Although Vietnam is in the focus of herpetological

research since decades (e.g., Nguyen, 2006; Nguyen

et al., 2009), there still remains a considerable number

of new records and even species descriptions regularly

being published from this country (e.g., Bain, Nguyen

and Doan, 2007; Ziegler and Nguyen, 2010) Recent

research in the Vietnamese-Chinese border region has

revealed a number of species descriptions (e.g., David et

al., 2012; Nguyen et al., 2010a, 2011b, 2012, 2013a, b)

which clearly underlines the poor research state of these

forested regions One of these poorly studied regions

in northeastern Vietnam near the Vietnamese-Chinese

border is Ha Giang Province Only a few studies have

been conducted in this province so far Most important

is the recent overview of Bain and Nguyen (2004),

describing two new species from that province including

a first provincial herpetofaunal list with 36 recorded

species of amphibians (33 identified and 3 unknown

species) and 16 recorded species of reptiles Further

new herpetofaunal records for Ha Giang Province were

published by Ziegler et al (2006b), Le and Ziegler

(2009), Nguyen, Ho and Nguyen (2009) and Nguyen et

al (2010b) Most recently, Ohler et al (2011) described

the megophryid anuran species Leptolalax nyx from Ha

Abstract Based on herpetological surveys conducted between December 2006 and May 2008 in the Tung Vai forest, Quan

Ba District, Ha Giang Province, northern Vietnam we recorded eight amphibian species (Hyla annectans, Babina chapaensis,

Odorrana cf jingdongensis, O junlianensis, Gracixalus cf jinxiuensis, Rhacophorus duboisi, R feae, and R robertingeri)

and twelve reptile species (Gekko cf palmatus, Sphenomorphus indicus, Cyclophiops major, C multicinctus, Euprepiophis

mandarinus, Lycodon meridionalis, Oligodon chinensis, Oreocryptophis porphyraceus, Orthriophis taeniurus, Pseudoxenodon macrops, Rhabdophis subminiatus, and Sinomicrurus macclellandii) for the first time for that province Based on our recent

findings together with literature surveys we provide an updated herpetofaunal list for Ha Giang Province, in total comprising

102 species (50 species of amphibians, and 52 species of reptiles)

Giang Province, and Nishikawa, Matsui and Nguyen

(2013) described a new salamander species, Tylototriton

ziegleri, from the northern provinces of Cao Bang and

Ha Giang pointing again towards the necessity of

ongoing research in these regions As a result of recent

field work in the Tung Vai forest in Ha Giang between

2006 and 2008 we herein provide new records of

amphibians and reptiles including an updated checklist

of the herpetofauna known from Ha Giang

Material and methods

Field surveys were conducted by Quyet Khac Le and

Thanh Ngoc Vu in the Tung Vai forest, Quan Ba District,

Ha Giang Province (Fig 1), northern Vietnam between

December 2006 and May 2008 The typical habitat

consisted of evergreen broad-leaved forest on limestone

affected by cultivation of cardamom (Amomum tsaoko)

Surveys were taken place along forest paths and

streams Specimens were photographed in the field and

subsequently released, or collected and photographed prior to preservation Specimens were fixed in 4% formalin or in 40-60% ethanol (amphibians) and 90% ethanol (reptiles) and subsequently transferred in 70 % ethanol for permanent storage Specimens referred to in this paper were deposited in the following collections: Institute of Ecology and Biological Resources (IEBR), Hanoi, Vietnam; Zoological Museum, Vietnam National University Hanoi (VNUH), Vietnam; Vietnam National Museum of Nature (VNMN), Hanoi, Vietnam; and Zoologisches Forschungsmuseum Alexander Koenig, Bonn (ZFMK), Germany

A total of 25 specimens of amphibians were collected

(Leptobrachium chapaense IEBR A.2013.94, ZFMK 95471; Xenophrys major ZFMK 95472; Hyla annectans IEBR A.2013.93, ZFMK 95473; Limnonectes cf bannaensis IEBR A.2013.95, A.2013.96, VNUH 19.11.04-1, ZFMK 95474; Quasipaa spinosa IEBR A.2013.97, VNUH 19.11.04-2, ZFMK 95475; Babina chapaensis IEBR A.2013.98, ZFMK 95476; Odorrana

Taxonomic identifications were based on Boulenger

(1893), Smith (1943), Bourret (1936, 1942, 2009),

Liu (1950), Taylor (1962), Schulz (1996), Ohler et al

Stuart (2006), Ziegler et al (2006a, 2007), Bourret

(2009), Chuaynkern et al (2010), Nguyen et al (2011a),

and Orlov et al (2012) Nomenclature for amphibians

followed Bain et al (2009), McLeod (2010), Yu, Zhang

and Yang (2010), Ohler et al (2011), Frost (2013), and

Nishikawa et al (2013); for reptiles Nguyen et al (2009),

Rösler et al (2011), and Luu et al (2013) Systematics

and common names followed Nguyen et al (2009) and

Tran et al (2010) unless otherwise stated

For amphibians, all measurements for morphological analyses were taken with a digital caliper to the nearest 0.1 mm Measurements of anurans were performed as follows: snout-vent length (SVL), from tip of snout to urostyle; head length (HL); head width (HW); snout length (SNL); horizontal eye diameter (ED); horizontal tympanum diameter (TD); interorbital distance (IO); width of upper eyelid (UEW); thigh length (THL); tibia length (TBL); webbing formula followed Myers and Duellman (1982) For reptiles, all measurements except for body and tail lengths were taken with a caliper to the nearest 0.1 mm Body and tail lengths were measured with a caliper to the nearest 1.0 mm Abbreviations are

as follows: snout-vent length (SVL), from tip of snout

to vent; tail length (TaL), from vent to tip of tail; dorsal scale formula (DSF): dorsal scale rows one head length behind the head : at midbody : one head length anterior

to the vent The number of ventral scales was counted according to Dowling (1951) Bilateral scales counts are given as right/left

Scale counts and measurements are lacking for those specimens which were photographed and directly released into the field afterwards Sex was determined

by examination of secondary sexual characters and sex

of collected specimens lacking distinct secondary sexual characters was determined by gonad inspection

formula I2–2½II1½–2½III2–3IV3–2V; inner metatarsal tubercle

distinct, small; dermal ridges along outer sides of tibia

and tarsal fold absent; dorsal surface of head, body and

thigh with small granules; dorsolateral fold absent;

throat and chest smooth, belly and ventral surface of

thigh granular; dermal appendage at vent absent

Coloration in preserved state: Snout and dorsum grey

with dark brown pattern forming an inverse Y marking;

a triangular pattern between eyes bifurcating into two

bands continuing posteriorly; lateral side of head and

flank grey without spots; tympanum brown; forelimb,

dorsal surface of thigh, tibia and foot grey with some

darker bars; throat, chest and belly immaculate cream

in life see Fig 3 (identification followed Nguyen et al.,

2008)

Remarks: The previous record of G jinxiuensis from

Quang Binh Province was reassigned to G quyeti

(Nguyen et al., 2008) Phylogenetic analysis by Rowley

et al., (2011) showed that G jinxiuensis is a species

complex

Rhacophorus duboisi Ohler, Marquis, Swan and

Grosjean, 2000

Dubois’ Whipping Frog / Ech cay duy-boa (Fig 3)

Specimens examined (n = 2): adult males (IEBR

A.2013.100, ZFMK 95481)

Distribution: Vietnam: Lao Cai Province Elsewhere:

expected in Yunnan, China (Nguyen et al., 2009)

Morphological features of examined specimens:

SVL 60.3–61.5 mm; head slightly longer than wide; snout pointed in dorsal view, its length larger than eye diameter; nostril round, closer to eye than to tip of snout; interorbital distance broader than upper eyelid width; tympanum distinct, round, its diameter about 0.6–0.7 times of eye diameter, and 1.9–2.4 times of space between tympanum and eye; supratympanic fold distinct; vomerine teeth in two oblique rows, connected

to choanae; tips of fingers and toes enlarged into discs with distinct circum-marginal grooves; two palmar tubercles flat and oval; finger webbing formula: I2¼–2

½II1½–3III2–2IV; toe webbing formula: I0–1II0–1III1–2IV2–1IV; outer side of toe V with dermal fringe; inner metatarsal tubercle slightly prominent, its length 0.3–0.4 times of the first toe length; outer metatarsal tubercle absent; dorsal surface of head, body, and limbs granular; flank slightly granular; throat, chest, belly, and ventral aspect

of thigh with small round flat granules

Coloration in life: Dorsal head, body and limbs green with dark large copper brown spots, edged in black and some small white spots; flank and posterior surface of thigh white with dark brown marbling; belly grey-white with numerous small, medium grey spots (identification followed Ohler et al., 2000)

Remarks: Both specimens agreed with the original

description of Ohler et al (2000) except for the following features: finger I as long as II (versus finger I<II); fringe along fifth toe extending to first subarticular tubercle and ending as a fold at base of tarsus (versus fringe along fifth toe terminating at first subarticular tubercle), a similar but narrower dermal fringe present along outside of first finger, from base of disc to inner metatarsal tubercle not mentioned by Ohler et al (2000);

and dorsal surfaces of head and body granular without

spinules (versus with horny spinules) R duboisi is very

similar to R puerensis, which was formerly reported

as R dugritei from Ha Giang Province by Bain and

Nguyen (2004) Li et al (2012) considered R puerensis

to be a valid species and referred the specimens of

the R dugritei complex from northern Vietnam to R

puerensis The specimens differ from R puerensis by

the larger size (SVL of males 60.3–61.5 mm vs 32–47

mm), and the more developed webbing on the first toe

of the specimens reaching to base of disc (versus the

webbing ending between the subarticular tubercle and

intercalary cartilage of the first toe of R puerensis, see

Liu, 1950, Bain and Nguyen, 2004)

Rhacophorus feae Boulenger, 1893

Brown-folded Treefrog / Ech cay phe (Fig 3)

Specimen examined (n = 1): photographic record

only

Distribution: Vietnam: Lai Chau, Lao Cai, Kon Tum,

Dak Lak, and Dong Nai provinces (Nguyen et al.,

2009)

Morphological features of photographed specimen:

Photographs of the individual resembled Rhacophorus

feae in the following attributes: Fingers and toes with

large discs and well webbed

Coloration in life: Dorsal surface uniformly green; a

golden stripe running from tip of snout, along to canthus

rostralis, border of upper eyelid, and supratympanic

fold to shoulder; webbing whitish (identification after

Boulenger, 1893 and Orlov et al., 2012)

Rhacophorus robertingeri Orlov, Poyarkov,

Vassilieva, Ananjeva, Nguyen, Nguyen and Geissler,

2012

Robert Tree frog / Ech cay ro-bot-in-go (Fig 3)

Specimen examined (n = 1): adult female (ZFMK

95480)

Distribution: Vietnam: in Thua Thien-Hue, Da Nang,

Quang Nam, Kon Tum, and Gia Lai provinces (Orlov

et al., 2012)

Morphological features of examined specimen: SVL

40.3 mm; head as long as wide; snout pointed; eye

large, its diameter about 0.76 times of snout length;

interorbital space 1.5 times of upper eyelid width;

tympanum visible, with a diameter smaller than half

of eye diameter; supratympanic fold distinct; tips of fingers and toes enlarged to discs; fingers and toes well webbed, finger webbing formula: I2–2½II1½–2½III2– 1½IV and toe webbing formula: I1½–2II1–2½III1–1IV1–1V; tibiotarsal articulation with a long pointed projection; dermal appendage at vent present; skin smooth dorsally and granular ventrally

Coloration in life: Dorsal head, body, and limbs yellow brown; a darker cross-bar present between eyes; posterior part of dorsum with some darker patches or bars; side of head yellow brown; eye with golden iris and horizontal black pupil; transverse bars on limbs present; webbings whitish (identification followed Orlov et al., 2012)

Remarks: Nostrils located midway between tip of

snout and eye (versus nostrils closer to tip of snout than to eye, see Orlov et al., 2012) Orlov et al (2012) also reidentified the Vietnamese specimens that

were formerly regarded as Rhacophorus calcaneus Smith, 1924, as a distinct species, R robertingeri and simultaneously synonymized Rhacophorus chuyangsinensis Orlov, Nguyen, and Ho, 2008 with

R calcaneus The IUCN Red List status of this species should be “Near Threatened” as that of the former R calcaneus

Squamata: Sauria Gekkonidae

Gekko cf palmatus Boulenger, 1907

Palm Gecko / Tac ke chan vit (Fig 4)

Specimen examined (n = 1): photographic record

only

Distribution: Vietnam: Yen Bai, Lang Son, Vinh Phuc,

Quang Ninh, and Quang Binh provinces Elsewhere: China, Myanmar, Laos, Thailand, and Cambodia (Nguyen et al., 2009, Uetz, 2013)

Morphological features of photographed specimen:

The photograph of this gecko largely resembles Gekko palmatus in the following characters: tubercles present

on dorsum; one pair of dark, roundish or somewhat enlarged spots in the occipital region; smaller, but more distinct dark spots in the nuchal region and light broken middorsal stripe evident on body (identification based

on Ziegler et al., 2006a and Nguyen et al., 2013b)
