Specimens examined. Two adult female specimens SYS a001046 and SYS a001047, an adult male specimen SYS a001048 from Bainan village (23° 3'15.56" N, 105°48'57.85" E; 330 m a.s.l.), Napo County, Guangxi Zhuang Autonomous Region, China, collected by JHY and RLL on 6th august 2010.
Description of specimens from China. The head length greater than width, HDL: HDW 1.08–1.14 in females, 1.21 in male; head width 0.30–0.35 times of SVL in females, 0.33 times of SVL in male; head length 0.34–0.37 times of SVL in females, 0.40 times of SVL in male; snout short, rounded in dorsal view, bluntly rounded in profile, projecting beyond margin of lower jaw; eye large, eye diameter 0.72–0.90 times of SNT, upper eyelid wider than interorbital distance; top of head flat; canthus rostralis rounded; lip flared; loreal region concave; internasal distance larger than interorbital distance; tympanum circular, large, distinctly visible, tympanum diameter 0.47–0.52 times of eye diameter in females, 0.62 times in male; tympanum-eye distance small (TED 2.9– 3.4 mm in female, 0.8 mm in male); Choanae ovoid; vomerine dentigerous processes prominent, slightly oblique, posteromedial to choanae; tongue cordiform, distinctly notched posteriorly.
Forelimbs moderately robust; hand length 0.28 times of SVL in females, 0.31 times in male; relative finger lengths II <I <IV <III; fingers free of webbing, tips of fingers dilated, becoming pointed, cordiform disks; width of disk significantly greater than width of distal phalanx of finger III, FPW:DPW = 1.61–1.92 in females, 1.87 in male; terminal phalanges T-shaped; lateroventral circummarginal grooves not meeting at the tip of dicks; subarticular tubercles conical; supernumerary tubercle below the base of each finger, distinct, significantly smaller than subarticular tubercles; metacarpal tubercle three, elongated and distinct. Hindlimbs robust, relatively long; tibio-tarsal articulation beyond the tip of snout when hindlimb adpressed along the side of the body; heels overlapped when the flexed hindlimbs held at right angles to the body axis; tibia length 0.56–0.59 times of SVL in females, 0.62 times in male; feet length 0.75–0.78 times of SVL in females, 0.85 times in male; relative toe lengths I <II <III <V <IV; tips of toes dilated, becoming rounded triangular disks; circummarginal grooves present; feet fully webbed to disks, but as a fringe from distal subarticular tubercle of toe IV; slight lateral fringes on toes I and V to terminal phalanges; subarticular tubercles prominent, conical; inner metatarsal tubercle elongated, ovoid; outer metatarsal tubercle absent; inner tarsal fold absent.
Skin on dorsum shagreened with dense granules; a number of tubercles and pustules scattered on flanks of trunk; dorsolateral folds absent; supratympanic folds slightly prominent, from posterior corner of eye, curving posteroventrally, extending to a level above insertion of arm; small tubercles anterior and posterior to tympanum; venter smooth, no pectoral spinules; distinct granules present on posterior thighs and around cloaca; cloacal opening unmodified, directed posteriorly, at upper level of thighs.
Dorsum of head and body brown with reticulated green markings anterior to sacral vertebra; upper part of flank brown, lower part of flank light yellow with several large black spots; upper and lower lips creamy yellow with vertical black bars; dorsal limbs and digits brown with black transverse bands; webbing on feet marbled white and dark brown; venter creamy white; iris golden, margin of pupil outlined in a striking reddish yellow border.
The adult female specimens SYS a001046 and 1047 possessed black mature oocytes (1.8 mm in diameter) in life; adult male specimen SYS a001048 with developed testes (size of 1.6× 2.3 mm), nuptial pad on finger I, paired gular pouches at corners of throat.
Variation. Measurement and body proportions of all specimens from Napo County, Guangxi are listed in Table 3. The Chinese specimens basically match with the original description of Bain et al. (2003), but also show morphological difference, especially in color pattern. Specifically, the dorsum of head and body decorated with reticulated green markings in Chinese specimens (lacking same green markings in original description of Bain et al. (2003)). In addition, head length 1.21 times of head width, 0.40 times of SVL in male SYS a001048. In contrast, Bain et al. (2003) reported that the head of male paratype FMNH 255611 extraordinary long, head length 1.55 times of head width, 0.51 times of SVL (SVL 54.9 mm, HDL 28.0 mm, HDW 18.1 mm).Therefore, the measurement data from the original description might be inaccurate.
Revised diagnosis. (1) SVL 35.6–54.9 mm in adult males, 78–105 mm in adult females; (2) vomerine teeth present in rows oblique to choanae; (3) vertical black stripes on lip, especially distinct under eye; (4) tympanum circular, distinct, TYD:ED 0.47–0.52 in females, 0.62–0.66 in the male; (5) supratympanic fold weak; (6) dorsal skin shagreened, becoming tubercles and pustules laterally; (7) dorsolateral fold absent; (8) venter smooth, no pectoral spinules; (9) dorsum brown with black blotches, sometimes dorsum of head and body decorated with reticulated green markings; (10) disks on fingers and toes enlarged; (11) feet fully webbed to disks, but as a fringe from distal subarticular tubercle of IV, slight lateral fringes on toes I and V to terminal phalanges; (12) subarticular tubercles distinct, conical; (13) male with nuptial pad on finger I; (14) paired gular pouches; (15) oocytes black.
Distribution. The Chinese specimens collected from Bainan River, located in the China-Vietnam border at night, represent the first record of O. bacboensis for China. Furthermore, our molecular phylogenetic analyses revealed that voucher HNNU HK 001, which was misidentified as O. tiannanensis in Chen et al. 2013, from Hekou County, Yunnan, China, also is classified to O. bacboensis. The Hekou County bordering on Vietnam, at a distance of 200 km away from Bainan Village, Napo County, Guangxi (Fig. 1). Therefore, area of occurrence of O. bacboensis may be significantly expanded.
