Occidozyga shiwandashaensis was recently discovered from Guangxi Province of China. Hylarana latouchii is a widespread species in southern China, including Hong Kong and Taiwan. Both species are expected to be found in the border areas between Vietnam and China; however, no records of these frogs have been documented from Vietnam so far. We record two species of amphibians for the first time from Vietnam, namely Occidozyga shiwandashaensis from Bac Giang Province and Hylarana latouchii from Hai Phong City and Quang Ninh Province in northern Vietnam. Morphologically, the Vietnamese representatives of O. shiwandashanensis resemble the type series from China. The specimens of H. latouchii from Vietnam slightly differ from the type series from China by having a larger size (SVL 48.6–51.7 mm in males, SVL 58.4 mm in the females vs. 36.0–40.0 mm in males, 42.0–53.0 mm in females). Genetic distances between the Vietnamese records and the type specimens of O. shiwandashanensis from China varied from 0 to 1.5% (16S gene). Genetic divergences between the Vietnamese records and H. latouchii from the type locality were 2.0–2.6% (16S gene). In addition, morphological data and natural history notes of the aforementioned species are provided, based on the new records from Vietnam.

Unnecessary splitting of genus-level clades reduces taxonomic stability in amphibians

Although the differentiation of clades at the species level is usually based on a justifiable and testable conceptual framework, the demarcation of supraspecific boundaries is less objective and often subject to differences of opinion. The increased availability of large-scale phylogenies has in part promulgated a practice of what we consider excessively splitting clades at the “genus” level. Many of these new genus-level splits are predicated on untenable supporting evidence (e.g., weakly supported phylogenies and purportedly “diagnostic” but actually variable, non-exclusive, or otherwise problematic opposing character state differences) without careful consideration of the effects on downstream applications. As case studies, we critically evaluate several recent examples of splitting established monophyletic genera in four amphibian families that resulted in the creation/elevation of 20 genus-level names (Dicroglossidae: Phrynoglossus, Oreobatrachus, Frethia split from Occidozyga; Microhylidae: Nanohyla split from Microhyla; Ranidae: Abavorana, Amnirana, Chalcorana, Humerana, Hydrophylax, Indosylvirana, Papurana, Pulchrana, Sylvirana split from Hylarana; Rhacophoridae: Tamixalus, Vampyrius, Leptomantis, Zhangixalus split from Rhacophorus, Rohanixalus split from Feihyla, Orixalus split from Gracixalus, and Taruga split from Polypedates), and also address the taxonomic status of the monotypic genus Pterorana relative to Hylarana. We reassess the original claims of diagnosability and justifications for splitting and argue that in many cases, the generic splitting of clades is not only unnecessary but also destabilizes amphibian taxonomy, leading to a host of downstream issues that affect categories of the user community (stakeholders such as taxonomists, conservationists, evolutionary biologists, biogeographers, museum curators, educators, and the lay public). As an alternative, we advocate for the use of the subgenus rank in some cases, which can be implemented to establish informative partitions for future research without compromising on information content, while avoiding gratuitous (and often transient) large-scale binomial (genus-species couplet) rearrangements. We encourage taxonomists to consider the actual needs and interests of the larger non-taxonomic end-user community who fund the majority of taxonomic research, and who require a system that remains reasonably stable and is relatively intuitive, without the need for inaccessible laboratory equipment or advanced technical scientific knowledge to identify amphibian species to the genus level.

A new species of the genus Leptobrachella, L. guinanensissp. 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, L. guinanensissp. nov. is closely related to L. ventripunctata. However, there are distinct morphological differences between L. guinanensissp. nov. and L. ventripunctata, as well as three other sympatric species (L. shangsiensis, L. shiwandashanensis, and L. sungi). 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 L. ventripunctata), the absence of brown spots on the ventral surface (vs chest and belly creamy white with many scattered brown spots in L. ventripunctata), 1/3 toe webbing and wide toe lateral fringes (vs no toe webbing and no lateral fringes in L. ventripunctata), and distinct dermal ridges under toes (vs absent in L. ventripunctata). Furthermore, the dominant vocal frequencies of the new species range from 7.3 to 8.3 kHz, which is unique compared to other Leptobrachella species and represents the highest dominant frequencies ever recorded. The Shiwandashan National Nature Reserve is now home to four known sympatric species of Leptobrachella.
