Abstract 
A new species of Amolops is described from Vu Quang National Park, Ha Tinh Province, North-central Vietnam based on morphological and molecular differences. Morphologically, Amolops minhlei sp. nov. is distinguishable from its congeners by a combination of the following morphological characteristics: SVL 31.8–35.8 mm in males, 36.7–45.8 mm in females; head longer than wide; vomerine teeth absent; snout long (SE/SVL 0.16–0.17 in males, 0.16 in females); tympanum distinct, round (TD/ED 0.41–0.42 in males, 0.40–0.43 in females); skin smooth; supratympanic fold indistinct; dorsolateral fold present; webbing formula I0–0II0–1/2III0–1/2IV1/2–0V; dorsum olive green or reddish brown with a few dark spots; a brown dorsolateral stripe extending from behind eye to above vent; dorsal surface of fore- and hind-limbs light grey with brown crossbars, throat, chest and belly white; males with external vocal sac and nuptial pad on finger I; and flanks grey brown with small white glandular spot. In phylogenetic analyses, the new species is strongly supported as a member of the A. monticola group. However, the new species differs from other members of the A. monticola group by 10.00–19.66% pairwise genetic divergence in the mitochondrial ND2 gene fragment and 1.56–6.67% in the mitochondrial 16S gene fragment.

Nagaland Cascade Frog  ||  https://recordsofzsi.com/index.php/zsoi 

Abstract
The Asian cascade-dwelling frog genus Amolops currently comprises 90 recognised species, with 20 species reported from India. These species are generally classified into ten species groups based on morphological similarities, of which in India, Amolops species are mainly categorised across three groups: A. marmoratus group, A. monticola group and A. viridimaculatus group, with the first group being the most diverse, represented by eight species. Previous studies on the A. indoburmanensis species group and A. marmoratus species group suggest a species complex encompassing multiple cryptic lineages. Between 2022 and 2024, many Amolops specimens tentatively assigned to A. indoburmanensis sensu lato were collected from different parts of North-East India. Morphological variations and molecular phylogenetic analyses revealed multiple distinct lineages within this complex, confirming the paraphyly of the nomen A. indoburmanensis. Herein, we describe a new Amolops species belonging to the A. indoburmanensis species complex from North-East India, Amolops kamal sp. nov. from Nagaland state. The study underscores the rich hidden diversity within the Amolops genus and highlights the importance of integrated morphological and molecular approaches in resolving amphibian taxonomy in the region.

[Herpetology • 2026] Amolops guangzhouensis • A New Species of Amolops Cope, 1865 (Anura: Ranidae) from central Guangdong, China


Amolops guangzhouensis  
Song, F.-X. Wang, Qi, H.-T. Wang, Lyu, Cai, Zhu, Zhong, Liu & Y.-Y. Wang, 2026

 
Abstract
In this study, a new species of the genus Amolops (Anura, Ranidae), Amolops guangzhouensis sp. nov., is described based on six type specimens collected from Conghua District, Guangzhou City, and adjacent Longmen County, Huizhou City, in Guangdong Province, China. The molecular phylogenetic analysis, based on two mitochondrial DNA fragments (16S and COI), places the new species as an independent evolutionary lineage within the A. daiyunensis group. The morphometric statistical analysis and morphological comparison also distinguish the new species from all other congeners. This species can be differentiated from those close relatives by dorsal surface pattern, tiny translucent white spinules across skin, indistinct supernumerary tubercle below fingers, prominent tarsal gland and tarsal fold, and nuptial pad coloration. The discovery of this new species adds to the growing diversity of this genus and represents the westernmost distribution occurrence of the A. daiyunensis group, implying the species diversity of Amolops in southeastern China might still be underestimated.

Abstract
Species discovery within Odorrana has gradually increased over the years, establishing a remarkable diversity for the genus. During recent herpetological surveys, we collected specimens from Yingjiang County, Yunnan Province, China with additional samples from Thailand and Vietnam. Based on combined morphological and phylogenetic analyses, we describe a new species Odorrana sudianensis sp. nov. from Sudian Town, Yingjiang County, China and report new records of O. heatwolei for Thailand and Vietnam. Phylogenetic analyses, based on the 16S rRNA mitochondrial gene fragment, confirm the new species as a distinct evolutionary lineage with a genetic divergence (p-distance) of 4.6% from its closest sister species O. dulongensisOdorrana sudianensis sp. nov. is morphologically distinguishable from all its known congeners by having a robust medium adult body size, a head length longer than wide, a mottled grass-green dorsum with dark brown blotches on the posterior region, absence of dorsolateral folds and circum-marginal grooves for all finger discs expanded with lateroventral grooves. Additionally, the new species record sequences from Thailand and Vietnam nested within the O. heatwolei subclade with a low p-distance (0.0–0.5%) from topotypic sequences of O. heatwolei. Examined specimen shows morphological congruence with topotypic O. heatwolei in key diagnostic traits. Our new species and new species records increase the number of recognised species of Odorrana to 46 in China, seven in Thailand and 23 in Vietnam. We also address existing taxonomic disputes within Odorrana and provide comments and recommendations on the taxonomy of several species within the genus.

Amolops cuongi 
Pham, Hoang, Tapley, L. T. Nguyen, H. H. Nguyen, La, Ziegler, Rowley, T. Q. Nguyen & Le, 2025  
 

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.

Odorrana liboensis 
Luo, S. Wang, Xiao, Y. Wang & Zhou, 2021


Abstract
We describe Odorrana liboensis sp. nov., a new species from the Maolan National Nature Reserve, Libo County, Guizhou Province, China. Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA, 16S rRNA, and ND2 genes supported the new species as an independent lineage, closely related to O. lipuensis. The uncorrected genetic distances between the 12S rRNA and 16S rRNA in the new species and its closest congener, O. lipuensis, were 6.06% and 5.19%, respectively. The new species is distinguished from its congeners by a combination of the following morphological characters: (1) having medium body size, with the snout-vent length (SVL) of adult females approximately 1.2 times as long as males at 56.9 ± 1.0 (55.8–58.2 mm, n = 9) in females and 48.7 ± 1.2 (47.1–49.9 mm, n = 5) in males; (2) head length greater than width in males and females; (3) tympanum distinctly visible, greater than one-half the diameter of the eye; (4) eyes big and prominent, width of upper eyelid (UEW) approximately 3/4 of eye diameter (ED); (5) dorsolateral folds absent; (6) two metacarpal tubercles; (7) relative finger lengths: II < I < IV < III; (8) subarticular tubercles on fingers prominent: 1, 1, 2, 2; (9) one metatarsal tubercle; (10) tibiotarsal articulation reaching to between the eye and nostril when the leg is stretched forward; (11) toes with entire webbing to disks; (12) subarticular tubercles on toes prominent: 1, 1, 2, 3, 2; (13) dorsal surfaces of limbs with distinct brownish-black bands; (14) smooth, grass-green dorsum with irregular brown mottling; (15) venter smooth, lacking black spots; and (16) lacking pectoral spinules, lacking vocal sacs, and light white nuptial pad present on finger I in males. The new species is currently only known from the type locality.

[Herpetology • 2025] Odorrana calciphila • Definition and Taxonomic Revision of the Karst-associated Odorrana lipuensis Group (Anura: Ranidae), with A New Species from Guangdong, China


 Odorrana calciphila Song, Qi, Wang, Liu & Wang, 

in Song, Qi, H.-T. Wang, Gong, Liu et Y.-Y. Wang, 2025.

Abstract
While taxonomy of the odorous frog genus Odorrana has made considerable progress recently, far less attention was given to those newly-described karst-associated species. In this study, the taxonomic status of Odorrana lipuensis group, species living in karst environments, was revisited. Combining the scrutiny of previous literature, molecular analyses using two mitochondrial DNA fragments (i.e. 16S rRNA and CO1) and morphological analyses including a series of additional specimens, we defined the O. lipuensis group and revised the taxonomic accounts of recognised species. Based on these data, we described a new species, O. calciphila sp. nov. from the karst regions in northern Guangdong, China. Apart from this new species, the O. lipuensis group currently contains three other species distributed in southern China and northern Vietnam, namely O. concelata, O. liboensis and O. lipuensis. Morphological comparisons between this group and other congeners, together with a dichotomous identification key for each species within this group, were also presented. Finally, the known distribution, implications of morphological distinctiveness, ecological and evolutionary significances and existing taxonomic issues of these species were also discussed.

Abstract
A new species of the genus Nidirana Dubois, 1992 is described from Cangshan Mountain, Dali Prefecture, Yunnan Province, China. The new species is morphologically most similar to N. pleuraden (Boulenger, 1904) and N. occidentalis Lyu, Yang & Wang, 2020, but it can be distinct from the latter two species by having a relatively shorter and wider head, relatively larger eyes, relatively smaller tympana, relatively much shorter foot, and a much greater difference in body size between males and females. Phylogenetically, the new species differs from its congeners by a genetic divergence of 2.6–8.6% and 6.1–14.1% in 16S and COI genes, respectively. This study further emphasizes that the diversity of the genus Nidirana is still severely underestimated.

Nidirana cangshanensis sp. nov.

Diagnosis. Body size medium, SVL 43.6–52.1 mm in adult males and 59.7–64.1 mm in adult females; head relatively short, HDL/SVL 0.34–0.36; head length approximately equal to head width, HDL/HDW 0.99–1.05; eye relatively large, ED/HDL 0.29–0.33; tympanum relatively small, TD/HDL 0.17–0.20, TD/ED 0.52–0.71; tip of every digit not dilated; lateroventral groove absent on every digit; foot short, FTL/SVL 0.52–0.57; tibio-tarsal articulation reaching between tympanum and eye or at eye; heels just meeting; posterior of dorsal skin rough with tubercles; a pair of subgular vocal sacs in breeding males; single nuptial pad present on first finger in adult males; suprabrachial gland large and smooth.

Etymology. The specific name cangshanensis refers to the type locality Cangshan Mountain, in Dali Prefecture, Yunnan Province, China. We suggest the English common name to be “Cangshan Mountain Music Frog” and the Chinese common name to be “苍山琴蛙 (Pinyin: cāng shān qín wā)”.

[Herpetology • 2020] Nidirana occidentalis • A New Species of Nidirana from the N. pleuraden Group (Anura: Ranidae) from western Yunnan, China


Nidirana occidentalis  Lyu, Yang & Wang,

 in Lyu, Chen, Yang, ZENG, J. Wang, Zhao, Wan, Pang et Y.-Y. Wang, 2020.
 
Abstract
The Music Frog genus Nidirana was recently resurrected as a distinct genus and contains 14 species distributed in subtropical eastern and southeastern Asia. The species diversity of Nidirana is dramatically underestimated, and half of its species was described in the last five years. In this study, Nidirana occidentalis sp. nov., a new species of Music Frog from western Yunnan, China, is proposed based on morphological and molecular evidences. The new species was previously misidentified as N. pleuraden, but can be distinguished from the true N. pleuraden from eastern Yunnan, and all other congeners, by a combination of morphological characteristics, and significant divergence in the mitochondrial genes (≥ 5.1% in 16S and ≥ 8.9% in CO1). Nidirana occidentalis sp. nov. is assigned to the N. pleuraden group on the basis of morphological characters, but its phylogenetic placement remains unresolved due to weak branch support. Geographically, these two species are isolated by the Red River in Yunnan, supporting the hypothesis that the Red River is an important geographical barrier that drives speciation in flora and fauna. Nidirana occidentalis sp. nov. represents the second species of N. pleuraden group and the 15th species of the genus.

Abstract
Of the 19 species of Amolops reported from Vietnam, 10 are known to occur in the Hoang Lien Range in northwest Vietnam. During field surveys in the Hoang Lien Range, we collected individuals from a population of Amolops that we could not assign to any known species; morphological and molecular data assign these individuals to the Amolops monticola group and we describe a new species to science, Amolops spicalinea sp. nov., in reference to a line of horny spinules running along the body below the dorsolateral fold in males. The new species is morphologically and molecularly most similar to Amolops bellulus from Yunnan Province, China but is distinguished from A. bellulus and other congeneric species by a combination of the following characters: (1) SVL of adult males 46.6–52.2 mm, N=3; adult females 60.1–63.0 mm, N=3; (2) vomerine teeth in two oblique rows between choanae; (3) tympanic annulus visible; (4) all finger and toe tips expanded to discs with circummarginal grooves present; (5) skin smooth, except for lateral surfaces of head, below the dorsolateral fold, and the area surrounding cloaca where the texture varies from tiny spinules to large tubercles; (6) dorsolateral fold present with horny spinules along the lower half in males; (7) creamy-white lip stripe extending from tip of snout, terminating in a broken, rugose line above axilla; (8) dorsum reddish brown or greenish brown with numerous small black spots; flanks yellowish brown to dark brown; ventral surface of body orange-yellow with small brown spots present on chest and throat; (9) interdigital finger webbing absent; toes fully webbed to discs except on Toes IV where webbing reaches discs as a fringe, webbing formula: I0–0II0–0III0–1+IV1+–0V; (10) outer metatarsal tubercles absent; (11) vocal sac absent in males, and (12) nuptial pad velvety without spines. Our phylogenetic analysis using 16S ribosomal RNA mitochondrial gene and cytochrome c oxidase subunit 1 (CO1) genes show that Amolops spicalinea sp. nov. is sister to Amolops bellulus 2 from Yunnan, China. The new species is currently known from only three localities in the Hoang Lien Range between 2288–2493 m asl and is threatened by habitat loss and degradation. This species likely qualifies for being assessed as Endangered in accordance with the IUCN Red List of Threatened Species categories and criteria (B1ab).

 Amolops spicalinea sp. nov.

Diagnosis. Amolops spicalinea sp. nov. is placed within the Amolops monticola group based on the following morphological characters: Finger I shorter than Finger II; true dorsolateral folds present (not formed by incomplete series of glands); skin smooth; lateral sides of head dark, with light-colored upper lip stripe extending to shoulder (jiang et al. 2021; Patel et al. 2021; Stuart et al. 2010; wu et al. 2020). the new species can be diagnosed from congeneric  species  by  the  combination  of  the  following  characters:  (1)  SVL  of  adult  males  46.6–52.2  m, N=3; adult females 60.1–63.0 mm, N=3; (2) vomerine teeth in two oblique rows between choanae; (3) tympanic annulus visible; (4) all finger and toe tips expanded to discs with circummarginal grooves present; (5) skin smooth, except for lateral surfaces of head, below the dorsolateral fold, and the area surrounding cloaca where the texture varies from tiny spinules to large tubercles; (6) dorsolateral fold present with horny spinules along the lower half in males; (7) creamy-white lip stripe extends from the tip of the snout terminating in a broken, rugose line above axilla; (8) dorsum reddish brown or greenish brown with numerous small black spots; flank yellowish brown to dark brown; ventral surface orange-yellow with brown spots present on chest and throat; (9) interdigital finger webbing absent; toes fully webbed to discs except on toes IV where the webbing reaches the discs as a fringe, webbing formula: I0–0II0–0III0–1+IV1+–0V; (10) outer metatarsal tubercle absent; (11) males vocal sacs absent, and (12) nuptial pad velvety without spines.
 
Etymology: Specific epithet “spicalinea” from spica, the Latin word for a point or ear of grain and lineata, the Latin noun meaning line or thread in reference to the line of spinules running along the body, below the dorsolateral fold in males. We suggest common name as Hoang Lien cascade frog (English) and Ếch bám đá hoàng liên sơn (Vietnamese).
