“…Their results also rejected the hypothesis that Leptolalax consists of two subgenera as proposed by Delorme et al (2006) and Dubois et al (2010). At present, the genus Leptobrachella contains sixty-six species, widely distributed from southern China west to northeastern India and Myanmar, through mainland Indochina to peninsular Malaysia and the island of Borneo (Frost 2017; Nguyen et al 2018; Rowley et al 2016, 2017; Yang et al 2016; Yuan et al 2017). They are commonly known as Asian leaf litter frogs.…”

Based on morphological and phylogenetic analyses (16S rRNA mtDNA), two new species of the genus Leptobrachella are described from southern China, namely L.yunkaiensis Wang, Li, Lyu & Wang, sp. n. from Dawuling Forest Station of Guangdong Province and L.wuhuangmontis Wang, Yang & Wang, sp. n. from Mt. Wuhuang of Guangxi Province. To date, the genus Leptobrachella contains 68 species, among which 13 species are known from China. The descriptions of the two new species further emphasize that the species diversity of the genus Leptobrachella from China is still highly underestimated and requires further investigations.

“…With the evidence of both morphological and phylogenetic analyses, 15 cryptic species of the genus Leptobrachella have been discovered and described since 2010 (Frost 2017; Rowley et al 2016, 2017; Yang et al 2016; Yuan et al 2017). With the description of L.yunkaiensis sp.…”

“…The sonograms and waveforms were generated by Raven Pro 1.5 software (The Cornell Lab of Ornithology, available from http://www.birds.cornell.edu/raven ) with Fast Fourier samples 512 points and overlap 50%, from which all parameters and characters were measured as following Rowley et al (2012) . Comparative advertisement call characters for congeners in the subgenus Lalos species were taken from references, with advertisement calls known for 18 out of the 38 known species of in the subgenus Lalos ( Matsui, 2006 ; Rowley & Cao, 2009 ; Rowley et al, 2010a ; Rowley et al, 2010b ; Rowley et al, 2010c ; Rowley et al, 2011 ; Rowley et al, 2012 ; Rowley, Dau & Nguyen, 2013 ; Rowley et al, 2015a ; Rowley et al, 2016 ; Rowley et al, 2017 ; Poyarkov et al, 2015 ; Rowley, Dau & Cao, 2017 ).…”

The Asian leaf litter toads of the genus Leptolalax represent a highly diverse species group and currently contain 53 recognized species. During herpetological surveys in Yingjiang County, western Yunnan of China, we collected series of Leptolalax specimens from an isolated small fragment of montane evergreen forest. Subsequent study based on acoustic, morphological and molecular data reveals that there were three different species among the specimens sampled: while one of them belongs to Leptolalax ventripunctataus, the other two species represent unknown taxa and are described herein: Leptolalax purpurus sp. nov. and Leptolalax yingjiangensis sp. nov. The two new species can be distinguished from other congeners by the molecular divergences, acoustic data, and by a combination of morphological characters including: body size, dorsal and ventral patterns, dorsal skin texture, sizes of pectoral and femoral glands, degree of webbing and fringing on the toes and fingers, dorsum coloration and iris coloration in life. Our results further reveal that species diversity of the genus Leptolalax still remains highly underestimated and warrants further attention.

“…Total DNA was extracted from muscle tissue using standard phenol-chloroform extraction ( Hillis et al, 1996 ), followed by isopropanol precipitation. We amplified a 454–474-bp length fragment of the 16S rRNA mitochondrial gene, which has been successfully applied for DNA-identification of cryptic diversity within the genus Leptolalax ( Poyarkov et al, 2015a ; Rowley et al, 2015a , 2016 , 2017a , 2017b ). The 16S rRNA-gene fragment was amplified using ScreenMix-HS (Evrogen, Russia) following the manufacturer’s instructions.…”

“…Knowledge about Leptolalax species diversity has strikingly increased in recent decades, from only four in 1983 ( Dubois, 1983 ) to 53 recognized species at present, 31 of which (~60% of total species) have been described in the last 10 years ( Frost, 2017 ). In Vietnam, the number of Leptolalax species has increased remarkably from six ( Nguyen et al, 2009 ) to 23 species ( Rowley et al, 2016 , 2017a , 2017b ) within the last decade. However, considering the high morphological similarity of many species within the genus ( Rowley et al, 2016 ) and the poor level of biological exploration of many parts of Indochina, additional taxa likely remain undescribed.…”

We describe a new species of megophryid frog from Phu Yen Province in southern Vietnam. Leptolalax macrops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes: (1) body size medium (SVL 28.0–29.3 mm in three adult males, 30.3 mm in single adult female); (2) supra-axillary glands present, creamy white; ventrolateral glands indistinct; (3) tympanum externally distinct; (4) dorsal skin roughly granular with larger tubercles, dermal ridges on dorsum absent; (5) rudimentary webbing present between fingers I–II and II–III; rudimentary webbing between all toes; fingers and toes without dermal fringes; (6) in life ventral surface greyish-violet with white speckling; (7) supratympanic fold distinct, dark brown in life; (8) iris bicolored, typically golden in upper half, fading to golden green in lower half; (9) tibia short (TbL/SVL 0.44–0.45 in males); and (10) eyes large and protuberant (ED/SVL 0.15–0.16 in males). From all congeners for which comparable sequences are available, the new species differs markedly in the 16S rRNA mitochondrial gene sequence (P-distance>5.7%). The new species is currently known only from montane evergreen tropical forests of Song Hinh District, Phu Yen Province, and M’Drak District of Dak Lak Province at elevations of 470–630 m a.s.l.. We suggest the new species should be considered as Data Deficient following the IUCN’s Red List categories. We also report a previously unknown Leptolalax mtDNA lineage from an evergreen tropical forest in the Hoa Thinh District of Phu Yen Province, which may also represent an undescribed species.
