“…The present ASAP analysis produced 10 unidentical species partitions, and a total of 50 species are inferred by the best partition selected. (Malnate, 1963), and H. leucomystax (David, Bain, Nguyen, Orlov, Vogel, Vu & Ziegler, 2007), further corroborates the generic status of the recently erected Sahyadriophis (Patel et al 2023). Henceforth, our genetic divergence estimation reveals the absence of a barcode gap in the dataset and further evinces cryptic diversity within Hebius venningi, H. khasiensis, and Herpetoreas xenura by taking into account their respective intra-specific genetic divergence (3.8%) and the species inferences in ASAP.…”

The review of the taxonomic status of Herpetoreas xenura species complex, based on morphological and molecular data, revealed a new species from Myanmar, which we describe as Herpetoreas davidi sp. nov. from the Rakhine Yoma Elephant Wildlife Sanctuary in Rakhine State. It is suggested to be a sister species to Herpetoreas pealii and Herpetoreas xenura sensu stricto, and can be separated from the latter species by a combination of morphological and scalation characters, and by its pattern. Another population from the Htamanthi Wildlife Sanctuary, Sagaing Region, was previously confused with H. xenura. However, as a closer examination of its morphology, shows it to be closer to Hebius khasiensis, we herein tentatively refer to this population as Hebius khasiensis, pending further molecular data confirming its taxonomic status. Consequently, we propose to temporarily remove Herpetoreas xenura from the fauna of Myanmar. Further studies, especially in the northwestern region of Myanmar, such as near border with India in Chin Hills and Naga Hills, are required. An updated key for the species of Herpetoreas is also provided.

The natricine snake genus Smithophis Giri, Gower, Das, Lalremsanga, Lalronunga, Captain, and Deepak, 2019, is represented by four species, three of which are distributed in northeast India and Bangladesh, and a single species in Yunnan and Myanmar. In the past, S. bicolor (Blyth, 1855) was said to be widespread across northeast India and Myanmar; however, recent studies have shown it to be a species complex. Here, we describe a new species of the complex from the Indian state of Mizoram that resembles S. bicolor. The new species differs in bearing a patterned dorsum, a darker venter, and moderately keeled sacral scales. Re-examination of types of S. arunachalensis Das, Deepak, Captain, Wade, and Gower, 2020, shows the presence of strongly keeled sacral keels in males, which is an important diagnostic character. A revised key to members of the genus is presented with notes on S. arunachalensis.

A new species of the genus Hebius Thompson, 1913 is described from Yingjiang County, Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province, China, based on molecular and morphological evidence. It can be distinguished from its congeners by the following set of characters: (1) dorsal scale rows 19–17–17, feebly keeled; (2) ventrals 146–151; (3) nasal complete, nostril in the middle of the nasal; (4) supralabials 9, the fourth to sixth in contact with the eye; (5) infralabials 10–11, the first 5 touching the first pair of chin shields; (6) preoculars 2; (7) postoculars 3; (8) temporals 3, arranged in two rows (1+2); (9) maxillary teeth 31, the last 4 slightly enlarged, without diastema; (10) tail comparatively long, TAL/TL ratio 0.334 in the male; (11) dorsolateral series of irregular orange or ochre yellow blotches, extending from the neck to the posterior part of the tail; and (12) venter pale orange, tips of ventrals with subrectangular black blotches. All Hebius specimens were strongly recovered as monophyletic, in which Hebius taronensis (Smith, 1940) and Hebius venningi (Wall, 1910) were monophyletic as sister to the Yingjiang County specimens. According to the p‐distance of cytochrome b, the new species differs from its congeners by 9.7–15.4%.
