“…They are quite common and have radiated into various habitats. At present, more than 20 species mainly belonging to three species groups (i.e., the G. blomhoffii complex, G. intermedius-halys complex, and G. strauchi complex) are recognized Zhao 2006;Shi et al 2017Shi et al , 2018. Within Gloydius, most species having 21 rows of mid-body dorsal scales and three palatine teeth have been attributed to many subspecies of G. strauchi (Bedriaga, 1912).…”

“…monticola (Werner, 1922)) and several new species have been described from across the range of the complex (e.g., G. rubromaculatus, G. angusticeps, and G. huangi;Xu et al 2012;Shi et al 2017;Shi et al 2018;Wang et al 2019).…”

“…Given that the Gloydius strauchi complex is widely distributed in western China (Zhao et al1998;Zhao 1999Zhao , 2006, some of the specimens from previous studies are now attributable to the recently elevated species described above. The distribution of G. strauchi sensu stricto has been restricted to western Sichuan by recent molecular and morphological studies Barabanov 1999, 2000;Shi et al 2017Shi et al , 2018. With respect to Tibet, older records of the G. strauchi complex refer to at least two different species, G. rubromaculatus from Jiangda (Shi et al 2017(Shi et al , 2018 and G. huangi from Chamdo (Wang et al 2019).…”

“…Additionally, Gloydius himalayanus (Günther, 1864) has long been regarded as a full species within the G. strauchi complex based on its unique morphological characters (e.g., the conspicuous rostralis and the triangular head in dorsal view; Gloyd and Conant 1990). In spite of numerous recent studies focused on the molecular phylogeny of the genus Gloydius (Xu et al 2012;Eskandar et al 2018;Shi et al 2016Shi et al , 2018Asadi et al 2019;Wang et al 2019), the systematic and taxonomic position of G. himalayanus in relation to the G. strauchi complex is still unclear due to lack of the sequence data for this species.…”

We provide a molecular phylogeny of Asian pit vipers (the genus Gloydius) based on four mitochondrial genes (12S, 16S, ND4, and cytb). Sequences of Gloydius himalayanus, the only member of the genus that occurs south of the Himalayan range, are included for the first time. In addition, two new species of the genus Gloydius are described based on specimens collected from Zayu, Tibet, west of the Nujiang River and Heishui, Sichuan, east of the Qinghai-Tibet Plateau. The new species, Gloydius lipipengi sp. nov., can be differentiated from its congeners by the combination of the following characters: the third supralabial not reaching the orbit (separated from it by a suborbital scale); wide, black-bordered greyish postorbital stripe extending from the posterior margin of the orbit (not separated by the postoculars, covering most of the anterior temporal scale) to the ventral surface of the neck; irregular black annular crossbands on the mid-body; 23-21-15 dorsal scales; 165 ventral scales, and 46 subcaudal scales. Gloydius swildsp. nov. can be differentiated from its congeners by the narrower postorbital stripe (only half the width of the anterior temporal scale, the lower edge is approximately straight and bordered with white); a pair of arched stripes on the occiput; lateral body lakes black spots; a pair of round spots on the parietal scales; 21 rows of mid-body dorsal scales; zigzag dark brown stripes on the dorsum; 168–170 ventral scales, and 43–46 subcaudal scales. The molecular phylogeny in this study supports the sister relationship between G. lipipengisp. nov. and G. rubromaculatus, another recently described species from the Qinghai-Tibet Plateau, more than 500 km away, and indicate the basal position of G. himalayanus within the genus and relatively distant relationship to its congeners.

BackgroundBothrops atrox is a pit viper with a loreal pit organ, and its embryological development remains undescribed. Here, we provide a comprehensive description of the embryology of B. atrox, focusing on the loreal pit organ and cephalic scales.ResultsWe characterized 13 developmental stages of B. atrox based on external features consistent with the embryogenesis of previously described snake species. The loreal pit organ originates from the circumorbital region and migrates to its final position. In Crotalinae, the pit organ first becomes visible at stage 28, whereas in Pythonidae labial, pit organs appear at Stage 35. Pit organs evolved independently three times in Serpentes, encompassing Boidae, Pythonidae, and Crotalinae. Boidae lacks embryological information for pit organs. Furthermore, we observed that head scalation onset occurs at Stage 33 in B. atrox, with fusion of scales surrounding the loreal pit organ.ConclusionsThe embryology of pit organs in Pythonidae and Boidae species remains poorly understood. Our detailed embryological descriptions are critical for proposing developmental scenarios for pit organs and guiding future research on these structures.

DNA barcoding has greatly facilitated studies of taxonomy, biodiversity, biological conservation, and ecology. Here, we establish a reliable DNA barcoding library for Chinese snakes, unveiling hidden diversity with implications for taxonomy, and provide a standardized tool for conservation management. Our comprehensive study includes 1638 cytochrome c oxidase subunit I (COI) sequences from Chinese snakes that correspond to 17 families, 65 genera, 228 named species (80.6% of named species) and 36 candidate species. A barcode gap analysis reveals gaps, where all nearest neighbour distances exceed maximum intraspecific distances, in 217 named species and all candidate species. Three species‐delimitation methods (ABGD, sGMYC, and sPTP) recover 320 operational taxonomic units (OTUs), of which 192 OTUs correspond to named and candidate species. Twenty‐eight other named species share OTUs, such as Azemiops feae and A. kharini, Gloydius halys, G. shedaoensis, and G. intermedius, and Bungarus multicinctus and B. candidus, representing inconsistencies most probably caused by imperfect taxonomy, recent and rapid speciation, weak taxonomic signal, introgressive hybridization, and/or inadequate phylogenetic signal. In contrast, 43 species and candidate species assign to two or more OTUs due to having large intraspecific distances. If most OTUs detected in this study reflect valid species, including the 36 candidate species, then 30% more species would exist than are currently recognized. Several OTU divergences associate with known biogeographic barriers, such as the Taiwan Strait. In addition to facilitating future studies, this reliable and relatively comprehensive reference database will play an important role in the future monitoring, conservation, and management of Chinese snakes.
