A new species of small tree frog from a primary montane tropical forest of central Vietnam, Tay Nguyen Plateau, is described based on morphological, molecular, and acoustic evidence. The Golden Bug-Eyed Frog, Theloderma auratum sp. nov., is distinguishable from its congeners and other small rhacophorid species based on a combination of the following morphological attributes：（1） bony ridges on head absent; （2） smooth skin completely lacking calcified warts or asperities; （3） pointed elongated tapering snout; （4） vocal opening in males absent; （5） vomerine teeth absent; （6） males of small body size （SVL 21.8-26.4 mm）; （7） head longer than wide; ED/SVL ratio 13%-15%; ESL/SVL ratio 16%-20%; （8） small tympanum （TD/EL ratio 50%-60%） with few tiny tubercles; （9） supratympanic fold absent; （10） ventral surfaces completely smooth; （11 ） webbing between fingers absent; （12） outer and inner metacarpal tubercles present, supernumerary metacarpal tubercle single, medial, oval in shape; （13） toes half-webbed： I 2-21/4 II 11/^-23/~ III 2-31/4 IV 3-11/2 V; （14） inner metatarsal tubercle present, oval; outer metatarsal tubercle absent; （15） iris bicolored; （16） dorsal surfaces golden-yellow with sparse golden-orange speckling or reticulations and few small dark-brown spots; （17） lateral sides of head and body with wide dark reddish-brown to black lateral stripes, clearlyseparated from lighter dorsal coloration by straight contrasting edge; （18） ventral surfaces of body, throat, and chest greyish-blue with indistinct brown confluent blotches; （19） upper eyelids with few （3-5） very small flat reddish superciliary tubercles; （20） limbs dorsally reddish-brown, ventrally brown with small bluish-white speckles. The new species is also distinct from all congeners in 12S rRNA to 16S rRNA mitochondrial DNA fragment sequences （uncorrected genetic distance P〉8.9%）. Advertisement call and tadpole morphology of the new species are described. Our molecular data showed Theloderma auratum sp. nov.

作者： Nikolay A. Poyarkov Jr. Peter Geissler Vladislav A. Gorin Evgeniy A. Dunayev Timo Hartmann Chatmongkon Suwannapoom Department of Vertebrate Zoology Biological Faculty Lomonosov Moscow State University Moscow 119991 Russia joint russian-vietnamese tropical research and technological center Nghia Do Cau Giay Hanoi Vietnam Museum Natur und Mensch Freiburg 79098 Germany Zoological Museum Moscow State University Moscow 125009 Russia Zoological research Museum Alexander Koenig Bonn 53113 Germany School of Agriculture and Natural Resources University of Phayao Phayao 56000 Thailand

We provide an integrative taxonomic analysis of the Lipinia vittigera species complex from mainland Southeast Asia. Based on examination of external morphology, color pattern, and 681 base pairs of the cytochrome oxidase subunit I (COI) mitochondrial gene, we demonstrate the presence of four morphologically distinct lineages of Lipinia in Vietnam, Cambodia, Thailand, and Malaysia, showing a sequence divergence ranging 15.5%–20.4%. All discovered lineages are discretely diagnosable from one another by a combination of scalation traits and color patterns. A review of the published distribution data and a re-examination of available type material revealed the following results:(1) distribution of L. vittigera (Boulenger, 1894) sensu stricto is restricted to Sundaland and the Thai-Malay Peninsula south of the Isthmus of Kra;(2) L. microcercus (Boettger, 1901) stat. nov. is elevated to full species rank;the species has a wide distribution from central and southern Vietnam across Cambodia to eastern Thailand;we regard Lygosoma vittigerum kronfanum Smith, 1922 and Leiolopisma pranensis Cochran, 1930 as its junior synonyms;(3) Lipinia trivittata sp. nov. occurs in hilly areas of southern Vietnam, Cambodia, and eastern Thailand;and (4) Lipinia vassilievi sp. nov. is currently known only from a narrow area along the vietnamese-Cambodian border in the foothills of the central Annamite Mountain Range. We further provide an identification key for Lipinia occurring in mainland Southeast Asia.

The majority of our knowledge of avian energetics is based on studies of birds from temperate and high latitudes. Using the largest existing sample of wild-caught Old World tropical species, we showed that birds from Southern Vietnam had lower basal metabolic rate （BMR） than temperate species. The strongest dissimilarity between tropical and temperate species was the low scaling exponent in the allometric relation between BMR and body mass in tropical birds （the regression slope was 0.573）. The passerine migrants to temperate and high latitudes had higher BMR than tropical sedentary passerines. Body mass alone accounted for 93% of the variation in BMR （body mass ranged from 5 to 252 g）. Contrary to some other studies, we did not find evidence besides the above mentioned that phylogeny, taxonomy, behavior, or ecology have a significant influence on BMR variation among tropical birds.

Chamkarmorn Phnom Penh Cambodia Department of Vertebrate Zoology Biological Faculty Lomonosov Moscow State University Moscow 119234 Russia joint russian-vietnamese tropical research and technological Centre Nghia Do Cau Giay Hanoi Vietnam

Based on morphological and genetic evidence we evaluated the taxonomic status of a newly discovered forest-dwelling population of skink （genus Scincella） from the Keo Selma Wildlife Sanctuary, Mondulkiri Province, Cambodia. From phylogenetic analysis of a 668-bp fragment of the mtDNA COl and diagnostic morphological characters we allocate the newly discovered population to the Scincella reevesii-S. rufocaudata species complex and describe it as Scincella nigrofasciata sp. nov. The new skink species can be distinguished from all other Southeast Asian congeners by the following combination of morphological characters： snout-vent length （SVL） 40.0-52.6 mm; relative tail length （TaL/SVL ratio） 1.25-1.94; prefrontals in broad contact; infralabials 6; primary temporals 2; relative forelimb length （FIL/SVL ratio） 0.20-0.22; relative hindlimb length （HIL/SVL ratio） 0.30-0.33; relative forearm length （FoL/SVL ratio） 0.14-0.16; adpressed forelimbs and hind limbs either overlapping （0.4-2.2 mm） or separated （1.9-2.3 mm）; midbody scale rows 32-33, paravertebral scales 69-74, vertebral scales 65-69; dorsal scales between dorsolateral stripes 8; comparatively slender fingers and toes, subdigital lamellae under fourth toe 15-17; dark discontinuous regular dorsal stripes 5-7; distinct black dorsolateral stripes, narrowing to lateral sides and extending to 52%-86% of total tail length. We provide additional information on the holotype of Scincella rufocaudata （Darevsky ＆ Nguyen, 1983）, and provide evidence for the species status of Scincella rupicola. Our discovery brings the number of Scincellaspecies in Cambodia to five and emphasizes the incompleteness of knowledge on the herpetofaunal diversity of this country.

We describe a new karst-dwelling Cyrtodactylus from Ban Thathom, Xiangkhoang Province, northeastern Laos. The new species can be distinguished from other congeners by having four dark dorsal bands between limb insertions, a discontinuous nucha~ loop, 10 precloacal pores in males or 10-12 precloacal pits （females） separated by a diastema from a series of enlarged femoral scales bearing 18 or 19 pores （male） or 8-10 pits （females） along each femur, 14-18 dorsal tubercle rows at midbody, no precloacal groove, 30-36 midbody scale rows across belly between ventrolateral skin folds, transversely enlarged subcaudal plates, and a maximal known snout-vent length of 75.5 mm. Our description brings to 22 the number of Cyrtodactylus species recorded from Laos.
