝点染色体缺乏，故尔染色体臂数较少，另外染色体数目也较一般壁虎科种类少，表明沙虎与壁虎间既有联系、又具有一定的差异性。     

A systematic review of the genus Uroplatus (Reptilia: Gekkonidae), with comments on its biology

The gekkonid lizard genus Uroplatus is comprehensively reviewed for the first time. Six species are recognized—U. fimbriatus, U. sikorae, U. lineatus, U. ebenaui, U. alluaudi and U. guentheri—and their potential interrelationships are examined. Numerous bizzare morphological features, characteristic of the highly derived species U. fimbriatus, are found to be shared with other members of the genus, but are not universal for this taxon. Thus, while U. fimbriatus exhibits an overall morphology that has been employed in the past as justification for elevating the genus to monotypic familial status, this represents only an extreme of a continuum. U. guentheri and U. alluaudi are much less unusual in their morphological features. The potential biological roles of the more extreme features found within the genus are considered.     

疣尾蜥虎线粒体基因组全序列及其基因组成

测定了疣尾蜥虎(Hemidactylus frenatus) 的线粒体基因组全序列.序列全长为16 891 bp, 包括13 个蛋白质编码基因、2 个rRNA 基因和22 个tRNA 基因.除大部分基因由重链编码外,仅1个蛋白编码基因和8个tRNA基因由轻链编码.碱基组成的偏好与其他脊椎动物线粒体DNA接近.没有发现长的基因间隔区,说明该基因组的结构十分紧凑.基因组的组成与典型脊椎动物的相近,即没有发现重排、基因或控制区的重复等在其它有鳞类动物中出现过的异常特征.除单性生殖的壁虎外,现有的壁虎类线粒体基因组在基因含量和顺序上是一致的.作为蜥虎属线粒体基因组全序列的惟一代表,该序列有望在有鳞类系统发生的推断上发挥一定的作用.
