In this study, a new species of the genus Boulenophrys is described from northwestern Guangdong, within the Nanling Moutains. The new species can be distinguished from all known congeners by a combination of morphological characteristics and the mitochondrial genetic divergence. The new species is found to breed in winter season which was not common in most amphibian groups but also present in some Boulenophrys congeners.

A new species of the genus is described from the coastal hills of eastern Fujian Province, China. The new taxon can be distinguished from all recognized congeners by a combination of discrete morphological character state differences and genetic divergences in the combined mitochondrial 16S + CO1 genes. We also provide a map showing the distribution pattern of species in Fujian and a provincial-specific key, which will aid their conservation by helping the local authorities accurately identify species during field identifications and data collection efforts.

In order to cope with the complexity and variability of the terrestrial environment, amphibians have developed a wide range of reproductive and parental behaviors. Nest building occurs in some anuran species as parental care. Species of the Music frog genus Nidirana are known for their unique courtship behavior and mud nesting in several congeners.

The subfamily Megophryinae, as a representative batrachian group of the Oriental Realm and one of the most diverse groups of amphibians, has attracted considerable attention due to continued conjecture regarding its generic classification and failure to reach a satisfactory consensus. China boasts the richest diversity of Asian horned toads, containing some two thirds of the total species cataloged. However, most species have a complicated taxonomic history, resulting in multiple misidentifications.

Article Synopsis
  • Karstic landscapes are crucial for biodiversity but face threats from exploitation and inadequate legal protection, impacting site-endemic species.
  • The study identifies a new species of limestone karst-restricted odorous frog from northern Guangdong, China, which has unique genetic and physical traits compared to related frogs.
  • Researchers recommend classifying this new frog species as Vulnerable on the IUCN list due to its limited habitat and risk of habitat degradation.

Article Synopsis
  • The hilly region of eastern Guangdong, China has lacked thorough scientific research on its herpetofauna for many years, particularly concerning amphibians.
  • Recently, three new species of the genus Boulenophrys were identified, specifically from limited locations in this area, which highlights the region's biodiversity.
  • However, the rich diversity of amphibians is at risk due to habitat degradation and fragmentation, necessitating immediate conservation efforts.

The diversity of Panophrys horned toads is considered highly underestimated with a large number of undescribed cryptic species. In this work, we describe four Panophrys species from eastern China which were proposed as cryptic species by molecular data in previous study, additionally provide new information on the biogeography of these four species. Panophrys daiyunensis sp.

Two new toad species of the genus are described from the Yunnan-Guizhou Plateau of China, based on the combination of molecular and morphological data. The description of Wang, Lyu, Qi & Wang, from Huanglianshan Nature Reserve represents the thirteenth species known from Yunnan Province, and the description of Wang, Lyu, Qi & Wang, from Yushe Forest Park represents the sixth species known from Guizhou Province. These new discoveries further emphasize the extremely high diversity of the toads in these regions.

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.

A new species of colubrid snake, , is described based on two adult male specimens collected from Huaping Nature Reserve, Guangxi, southern China. In a phylogenetic analyses, the new species is shown to be a sister taxon to the clade composed of and with low statistical support, and can be distinguished from all known congeners by the significant genetic divergence in the mitochondrial cytochrome gene fragment (-distance ≥ 7.9%), and morphologically by the following combination of characters: (1) dorsal scales in 17-17-15 rows, smooth throughout; (2) supralabials eight, third to fifth in contact with eye, infralabials nine; (3) ventral scales 199-200 (plus two preventral scales), subcaudals 78; (4) loreal single, elongated, in contact with eye or not, not in contact with internasals; (5) a single preocular not in contact with frontal, supraocular in contact with prefrontal, two postoculars; (6) maxillary teeth 10 (4+2+2+2); (7) two anterior temporals, three posterior temporals; (8) precloacal plate entire; (9) ground color from head to tail brownish black, with 31-35 dusty rose bands on body trunk, 13-16 on tail; (10) bands in 1-2 vertebral scales broad in minimum width; (11) bands separate ground color into brownish black ellipse patches arranged in a row along the top of body and tail; (12) elliptical patches in 3-6 scales of the vertebral row in maximum width; (13) ventral surface of body with wide brownish black strip, margined with a pair of continuous narrow greyish white ventrolateral lines.

Recent phylogenetic analysis encompassing multilocus nuclear-gene and matrilineal mtDNA genealogy has revealed a series of cryptic species of the subgenus Panophrys within genus from southern and eastern China. This study demonstrates that the specimens from the hilly areas among Guangdong, Guangxi and Hunan can be morphologically distinguished from all recognized congeners, thereby providing additional supports for the recognitions of four new species of , namely Megophrys (Panophrys) mirabilis Lyu, Wang & Zhao, from northeastern Guangxi, Megophrys (Panophrys) shimentaina Lyu, Liu & Wang, from northern Guangdong, and Megophrys (Panophrys) xiangnanensis Lyu, Zeng & Wang, and Megophrys (Panophrys) yangmingensis Lyu, Zeng & Wang, from southern Hunan. The descriptions of these species take the number of species to 101, 46 of which belong to the subgenus Panophrys.

The taxonomic status of the previous record of Stuart & Chuaynkern, 2007 from Guangdong and Guangxi, southern China, is revised based on the comparison of morphological and molecular data collected from the Chinese specimens and the holotype of from Thailand and Ziegler, Pham, Nguyen, Nguyen, Wang, Wang, Stuart & Le, 2019 from Vietnam. Results reveal that the population from Shiwandashan Nature Reserve in southern Guangxi, China belongs to , and represents the first national record for China; the populations from western Guangdong and southeastern Guangxi are described as a new species, We suggest that should be removed from the Chinese herpetofauna checklist. The new national record of and the description of the new species bring the total number of to 13 in China.

The diversity of the subgenus Panophrys within the genus has been revealed to be extremely underestimated from southeastern China. Herpetological surveys coupled with extensive sampling in a longitudinal mountain belt located in southeastern China resulted in the discoveries of six new species of the subgenus Panophrys. Furthermore, the new discoveries support the findings of "micro-endemism", "sympatric phenomenon" and "sympatric but distant phylogenetically" which appear to be common among species, and also indicates that the Asian horned toads would be good candidates for studies on speciation and biogeography, and additionally emphasizes the conservation difficulties of these toads.

Target sequence capture is an efficient technique to enrich specific genomic regions for high-throughput sequencing in ecological and evolutionary studies. In recent years, many sequence capture approaches have been proposed, but most of them rely on commercial synthetic baits which make the experiment expensive. Here, we present a novel sequence capture approach called AFLP-based genome sequence capture (AFLP Capture).
