Full textAbstract:
A new species of the Asian leaf litter toad genus Leptobrachella is described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in the Leptobrachella clade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.7–31.2 mm in five adult males); dorsal skin shagreened, some of the granules forming longitudinal short skin ridges; tympanum distinctly discernible, slightly concave; supra-axillary, femoral, pectoral and ventrolateral glands distinctly visible; absence of webbing and lateral fringes on fingers; toes with narrow lateral fringes but without webbing; heels overlapping when thighs are positioned at right angles to the body; tibia-tarsal articulation reaching the middle of eye when leg stretched forward. The discovery highlighted the underestimated species diversity in the Leptobrachella toads in southwestern China.

This study describes a new species of the genus Leptobrachella, Leptobrachella suiyangensis sp. nov. from the Huoqiuba Nature Reserve, Suiyang County, Guizhou Province, China, based on morphological data and phylogenetic analyses (16S rRNA mtDNA). The new species can be distinguished from other congeners by the molecular divergence and by a combination of morphological characters, including body size, dorsal and ventral patterns, dorsal skin texture, size of the pectoral and femoral glands, degree of webbing and fringing on the toes and fingers, dorsum coloration, and iris coloration in life. Currently, the genus Leptobrachella contains 75 species, 21 of which are found in China, including seven species reported from Guizhou Province. The uncorrected sequence divergence percentage between Leptobrachella suiyangensis sp. nov. and all homologous DNA sequences available for the 16S rRNA gene was found to be >4.7%. The new record of the species and its relationships with others in the same genus imply that species distribution, habitat variation, environmental adaptation, and diversity of the genus Leptobrachella in southwest China need to be further investigated.

Two new species, Leptobrachella phiaoacensis sp. nov. and Leptobrachella phiadenensis sp. nov., are described from Phia Oac-Phia Den National Park, Cao Bang Province, Vietnam based on genetic divergence and morphological differences. Leptobrachella phiaoacensis sp. nov. is characterized by a combination of the following characters: size medium (27.8–33.3 mm in five adult males and 31.5–41.8 mm in five adult females); head longer than wide; tympanum distinct; dorsal skin shagreened with fine tubercles; toes webbing rudimentary, with narrow lateral fringes; supratympanic fold edged by a distinct black line; the presence of a dark brown triangle in interorbital region and a W-shaped marking in scapular region; belly from pinkish white to white with dark brown specking on belly periphery; iris bicolored copper in upper part, fading to silvery grey in lower part. Leptobrachella phiadenensis sp. nov. is distinguished from its congeners by a combination of the following morphological characters: size medium (27.6–28.6 mm in two adult females); head wider than long; tympanum distinct; skin on dorsal head and body rough with warts, tubercles and dermal ridges; toes webbing rudimentary, with narrow dermal fringes; supratympanic fold orange; dorsal surface of head and body with some large dark brown markings, a dark brown triangle in interorbital region, edged in white; flank light brown with some dark flecks; belly white with dark specking on outer margins; iris bicolored, copper in upper part, fading to silvery grey in lower part. In terms of genetic distance, the two new species differ from each other and other congeners for which comparable sequences are available by at least 3.7% (16S rRNA gene). Recognition of these new species brings the total number of known species in the genus Leptobrachella from Vietnam to 34.

A new poroid wood-inhabiting fungus in the family Irpicaceae, Irpex jinshaensis sp. nov., is described and illustrated from China based on morphological and molecular evidence. The species was collected in Yunnan Province, where it grew on the undersides of fallen angiosperm branches. I. jinshaensis is characterized by an annual growth habit, resupinate basidiocarp with white to cream pores when fresh becoming salmon to cinnamon upon drying, a monomitic hyphal system, generative hyphae thick-walled with simple septa, and occasionally covered with small crystal granules, the presence of encrusted cystidia and subglobose to globose basidiospores. The phylogenetic analysis based on ITS + nLSU rDNA sequences shows that the new species belongs to Irpex, clustering with I. hydnoides, I. hacksungii and I. lacteus with strong support. In addition, a new combination, I. subulatus, is proposed based on morphological and phylogenetic analyses. Morphological and molecular characters confirm the placement of both the new species and the combination in Irpex. A key to the species of Irpex known from China is provided.

This study describes a new member of the genus Leptobrachella, Leptobrachella shangsiensis sp. nov., based on morphological, acoustic and molecular analyses from southern Guangxi, China. L. shangsiensis sp. nov. differs from its congeners by a combination of the following characters: (1) SVL 24.9–29.4 mm in 11 males and 30.8–35.9 mm in 5 females, (2) black supratympanic fold with dark reddish rim, (3) ventrolateral glands distinct, forming a broken line, (4) ventral surface yellowish creamy-white with marble texture, (5) iris copper in the upper and silver in the lower fifth and (6) toe webbing basal and narrow lateral fringes. The male advertisement call of L. shangsiensis sp. nov. consists of one note per call, lacking an introductory note, with a mean dominant frequency of 5.5–6.5 kHz at the ambient temperature of 21.5ºC. Uncorrected sequence divergences between L. shangsiensis sp. nov. and all homologous DNA sequences available for the 16S rRNA gene were found to be > 5.9%. L. shangsiensis sp. nov. occurs in an evergreen forest in Shiwandashan National Nature Reserve located at an elevation of 450–550 m.

The genus Leptobrachella is one of the most speciose and taxonomically troubling groups of Asian anurans. Herein, we describe a new species of Leptobrachella from Doi Inthanon, Chiang Mai Province, Thailand based on the integration of morphological, acoustic and molecular data. The new species, Leptobrachella murphyi sp. nov., is morphologically distinguished from its congeners on the basis of body size, dorsal skin texture and coloration, ventral coloration and pattern, degree of webbing and fringing on the fingers and toes, iris coloration in life, pattern of markings on flanks and pattern of body macroglands. It also differs from its phylogenetically close congeners by an uncorrected p-distance of >9.6% for a fragment of 16S rRNA. The advertisement call of the new species consists of 4.5–4.7 kHz (at 15 °C) and without a distinct introductory note. Leptobrachella murphyi sp. nov. likely occurs across the Thanon Thong Chai Range and analyses provide evidence of unknown biodiversity and species composition on Doi (mountain) Inthanon. In addition, the congeneric species L. minima was also confirmed in Doi Inthanon. The coexistence pattern of Leptobrachella in Doi Inthanon deserves further study. As Thailand’s highest mountain and biodiversity reservoir, the need for further biological exploration is urgent given ongoing habitat loss and degradation.

A new species of the genus <i>Leptobrachella</i>, <i>L. guinanensis</i> sp. nov., is described in this study based on morphological, molecular, and bioacoustic data. The species was discovered in the Shiwandashan National Nature Reserve in Shangsi County, Guangxi, China. Phylogenetically, <i>L. guinanensis</i> sp. nov. is closely related to <i>L. ventripunctata</i>. However, there are distinct morphological differences between <i>L. guinanensis</i> sp. nov. and <i>L. ventripunctata</i>, as well as three other sympatric species (<i>L. shangsiensis</i>, <i>L. shiwandashanensis</i>, and <i>L. sungi</i>). These differences include body size (SVL 30.5–32.5 mm in males; 38.7–41.8 mm in females in the new species vs 25.5–28.0 mm in males, 31.5–35.0 mm in females in <i>L. ventripunctata</i>), the absence of brown spots on the ventral surface (vs chest and belly creamy white with many scattered brown spots in <i>L. ventripunctata</i>), 1/3 toe webbing and wide toe lateral fringes (vs no toe webbing and no lateral fringes in <i>L. ventripunctata</i>), and distinct dermal ridges under toes (vs absent in <i>L. ventripunctata</i>). Furthermore, the dominant vocal frequencies of the new species range from 7.3 to 8.3 kHz, which is unique compared to other <i>Leptobrachella</i> species and represents the highest dominant frequencies ever recorded. The Shiwandashan National Nature Reserve is now home to four known sympatric species of <i>Leptobrachella</i>.

A new species of Leptobrachella, L. wumingensis sp. nov., was described from the Damingshan National Nature Reserve, Wuming District, Nanning City, Guangxi, China based on morphological, molecular and bioacoustic data. Phylogenetic analysis of 16S mtDNA fragments revealed that the new species is closely related to L. damingshanensis. Uncorrected p-distances between the new species and all homologous DNA sequences available for the 16S gene of Leptobrachella are greater than 7.1%. Morphologically, L. wumingensis sp. nov. differs from its congeners in several ways, including a medium body size (SVL 26.0–26.7 mm in males, 30.6–34.8 mm in females), lack of toe webbing and lateral fringes, shagreened and granular dorsal surface, pale brown dorsum with darker brown markings, iris bicolored, with the upper half copper and fading to silver in the lower half, and the presence of small irregular black spots and tangerine tubercles on the flanks. Furthermore, we found the new species to have two types of advertisement calls and relatively high dominant frequencies, making it distinct from its congeners.

The genus <i>Leptobrachella</i> (Anura, Megophryidae) was originally described, based on the type species from Sarawak (Malaysia), <i>Leptobrachella mjöbergi</i> Smith. The taxa in the group were previously classified into different genera, i.e, <i>Paramegophrys</i> Liu; <i>Leptolalax</i> Dubois; <i>Lalax</i> Delorme, Dubois, Grosjean & Ohler; and <i>Lalos</i> Dubois, Grosjean, Ohler, Adler & Zhao. However, Yuan et al. synonymised <i>Leptolalax</i> with <i>Leptobrachella</i> in 2017. Members of <i>Leptobrachella</i> inhabit the forest floor and rocky streams in hilly evergreen forests. They are widely distributed from southern China and Myanmar through mainland Indochina to Peninsular Malaysia and the island of Borneo. However, the species diversity of the genus was indicated to be underestimated by phylogenetic analyses and a series of new species have been discovered recently. In Vietnam, 34 species of <i>Leptobrachella</i> are currently known and 75% (or 24 species) have been described or newly recorded from the country since 2010.We describe a new species, <i>Leptobrachella huynhi</i> sp. nov., from Sin Ho District, Lai Chau Province. The new species is distinguished from its congeners by genetic divergences ranging from 3.62 to 18.51% (16S rRNA gene) and morphological differences: size medium (SVL 37.8–40.2 mm in adult females); head longer than wide; tympanum distinct; skin on entire dorsum shagreened; toes without webbing and with narrow lateral fringes; supratympanic ridge slightly rough with few nodules; dorsum grey-brown with indistinct dark brown markings; an interorbital region with a stacking double Y-shaped marking; centre of belly creamy-white, outer edges of belly brown with small whitish spots; iris copper. The new species is the 35th species of the genus <i>Leptobrachella</i> known from Vietnam.

Full textAbstract:
The species-rich, megophryid frog genus Leptobrachella Smith, 1925 is distributed throughout the uplands of mainland Southeast Asia but is conspicuously absent from the Cardamom Mountains of southwestern Cambodia, where it has been known only by a single, undetermined metamorphic specimen collected nearly two decades ago. We report two adult female specimens of Leptobrachella collected a decade later at a second locality in the Cardamom Mountains and use mitochondrial DNA, nuclear DNA, and morphology to show that it represents a distinct species. Leptobrachella neangi sp. nov., named after its collector, is most closely related in mitochondrial and nuclear DNA to L. fuliginosa (Matsui, 2006) and L. melanoleuca (Matsui, 2006) from western Thailand, but has uncorrected pairwise distances of 8.69–10.99% in a mitochondrial 16S gene fragment from its two sister species. The new species is also readily distinguished from these and other congeners by having the combination of (1) SVL 35.4–36.3 mm in two adult females, (2) distinct dorsolateral glandular line absent, (2) belly transparent, immaculate purplish gray in life, creamy white in preservative, (3) dark inguinal blotch absent, (4) tympanum with black coloration extending from line under supratympanic fold, (5) dorsal skin with small, irregular bumps and ridges, and (6) iris coppery orange around pupil, fading to gold at periphery, not distinctly bicolored. The new species is the first named Leptobrachella from the Cardamom Mountains and the third from Cambodia.

The Hoang Lien Range in northwest Vietnam is known to harbour five species of Leptobrachella, a specious genus of terrestrial frogs. We collected specimens of Leptobrachella from Mount Pu Ta Leng on the second highest peak in the Hoang Lien Range and use morphological and molecular data to show that this population represents a previously undescribed species which we name Leptobrachella graminicola sp. nov. after the abundance of calling males on sedge-like plants. This new species is closely related to L. bourreti but the new species is distinguished from L. bourreti and other congeneric species by a combination of the following characters: (1) a body size range of 23.1–24.6 mm in six adult males and 28.6–32.9 mm in five adult females; (2) skin on dorsum smooth, with many tubercles and lacking dermal ridges; (3) toes with rudimentary webbing and broad lateral fringes; (4) belly white with brown spots; (5) throat dark brown with light grey-brown flecks and spots; (6) a row of large white spots on the outer edge of the tarsus extending from the heel to the inner metatarsal tubercle, sometimes forming a long white stripe; and (7) a bicoloured iris. The new, high-elevation species is likely to be range-restricted and threatened by habitat loss and the activities of tourists.

Asian leaf-litter toads of the genus Leptobrachella represent charismatic anuran diversification with 80 species, of which 25 are from China. Recent new discoveries suggest that the diversity of this genus is underestimated. Here, we describe a new species of Leptobrachella, Leptobrachella bashaensis sp. nov. from the Basha Nature Reserve, Congjiang County, Guizhou Province, China. The new species is distinguished from its congeners by the following suite of morphological traits: small body size (SVL 22.9–25.6 mm in six adult males and 27.1 mm in one adult female); head longer than wide; dorsal skin slightly shagreened with small tubercles; creamy-white chest and belly with irregular black spots; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; iris bicolored with bright orange in upper half and silver in lower half; dorsal surface of tadpole head dark brown with small, brown, irregular spot, air sac-shaped bulges on both sides of body. The new species differs from all known congeners by an uncorrected p-distance of >5.3% of the 16S rRNA gene fragment examined, and the phylogenetic analysis clusters the new species with L. maoershanensis and L. laui. At present, the new species is only known from a small range of montane evergreen secondary forests in Basha Nature Reserve approximately 900 m elevation. Its natural history and conservation status are discussed.

Full textAbstract:
The uplift of the Qinghai-Tibet Plateau and the Indochina extrusion are two of the most prominent consequences of the India–Asia collision. These two geologic events greatly altered topography and drainage patterns that, in turn, affected the regional climate, the landscape and the evolution of biodiversity. Despite this, little is known about how orogeny and climate affect the evolution of biodiversity, especially the dynamics of diversification, including origins, peaks and endings. Here, we performed phylogenetic and biogeographic analyses of <i>Leptobrachella</i> distributed in Southeast Asia and southern China, based on mitochondrial 16S ribosomal RNA. The results revealed that <i>Leptobrachella</i> may be roughly divided into Clade I from south of the Indo-Burma and Clade II from central and northern Indo-Burma and southern China. We then investigated the diversification of <i>Leptobrachella</i> over time through biogeographic meta-analyses. We showed that the speciation of <i>Leptobrachella</i> was dominated by <i>in situ</i> diversification that was most likely associated with the uplift of the Qinghai–Tibet Plateau, the Indochina extrusion and the intensification of the Asian monsoon and that diversification may have been less influenced by temperature. <i>In situ</i> diversification experienced three small accelerated phases and one decelerated phase initiated at ~ 32 Ma, with a sharp increase at ~ 15 Ma, a peak at ~ 8.7 Ma and a gradual decline after ~ 6 Ma and the peaks of diversification were asynchronous in Southeast Asia and southern China. Our results suggest a three-phase scenario for the diversification of <i>Leptobrachella</i>, with periods of acceleration and deceleration at every stage, a pattern consistent with the Indochina extrusion, the uplift of the Qinghai–Tibet Plateau and the intensification of the Asian monsoon since the Oligocene. This study highlights how biogeographic meta-analyses can be utilised to estimate diversification history in taxa lacking sufficient molecular markers to quantify the impact of orogeny and climatic shifts on diversification processes. In addition, we also identified four undescribed species and described one new species, <i>Leptobrachella xishuiensis</i> sp. nov., from Xishui County, Guizhou Province, China.

We described a new species of the genus Leptobrachella from Southern Guangxi, China, based on morphological characteristics, molecular analyses and bioacoustics. This new species, Leptobrachella shiwandashanensis sp. nov., occurs in sympatry with Leptobrachella shangsiensis. However, phylogenetic analyses based on the mitochondrial 16S gene fragment revealed that the new species was clustered in a monophyletic group and a considerable genetic divergence existed between the new species and L. shangsiensis (p-distance: 7.9%) as well as its congeners (minimum p-distance: 7.0%). The new species also differed from its congeners by a combination of the following characteristics: (1) small size (SVL 26.8–29.7 mm in males; 33.7–35.9 mm in females); (2) pale brown dorsal surfaces, with a brown inverse-triangle-shaped marking between the eyes; (3) creamy white ventral surface with brown spots on the lateral margin, with a near immaculate creamy white throat and chest; (4) without webbing and lateral fringes on toes; (5) flanks with irregular black spots; (6) tibia-tarsal articulation reaching the posterior of the eye in males but reaching the shoulder in females; (7) heels that do not meet when the thighs are appressed at right angles to the body; (8) bicolored iris, with the upper half brownish-red, fading to silver in the lower half; and (9) a call consisting of a single note and a dominant frequency of 5.3–5.7 kHz (recorded at 23°C).

The Gaoligong Mountain Range in Yunnan Province, China, is characterized by its large variation in elevation and topography, together with its wide latitudinal range, resulting in extremely high levels of biodiversity. Studies show that the amphibian diversity of the Gaoligong Mountain Range is largely underestimated, especially in the south. During herpetological surveys in 2023 and 2024, three specimens of <i>Leptobrachella</i> were collected from the mountain at Tongbiguan Provincial Nature Reserve. Subsequent morphological comparisons and a phylogenetic reconstruction revealed that these specimens belonged to a previously unknown and morphologically distinct lineage of <i>Leptobrachella</i>, which we formally describe. Our discovery brings the number of species in the genus to 108, 44 of which occur in China, and seven on Gaoligong Mountain Range. This result confirms the underestimated amphibian diversity of the Gaoligong Mountain Range, especially in Tongbiguan Provincial Nature Reserve, where multiple sympatric congeneric species occur, including four species of <i>Leptobrachella</i>, five species and a putative new species of <i>Xenophrys</i>, and three species of <i>Polypedates</i>. These findings also highlight the need for future research to investigate the mechanisms of sympatric and syntopic coexistence.

A new leaf litter toad, <i>Leptobrachella yongshunensis</i> sp. nov., is described on the basis of morphological, acoustic, and molecular data in this study. The new species was distributed in Xiaoxi National Nature Reserve, Yongshun County, Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province, China. Phylogenetical analysis revealed that the new species is sister species of <i>L. wulingensis</i> (p-distance 0.019 in 16s rRNA gene, p-distance 0.073 in COI gene). The duration of advertisement call was 194.2 ± 6.7 ms, the mean dominant frequency of the first note was 3.885 ± 0.066 kHz, and the mean dominant frequency of the second note was 3.914 ± 0.052 kHz. The new species can be distinguished from its congers by the following morphological characters: snout-vent length (SVL) 27.2–28.9 in males, SVL 26.2–31.6 in females; black spots on flanks; toes webbing rudimentarily; narrow fringes on toes; creamy white ventral body with indistinct black speckling at margins; dorsal body with sparse large warts, dense little wart grains, and longitudinal ridges; head width greater than head length; tibiotarsal articulation reaching to anterior edge of the eye; brick-red color in the dorsal surface; upper parts of iris bright coppery in life. We still supplemented the molecular data of the COI gene of <i>L. wulingensis</i> for further research. The discovery of the new species not only enhances the species diversity of the Wuling Mountains, but also suggests the hidden species diversity in the area.

A new species of Leaf Litter Toad, Leptobrachella shimentaina sp. nov., is described from the Shimentai and Luokeng nature reserves of northern Guangdong Province, southern China. The new taxon can be distinguished from all recognized congeners by a combination of discrete morphological character state differences relating to its small body size (SVL 26.4–28.9 mm in six adult males, 30.1 and 30.7 mm in two adult females); a number of apparently fixed color pattern character differences (including eye coloration and color pattern features from dorsal, ventral, and dorsolateral surfaces of its head, body, limbs, and ventrum); the morphological and discrete characteristics of the external phenotype (the skin texture of dorsum and ventrum, the presence of supra-axillary and ventrolateral glands, the wide dermal fringes and rudimentary webbing on toes, and the uninterrupted longitudinal ridges under toes). Two samples of this new species previously were proposed as representing a new, unnamed species. We now substantiate this claim by providing diagnostic comparisons of discrete character differences. In addition, we also discuss taxonomic uncertainty surrounding the identity of two congeners, L. chishuiensis and L. purpurus, which we interpret as indicative of taxonomic inflation in the species-rich subfamily Megophryidae.

A new species of the Asian leaf litter toad genus <i>Leptobrachella</i>, <i>L. dayaoshanensis</i> sp. nov., is described based on phylogenetic analysis, morphological characters, and bioacoustic data. This species occurs in the Dayaoshan National Nature Reserve located in Jinxiu County, Guangxi, China. Phylogenetic analysis indicates that this new species is closely related to <i>L. verrucosa</i>, as demonstrated by phylogenetic trees. The new species can be distinguished from its congeners by a combination of the following characters: (1) medium size (mean snout–vent length (SVL) of 27.9 ± 0.7 mm, range 26.6–28.9 mm in males; 34.4 mm in female); (2) rough dorsal surface featuring small, raised tubercles and ridges; (3) flanks adorned with irregular black spots and creamy white glands; (4) creamy white ventral surface with sparse light-brown spots and irregular tiny textures; (5) brown throat and chest; (6) rudimentary toe webbing; (7) wide lateral fringes on toes; (8) distinct continuous ventrolateral glandular line; (9) tibiotarsal articulation reaching the midpoint of eye when the leg is extended forward; (10) heels that do not meet when thighs are appressed at right angles to body; (11) bicolored iris, with the upper half being copper and gradually transitioning to silver in the lower half; and (12) advertisement calls consisting of two model types, with dominant frequencies of 4.2–6.8 kHz at 21.0 °C. The new species has a breeding season that occurs from March to April and is found in evergreen forests at elevations between 1,000 and 1,600 m.

Full textAbstract:
The genus Leptobrachella (Anura, Megophryidae) was originally described, based on the type species from Sarawak (Malaysia), Leptobrachella mjöbergi Smith. The taxa in the group were previously classified into different genera, i.e, Paramegophrys Liu; Leptolalax Dubois; Lalax Delorme, Dubois, Grosjean & Ohler; and Lalos Dubois, Grosjean, Ohler, Adler & Zhao. However, Yuan et al. synonymised Leptolalax with Leptobrachella in 2017. Members of Leptobrachella inhabit the forest floor and rocky streams in hilly evergreen forests. They are widely distributed from southern China and Myanmar through mainland Indochina to Peninsular Malaysia and the island of Borneo. However, the species diversity of the genus was indicated to be underestimated by phylogenetic analyses and a series of new species have been discovered recently. In Vietnam, 34 species of Leptobrachella are currently known and 75% (or 24 species) have been described or newly recorded from the country since 2010. We describe a new species, Leptobrachella huynhi sp. nov., from Sin Ho District, Lai Chau Province. The new species is distinguished from its congeners by genetic divergences ranging from 3.62 to 18.51% (16S rRNA gene) and morphological differences: size medium (SVL 37.8–40.2 mm in adult females); head longer than wide; tympanum distinct; skin on entire dorsum shagreened; toes without webbing and with narrow lateral fringes; supratympanic ridge slightly rough with few nodules; dorsum grey-brown with indistinct dark brown markings; an interorbital region with a stacking double Y-shaped marking; centre of belly creamy-white, outer edges of belly brown with small whitish spots; iris copper. The new species is the 35th species of the genus Leptobrachella known from Vietnam.
