Abstract: A new species of Odorrana is described from the limestone karst forest in northern Vietnam based on morphological differences and molecular divergence. Morphologically, Odorrana nagao sp. nov. is distinguishable from its congeners by the following combination of characteristics: size medium (SVL 37.4 mm in male, 47.1–54.7 mm in females); head longer than wide; tympanum distinct, round, ~50% of the diameter of eye; vomerine teeth present; males without external vocal sac; nuptial pad present on finger I in males; webbing formula I0–1II0–1III0–11/3IV11/3–1/4V; tibio-tarsal articulation reaching the tip of snout when hindlimb adpressed along body; dorsolateral conical spines present; dorsolateral fold present; dorsum moss-green with brown mottling; ventral surface cream with dark brown mottling. Phylogenetic analyses of mitochondrial 16S rRNA and COI gene sequences supported the new species as a sister taxon to an unresolved clade consisting of Odorrana calciphila, O. concelata, O. feii, O. liboensis and O. lipuensis (UFB = 98, PP = 1). The uncorrected p-distances of 16S rRNA and COI genes between the new species and its closest congeners were 2.33% and 6.33%, respectively.

Abstract: A new subspecies of Amolops dafangensis Li, Liu, Ke, Cheng, & Wang, 2024, designated as Amolops dafangensis wumengmontis ssp. nov., is described from Mt. Wumeng, Zhaotong City, northeastern Yunnan, China, based on phylogenetic analysis of the 16S rRNA and CO1 genes, as well as morphological examinations. Phylogenetic analysis indicated that specimens from the Wumeng Mountains clustered within Amolops dafangensis, forming two main clades within this species. Amolops dafangensis wumengmontis ssp. nov. demonstrates a close phylogenetic relationship with A. d. dafangensis and is differentiated from the nominal subspecies by specific characteristics: 1) tympanum indistinct; 2) tibiotarsal articulation just reaching anterior corner of the eye; 3) flat and indistinct inner and outer metacarpal tubercles; and 4) webbing formula: I1–1II1–1½III1–2IV2–1V.

Abstract: A new species of the genus Amolops is described from the Hoang Lien Range, northwestern Vietnam as Amolops cuongi sp. nov. While morphological and molecular data assign these individuals to the Amolops mantzorum group, the new species is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: size small (SVL 33.9–36.9 mm in males; 37.9–44.4 mm in females); head longer than wide; vomerine teeth absent or weakly developed; snout short (SE/SVL 0.15–0.17 in males; 0.14–0.16 in females); tympanum small (TD/ED 0.26–0.37 in males; 0.25–0.35 in females); the absence of circummarginal groove on the first finger; disc of finger III larger than tympanum; supratympanic fold present; dorsolateral fold absent; webbing formula I0–1II0–1III0–1IV1–0V; the presence of a band of small spinules and/or tubercles running from below nares, along upper lip, around lower half of eye, between tympanum and eye and rear axis of mandibles; granular skin on flanks and ventral surfaces of body; in life, dorsal body colouration of dark brown with diffuse-edged blotches of bluish grey, copper and yellowish green or pale green and copper; ventral surface of throat, chest and belly pale cream with white dots; males without vocal sacs; and nuptial pad velvety without spines. In the phylogenetic analysis using a combination of mitochondrial 16S ribosomal RNA, ND2, and cytochrome b (cyt b) genes, the new species is strongly supported as the most genetically distinct member of the Amolops mantzorum group with genetic distance ≥ 1.53% in the 16S rRNA, ≥ 8.70% in ND2, and ≥ 8.56% in cyt b compared to other members within the genus Amolops.

Abstract: Nidirana okinavana (Boettger, 1895) is a small-sized ranid species belonging to the East Asian genus Nidirana Dubois, 1992. Previous studies have indicated that this species was exclusively distributed on Ishigaki and Iriomote islands in the southern Ryukyus, as well as two extremely small wetland habitats in central Taiwan. Such a restricted distribution makes it one of the most endangered frog species in both Taiwan and Japan. By using molecular, morphological, and acoustic analyses, our study reveals significant divergence between the Taiwanese and Japanese clades, supporting the recognition of the Taiwanese clade as a distinct species, described herein as Nidirana shyhhuangi sp. nov. Compared to Nidirana okinavana sensu stricto from the southern Ryukyus, the Nidirana shyhhuangi sp. nov. is characterized by a significantly smaller and non-overlapping body size, relatively longer forelimbs and hindlimbs, smaller internostril and interorbital distances, with a higher number of cross bands on thigh and shank. Acoustic analyses reveal that the Nidirana shyhhuangi sp. nov. produces calls with a rapid tempo and higher pulse number, with a higher dominant frequency compared to the Japanese clade. Due to the extremely limited distribution of this species to two small sites on Taiwan, and continuing decline in quality of its habitat, we propose that it should be classified as Critically Endangered (CR) under the IUCN criteria. Immediate and comprehensive in situ and ex situ conservation actions are necessary to ensure the sustainable viability of the population.

Abstract: The Gaoligong Mountains lie at the intersection of three global biodiversity hotspots. In recent years, with the continuous deepening of fieldwork in the region, studies have increasingly indicated that the amphibian diversity of this region remains poorly understood. During herpetological surveys in 2023, a series of Amolops specimens were collected from the Gaoligong Mountains of Yunnan Province, China. The integrated results of morphological and molecular phylogenetic analyses indicate the presence of a separate and previously unknown lineage in the A. viridimaculatus group, which we herein confirm as a new species, Amolops gudao Yu, Wu, Lu & Che, sp. nov. Our discovery increases the number of Amolops species recorded in China to 59, and the total number of Amolops species to 86. The discovery of a new species in the Gaoligong Mountains further highlights the underestimated amphibian diversity in the region, emphasizing the need for continued fieldwork and research. Furthermore, Amolops gudao Yu, Wu, Lu & Che, sp. nov. exhibits obvious intraspecific variation in color patterns, a phenomenon also reported in several species within the A. viridimaculatus group, such as A. viridimaculatus and A. kaulbacki. Future studies on the taxonomy of A. viridimaculatus group should be careful with the use of color patterns as a diagnostic characteristic.

Abstract: Mitochondrial genomes (also known as mitogenomes) serve as valuable molecular markers and have found widespread applications in molecular biology and ecology. There is abundant sequence variation in vertebrate mitogenomes, and occasionally, they exhibit gene rearrangements. In this study, two Chinese endemic Rana species, Rana jiemuxiensis and Rana hanluica, were sequenced and analyzed to obtain their complete mitogenomes. The two species were sympatrically distributed in the Zhangjiajie National Forest Park, in Wulingyuan District, Zhangjiajie City, Hunan Province, China. The mitogenome of R. jiemuxiensis was 17,506 bp, while that of R. hanluica was 17,505 bp, each comprising 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a non-coding control region (D-loop). The gene content, nucleotide composition, and evolutionary rates of each mitogenome were analyzed and compared with those of congeners. A phylogenetic analysis based on 22 mitogenomes in Rana revealed that the two sympatric species were in two different lineages, indicating that they were genetically separated to a certain extent. Three types of gene rearrangement patterns were identified when examining the gene orders of the 22 Rana mitogenomes. Most of the species shared a second and dominant gene rearrangement pattern that originated from the first ancient pattern. A “tandem duplication – multiple deletion” hypothesis was proposed to explain the evolution of these different gene rearrangement patterns. This study provided valuable data references and enhanced our understanding of the phylogenetic implications and gene rearrangements of Rana species.

Abstract: The frog genus Odorrana is distributed across east and southeastern Asia. Based on morphological differences and molecular phylogenetics, a new species of the genus occurring from Leigong Mountain in Guizhou Province, China is described. Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA, 16S rRNA, and ND2 genes supported the new species as an independent lineage. The uncorrected genetic distances between the 12S rRNA, 16S rRNA, and ND2 genes between the new species and its closest congener were 5.0%, 4.9%, and 16.3%, respectively. The new species is distinguished from its congeners by a combination of the following characters: body size moderate (SVL 39.1–49.4 mm in males, 49.7 mm in female); head width larger than head length; tympanum distinctly visible; small rounded granules scattered all over dorsal body and limbs; dorsolateral folds absent; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between eye to nostril when leg stretched forward; vocal sacs absent in male and nuptial pads present on the base of finger I.

Abstract: A new species of odorous frog, Odorrana damingshanensis sp. nov., was found at the Damingshan National Nature Reserve in Guangxi, China. This species can be distinguished from its congeners by a combination of the following characters: medium body size (SVL 52.3–54.8 mm in males and 74.8–81.2 mm in females), sawtooth spinules on the upper lip, obtusely rounded snout that extends beyond the lower margin, distinct dorsolateral folds, horny tubercles on the rear of the back, presence of outer metatarsal tubercles, dilated nuptial pad with velvety spinules, distinct maxillary gland with tiny spines, and external lateral vocal sac. Through analysis of the 16S mitochondria gene, the new species is closely related to O. nasica and O. yentuensis, but the genetic divergence between the new species and the latter exceeds 7% (uncorrected p-distance). Currently, the new species is only known from its original discovery site. Furthermore, a discussion on the taxonomy of Odorrana (Bamburana) was conducted, identifying seven species within the subgenus Odorrana (Bamburana).

Abstract: The Torrent frogs of the genus Amolops are widely distributed in Nepal and northern India eastwards to southern China and southwards to Malaysia. The genus currently contains 84 species. Previous studies indicated underestimated species diversity in the genus. In the context, a new species occurring from the mountains in the northwestern Guizhou Province, China is found and described based on morphological comparisons and molecular phylogenetic analyses, Amolops dafangensis sp. nov. Phylogenetic analyses based on DNA sequences of the mitochondrial 16S rRNA and COI genes supported the new species as an independent lineage. The uncorrected genetic distances between the 16S rRNA and COI genes in the new species and its closest congener were 0.7% and 2.6%, respectively, which are higher than or at the same level as those among many pairs of congeners. Morphologically, the new species can be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 43.2–46.8 mm in males); head length larger than head width slightly; tympanum distinct, oval; vocal sacs absent; vomerine teeth present; dorsolateral folds weak formed by series of glands; nuptial pads present on the base of finger I; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level far beyond the tip of the snout when leg stretched forward.

Abstract: A new species of music frog, Nidirana guibeiensis sp. nov., is described from northern Guangxi, China. Based on two mtDNA fragments analyzed, phylogenetic trees reveal that N. guibeiensis sp. nov. is most closely related to N. leishanensis. However, the new species can be identified by conspicuous diagnostic morphological characteristics as well as bioacoustics. In contrast to the known Nidirana species, the advertisement calls of the new species can be divided into three types, calls with one, two, and three notes. In addition, the new species has nest construction behavior, which is inconsistent with N. leishanensis. Nidirana guibeiensis sp. nov. occurs in paddy fields or still pools at 300–1300 m a.s.l.

Abstract: Karstic landscapes play an important role in biodiversity formation and often contain high levels of endemism. However, site-endemic taxa in karstic landscapes are being threatened by exploitation and weak legal protection. In this study, we describe Odorrana concelata Wang, Zeng, & Lin, sp. nov., a limestone karst-restricted odorous frog from northern Guangdong, China. This new species shows distinctive genetic divergence and morphological differences from its congeners. Phylogenetic results suggest that the new species represents an independent lineage that is grouped with O. lipuensis and O. liboensis based on the mitochondrial 16S and 12S ribosomal RNA genes. We recommend the new species be listed as Vulnerable (VU) in the IUCN categorization as it is only known from the type locality with limited microhabitats and is threatened by habitat degradation.

Abstract: It was supposed that the current records of Amolops ricketti might be a species complex composed of multiple species. In this study, on the basis of wide sampling, we found that the records of A. ricketti from Yunnan, China, and northern Vietnam actually represent a cryptic species based on morphological and molecular evidence. Amolops shihaitaoi sp. nov. can be distinguished from other members of the A. ricketti species group by its moderate body size (SVL 35.5‒37.3 mm in males and 39.2‒45.7 mm in females); white spines on the temporal region, loreal region, snout, and lips in breeding males but absent in females; overlapping heels; tibiotarsal articulation reaching tip of snout; indistinct longitudinal glandular folds on the skin of the shoulders; presence of supernumerary tubercles below the base of fingers II‒IV, distinct pineal body; presence of vomerine teeth; and absence of vocal sacs. Phylogenetic analysis supports that the new species is sister to Amolops yatseni and the populations from Jingxi, Guangxi and Lào Cai, Vietnam previously reported as A. yatesni also belong to it. Additionally, our results indicate that more cryptic species may exist within the A. ricketti species group, implying that more studies are needed to achieve a complete understanding of the species diversity of this group.

Abstract: Nidirana guangxiensis sp. nov., a new music frog species, is proposed, based on a series of specimens collected from Mt Daming, Guangxi, southern China. The new species is close to N. yeae, N. daunchina, N. yaoica, and N. chapaensis from southwestern and south-central China and northern Indochina, while the relationships among these species remain unresolved. Nidirana guangxiensis sp. nov. can be distinguished from all known congeners by the genetic divergences in the mitochondrial 16S and COI genes, the behavior of nest construction, the advertisement call containing 6–11 rapidly repeated regular notes, and a combination of morphological characteristics. Furthermore, the Nidirana populations recorded in Guangxi are clarified in this work, providing valuable new information on the knowledge of the genus Nidirana.

Abstract: A new species, Odorrana sangzhiensis sp. nov., is described, based on five specimens from Sangzhi County, Zhangjiajie City, Hunan Province, China. Molecular phylogenetic analyses, based on mitochondrial 12S rRNA and 16S rRNA gene sequences, strongly support the new species as a monophyletic group nested into the O. schmackeri species complex. The new species can be distinguished from its congeners by a combination of the following characters: (1) body size medium (SVL: 42.1–45.1 mm in males, 83.3–92.7 mm in females); (2) dorsolateral folds absent; (3) tympanum diameter 1.53 times as long as the width of the disc of finger III in females; 2.3 times in males; (4) dorsal skin green with dense granules and sparse irregular brown spots; males with several large warts on dorsum; (5) two metacarpal tubercles; (6) relative finger lengths: I ≤ II < IV < III; (7) tibiotarsal articulation beyond the tip of the snout; (8) ventral surface smooth in females; throat and chest having pale spinules in adult males; (9) dorsal limbs green or yellow green with brown transverse bands; and (10) paired external vocal sacs located at corners of the throat, finger I with light yellow nuptial pad in males. This discovery increases the number of Odorrana species to 59 and those known from China to 37.

Abstract: Three cryptic species, which were previously reported as Nidirana adenopleura, are revealed on the basis of comprehensive approaches. Nidirana guangdongensis Lyu, Wan, and YY Wang, sp. nov. is distributed in Nanling Mountains and southern Luoxiao Mountains, Nidirana mangveni Lyu, Qi, and YY Wang, sp. nov. is known from northern Zhejiang, and Nidirana xiangica Lyu and YY Wang, sp. nov. occurs in Xiangjiang River Basin, while the true Nidirana adenopleura is designated from Taiwan Island, northern Fujian, southern Zhejiang, and central Jiangxi. These three new species can be distinguished from all congeners by significant divergences in the mitochondrial 16S and CO1 genes, differences in advertisement calls, and the combination of multiple characteristics. This work indicates that the current records of Nidirana adenopleura should be of a species complex composed of multiple species and have clarified the true identity of N. adenopleura.

Abstract: Lithobates warszewitschii is a species of ranid frog distributed from southern Honduras to Panama. This species suffered severe population declines at higher elevations (above 500 m a.s.l.) from the 1980s to early 1990s, but there is more recent evidence of recovery in parts of its range. Here we advocate for the status of Lithobates warszewitschii as a candidate cryptic species complex based on sequence data from mitochondrial genes CO1 and 16S. Using concatenated phylogenies, nucleotide diversity (K2P-π), net between group mean distance (NBGMD) (πnet) and species delimitation methods, we further elucidate cryptic diversity within this species. All phylogenies display polyphyletic lineages within Costa Rica and Panama. At both loci, observed genetic polymorphism (K2P-π) is also high within and between geographic populations, surpassing proposed species threshold values for amphibians. Additionally, patterns of phylogeographic structure are complicated for this species, and do not appear to be explained by geographic barriers or isolation by distance. These preliminary findings suggest L. warszewitschii is a wide-ranging species complex. Therefore, we propose further research within its wider range, and recommend integrative taxonomic assessment is merited to assess species status.

Abstract: Two cryptic species, which were previously reported as Amolops ricketti, are revealed on the basis of significant morphological and genetic divergences. Amolops sinensis sp. n. from central Guangdong, northeastern Guangxi and southwestern Hunan can be distinguished by the longitudinal glandular folds on the skin of the shoulders and other character combinations. Amolops yatseni sp. n. from the coastal hills of west Guangdong can be distinguished by the dense tiny round translucent, or white, spines on the dorsal skin of the body, dorsal and dorsolateral skin of the limbs, and other character combinations. The phylogenetic interrelationships of the A. ricketti group have been inferred as (A. wuyiensis + A. ricketti) + (A. yunkaiensis + (A. albispinus + (A. sinensis sp. n. + A. yatseni sp. n.))). This work indicates that the current records of A. ricketti might be a species complex composed of multiple species, and further work is needed to figure out this puzzle.

Abstract: A new species of brown frog Rana luanchuanensis Zhao & Yuan, sp. n. is described from Luanchuan County, western Henan, central China. The mitochondrial genealogy suggests that the new species is the sister taxon to the clade including R. amurensis and R. coreana, and is separated by uncorrected pairwise distances more than 12.5%. Morphologically, this new species differs from its congeners by a suite of characters. Analyses of partial sequences of cytochrome oxidase subunit I (COI) resolve the new species as a single matriline.
