C751178C0DD74AB6D6BD745D51C5EEA0.taxon	distribution	Distribution and remarks. Stuart et al. (2006) described a large-sized Ophryophryne from O'Rang (also spelled as " O'Reang ") District in eastern Cambodia, close to the Vietnamese border, as O. synoria (Loc. 1, Fig. 1). Subsequently, during field surveys in 2009 - 2011, the species was reported in southern Vietnam from Bu Gia Map N. P., Binh Phuoc Prov. (Loc. 2, Fig. 1) and Cat Tien N. P. in Dong Nai Prov. (Loc. 3, Fig. 1) based on morphological evidence (Vassilieva et al. 2016). Herein, we confirm the identity of these specimens based on morphological and molecular genetic evidence, and further expand its distribution in southern Vietnam to include medium and low elevation localities in the central and western parts of the Langbian Plateau (Dak Lak, Lam Dong, Dong Nai and Binh Phuoc provinces between 200 and 1500 m a. s. l.; its presence in Dak Nong Prov. is anticipated). We also identify two mtDNA lineages within O. synoria with a moderate level of sequence divergence (p = 2.6 %: Table 2, Fig. 2): Subclade B inhabits mountain areas in Lam Dong and Dak Lak provinces and was also recorded for the lowland habitat in Dong Nai Prov. (Locs. 3 - 4, 6 and 11, Fig. 1) whereas Subclade C is only found in Mondolkiri Prov. of Cambodia and adjacent Binh Phuoc Prov. of Vietnam (Fig. 1, Locs 1 - 2) and corresponds to O. synoria s. stricto.	en	Jr., Nikolay A.

4676B3E4DA1ECAE042E7B551BD5CDD6B.taxon	etymology	Etymology. The specific epithet is an adjective (in agreement with the genus name in feminine gender), derived from " elf ", the English spelling of " alfus " in Latin, referring to usually forest-dwelling supernatural mythological creatures in Germanic mythology and folklore; the name is given in reference both to the funny appearance and small size of the new species, as well as to the their endangered habitat, restricted to wet evergreen montane forests at high elevations of the Langbian Plateau; such forests are often called " elfin forests ".	en	Jr., Nikolay A.

4676B3E4DA1ECAE042E7B551BD5CDD6B.taxon	diagnosis	Diagnosis. The species is allocated to Ophryophryne based on its obvious similarities with its sister taxa, its molecular phylogenetic affinities, and the absence of maxillary teeth considered diagnostic for the genus (previous authors, e. g. Ohler 2003, Delorme et al. 2006 and Fei et al. 2009 also indicated a horizontal pupil and the absence of vomerine teeth as diagnostic for Ophryophryne, this is reconsidered by Mahony et al. 2017). Ophryophryne elfina sp. n. is distinguished from its congeners by a combination of the following morphological attributes: (1) small adult body size, male SVL 26.9 - 33.9 mm (N = 29), female SVL 35.1 - 36.5 mm (N = 6); (2) snout sharply protruding in profile; (3) tympanum diameter approximately half of eye diameter; tympanum to eye distance approximately 70 - 90 % of tympanum diameter; (4) finger length formula: F 1 <F 4 ≤ F 2 <F 3, or F 1 ≤ F 2 <F 4 <F 3; toe webbing rudimentary, toe length formula: T 1 <T 5 <T 2 <T 3 <T 4; (5) short dorsolateral glandular ridge present above shoulder; (6) palpebral projection present as a small single tubercle to moderately developed single projection; (7) dermal cloacal protuberance and dermal flaps above cloacal opening absent; (8) skin of dorsal and lateral surfaces of head, body and limbs shagreened with numerous small tubercles, large warts on the flanks; (9) skin on dorsal and lateral surfaces of body, head and limbs with numerous bright orange-red (in life) asperities; (10) males with a red-orange (in life) nuptial pad on F 1; (11) dorsal coloration light yellow-brown with dark hourglass-shaped marking on dorsum usually edged with white or beige (in life); (12) posterior suborbital light bar well-defined, usually clearly separated from dark-brown temporal triangular spot, uniformly covering temporal area and tympanum. The new species is also markedly distinct from all congeners for which comparable sequences are available (16 S rRNA mitochondrial gene; uncorrected genetic distance> 8.2 %). The advertisement call of the new species consists of whistling notes uttered in series: average 12.84 + / - 0.41 calls per series, with an average dominant frequency of 4645.94 + / - 4.39 Hz, repetition rate per recording / series 1.18 + / - 0.2 calls / s and 3.87 + / - 0.07 calls / s, respectively, with average call duration 73 + / - 0.23 ms and inter-call interval 207 + / - 2.06 ms, also distinguishes the new species from Ophryophryne species for which calls are known, including the two species found in sympatry.	en	Jr., Nikolay A.

4676B3E4DA1ECAE042E7B551BD5CDD6B.taxon	description	Tadpole description. Tadpoles were allocated to Ophryophryne elfina sp. n. based on the following evidence: (1) morphological features characteristic for megophryine larvae in general; Ophryophryne or Megophrys s. lato in particular (elliptical shaped body with long muscular tail, oral disk forms a dorsally oriented funnel); (2) collected in the stream where calling males of the new species were recorded; (3) species identification confirmed by mtDNA sequences of short 16 S rRNA gene fragment (up to 500 bp) (GenBank Acession numbers: KY 515232 - KY 515233, see Table 1). Standard tadpoles measurements (mean + / - SD, N = 5, Stage 25; ZMMU A- 5679, field number NAP- 01169, collected from Bidoup Mt., 1900 m a. s. l., Bidoup-Nui Ba N. P., Lam Dong Prov.) (all in mm, taken by NAP): TOL = 28.4 + / - 1.3 (27.4 - 30.2); BL = 8.6 + / - 0.1 (8.4 - 8.7); TAL = 19.8 + / - 1.2 (18.9 - 21.5); BW = 4.4 + / - 0.4 (3.8 - 4.6); BH = 3.6 + / - 0.2 (3.4 - 3.7); TH = 4.5 + / - 0.4 (4.0 - 4.8); SVL = 9.2 + / - 0.3 (9.0 - 9.5); SSp = 4.8 + / - 0.2 (4.5 - 4.9); UF = 1.4 + / - 0.1 (1.3 - 1.5); LF = 1.1 + / - 0.0 (1.1 - 1.1); IN = 2.6 + / - 0.1 (2.5 - 2.6); IP = 2.8 + / - 0.2 (2.7 - 3.2); RN = 1.7 + / - 0.1 (1.7 - 1.8); NP = 0.8 + / - 0.1 (0.7 - 0.8); ED = 0.8 + / - 0.0 (0.8 - 0.9). The following description is based on five tadpoles at stage 25 (ZMMU A- 5679, field number NAP- 01169). In lateral view (Fig. 11 A), body slightly compressed dorsoventrally (BH / BW 83.5 + / - 4.09 %), especially anteriorly, convex both dorsally and ventrally. Body elliptical in dorsal view (Fig. 11 B), with maximum width at middle of body (BW / BL 51.0 + / - 4.2 %); snout short, rounded, blunt. Eyes of moderate size (ED / BL 9.8 + / - 0.3 %), not bulging, separated by a distance which equals approximately 1.1 times internarial distance (IP / IN 110.2 + / - 6.8 %), directed and positioned dorsolaterally, not visible in ventral view; pupils oriented dorsolaterally.

Spiracle sinistral, conical, very short, opening at half of distance from snout tip to vent (SSp / SVL 52.2 + / - 3.4 %); spiracle attached to body wall for most of its length, extremity is free, positioned at the level of longitudinal axis, oriented dorsoposteriorly, opening varies from rounded to oval. Tail long, more than two times longer than body (TAL / BL 231.3 + / - 11.0 %), lanceolate; almost equal in height along its length (point of maximum height of tail located just anterior to midlength of tail); tail tip bluntly rounded, without terminal filament; tail musculature strong, gradually tapering, almost reaching tail tip. Tail fins shallow, moderately well developed, not extending onto body: dorsal fin originating almost at body-tail junction, much shorter than lower fin proximally and nearly equal in height to it on middle of tail; dorsal fin slightly higher than ventral fin on distal half of tail (LF / UF 77.1 + / - 4.9 %); free margin of dorsal fin horizontal and shallow on anterior half of tail; free margin of ventral fin parallel to tail musculature. Vent opening medial, tubular, directed posteriorly, not linked to ventral tail fin. Neither skin glands nor neuromasts visible in preservative, but neuromasts of the lateral line system are distinct in life (Fig. 12 A) forming two curved lines running from snout towards orbits and along orbital margins ventrally. Subterminal oral disk with lips expanded vertically forming a dorsally oriented funnel (Fig. 11 B); lateral corners of funnel distinct; upper lip notably smaller than lower; lips lack keratodonts, but bear short, low ridges, more densely arranged on upper than on lower labium, arranged in 18 - 24 (mean = 22) longitudinal rows and from 2 - 4 (mean = 3) transverse rows on upper labium to 4 - 6 (mean = 5) transverse rows on lower labium. Marginal papillae absent. Width of expanded funnel comprises over 75 % of body length (Fig. 12 A) and just 30 % when folded in preservation (Fig. 12 B). In life tadpoles have dorsal side of body and upper flanks uniform brownish red or brownish orange (Fig. 12 A, B). Lower flanks weakly mottled with dark brown, few round blackish spots on tail and dorsum; with orange neuromasts visible on dorsal surface (Fig. 12 A). Abdomen light brownish orange, intestine not visible through body wall. Caudal muscles pale; tail fins translucent with a few darker spots (more on upper than on lower fin); dorsally tail with indistinct middorsal orange line (Fig. 12 A). Eyes golden with black reticulations. Oral funnel pinkish orange with brownish red papillae (Fig. 12 B). In preservative tadpole coloration gets much duller, but the general coloration pattern is still visible after 7 years in ethanol.	en	Jr., Nikolay A.

4676B3E4DA1ECAE042E7B551BD5CDD6B.taxon	distribution	Distribution. Ophryophryne elfina sp. n. is found to be endemic to five provinces in (Lam Dong, Dak Lak, Khanh Hoa, Ninh Thuan and Phu Yen) in the northern and eastern part of the Langbian Plateau and its foothills in southern Vietnam (localities 6 - 12, Fig. 1). The new species is restricted to wet evergreen montane tropical and elfin forests, receiving high precipitation from the sea. Such wet forests are found only on high elevations in the central parts of the Langbian Plateau (e. g. 1900 - 2100 m a. s. l. on Bidoup Mt., Lam Dong Prov., Fig. 1, Loc. 6) or peripheral mountains remote from the sea (e. g. 1900 - 2300 m a. s. l. on Chu Pan Fan and Chu Yang Sin Mts., Dak Lak Prov., Fig. 1, Locs 10 and 11), but on the eastern foothills of the plateau which receive more precipitation, the new species is found at lower elevation (from 950 to 1510 m a. s. l. on Hon Ba Mt., Khanh Hoa Prov., Fig. 1, Loc. 8; 780 m a. s. l. on Nui Chua Mt., Ninh Thuan Prov., Fig. 1, Loc. 9; and 700 m in Phu Yen Prov., Fig. 1, Loc. 12).	en	Jr., Nikolay A.
