Six amphibian taxa are described within the Pleistocene vertebrate assemblage of the Taurida cave (Crimean Peninsula): Lissotriton sp., Strauchbufo raddei, Bufotes viridis, Rana cf. macrocnemis, Pelophylax ridibundus, and Pelophylax sp. The possible presence of second species of the genus Rana is suggested. Three of described species do not occur on the Crimean Peninsula currently, but apparently inhabited it during the Early Pleistocene. The ranid frogs in Crimea were taxonomically more divers in the Pleistocene than today. Strauchbufo raddei and Bufotes viridis come from different periods of sediment accumulation of the Taurida cave, during the Early Pleistocene and the late Middle Pleistocene, respectively. The presence of the Mongolian toad, Strauchbufo raddei, not previously reported from Crimea, confirms a wide distribution of this species during the Early Pleistocene of Eastern Europe. The Taurida cave represents the first Pleistocene amphibian assemblage of Crimea.

Achalinus pingbianensis Li, Yu, Wu, Liao, Tang, Liu et Guo, 2020, a species previously known only from a male collected in Yunnan Province (People’s Republic of China), is reported for the first time from Vietnam (Lao Cai Province) based on the re-examination of nine specimens deposited in the collections of the Muséum National d’Histoire Naturelle which were formerly identified as Achalinus spinalis. Furthermore, we also provide the first description of a female specimen and an expanded diagnosis of the species. The short discussion of the identification and distribution of Achalinus spinalis and A. rufescens is provided.

The distribution range of the species Trimerodytes yunnanensis is revised based on preserved specimens and literature data review. Comparing morphology, colour pattern, and classification history of Trimerodytes aequifasciatus form Myanmar (Sagaing) and T. percarinatus previously reported from northeast India (Arunachal Pradesh), Myanmar (Kachin) and Thailand (Chiang Mai) proved to be misidentifications of T. yunnanensis. Trimerodytes yunnanensis is recorded for India for the first time. We propose to remove Trimerodytes aequifasciatus from the species list of Myanmar and T. percarinatus from the species lists of India, Myanmar, and Thailand. The natural history and conservation status of T. yunnanensis is discussed. A diagnostic key for the species of the genera Trimerodytes and Isanophis is provided.

The scales of six venomous snake species from China were examined for their ultrastructure. Scanning electron microscopy was used to observe the scales, which were peeled off from the middle back of the snakes. The results revealed significant differences in the microdermatoglyphic structure patterns between the two families, Viperidae and Elapidae. Viperidae exhibited a “polygonal” structural unit, while Elapidae displayed arcs, pores, and strips as their basic structure. Additionally, there were notable differences in ultrastructure within each family. In Viperidae, Ovophis makazayazaya had a flat structural unit, Trimeresurus stejnegeri had a mound-like uplift near the center with a flat surrounding, and Protobothrops mucrosquamatus had an overall uplifted structure. In Elapidae, Ophiophagus hannah showed obvious differences in the size and arrangement of arc structures. The intraarc structure of Bungarus multicinctus resembled vertebral bodies, while that of Sinomicrurus peinani was columnar in shape. The ultrastructural characteristics of snake scales generally exhibited essential differences among advanced taxonomic units. However, there were detailed differences among species within the same family or genus. The initial formation of microornamentation features in scales may be related to the snakes’ habitat environment. Species formation through isolation is accompanied by the differentiation of these characteristics, and once species formation occurs, the features remain stable until the next species differentiation. There were instances of similar structures found in species with distant evolutionary relationships. This suggests that the microdermatoglyphic structure has taxonomic significance but may not necessarily have phylogenetic significance.

Sexual size dimorphism in snakes is closely related to mating behavior and fecundity selection. It provides important information on animal morphology and evolutionary ecology because it allows us to identify key morphological and functional traits between sexes and infer intraspecific competition. In this study, we measured the morphological characters of 147 individuals of three pit viper species stored in the archive of the National Institute of Biological Resources of the Ministry of Environment and confirmed interspecific differences and sexual size dimorphism of each species. We also identified important characters affecting identification using linear discriminant analysis. The results showed that the three pit viper species differed in body and head morphology, and the number of dorsal scale rows was the most important character for species identification. It was found that female red-tongued pit vipers and short-tailed pit vipers were larger than males of each species, while male Central Asian pit vipers were larger than females. Characters related to tail length and head length were confirmed as important characters for interspecific sex discrimination. We compared characters related to head morphology between sexes to find that red-tongued pit vipers showed differences in most characters, while short-tailed pit vipers and Central Asian pit vipers did not. Therefore, short-tailed pit vipers and Central Asian pit vipers are expected to have strong intraspecific competitive pressure. In future studies, it will be necessary to conduct a detailed research on intraspecific competition of short-tailed pit vipers and Central Asian pit vipers with little morphological differences between sexes by examining resource utilization (e.g., food sources and habitats) and ecological niche.
