“…Kukri Snakes of the genus Oligodon (H. Boie in Fitzinger, 1826) are a speciose group of colubrid snakes widely distributed across the Asian continent as far west as Turkmenistan and as far east as the Maluku Islands of Indonesia (Green 2010;Uetz et al 2020). While several species of Oligodon are locally abundant throughout their range, most species in the genus are known from a handful of specimens and are poorly understood by herpetologists (Orlov et al 2010;Supsup and Carestia 2020).…”

Oligodon hamptoni is a rare species of Kukri Snake known from only two specimens, both collected nearly a century ago in northern Myanmar. Here, we report the third record of this species based on a photograph taken in Mt. Gaoligongshan, Tengchong City, Yunnan Province, China, approximately 235 km northeast of the nearest record in Bhamo District, Kachin State, Myanmar. We also provide a detailed redescription of the holotype, showing that the photo record from Mt. Gaoligongshan can be unambiguously identified to this species. This rediscovery represents the first observation of O. hamptoni in China and is the first report of this species in almost 100 years.

We investigated the taxonomic status of the recently described kukri snake Oligodon arenarius Vassilieva, 2015 and the morphologically similar Oligodon macrurus (Angel, 1927), two species endemic to the southern coast of Vietnam. Based on phylogenetic analyses using three mitochondrial genes (12S–16S rRNA, cytochrome b), we recovered O. arenarius and O. macrurus in a clade within the O. cyclurus-taeniatus species group, agreeing with previous intrageneric classifications. Genetic distances between O. arenarius and O. macrurus are extremely low (less than 0.5% based on 12S–16S) and render O. arenarius paraphyletic. All preserved specimens of O. arenarius and O. macrurus convey little to no differences in color pattern, hemipenial morphology and osteological features; the latter of which is based on three dimensional micro computer tomography (µCT) scans of one specimen per species. Contrasting these results, univariate and multivariate analyses revealed significant differences in relative tail length, and the number of ventral and subcaudal scales between both species. Although the molecular and morphological datasets present conflicting results, integrating the evidence leads us to synonymize O. arenarius with O. macrurus. We provide a formal redescription of O. macrurus, designate a neotype specimen to avoid future taxonomic confusion, and provide the first detailed osteological description of this species. Oligodon macrurus sensu stricto is endemic to coastal dunefields and adjacent forest habitats in southern Vietnam, where ongoing human development, tourism and road mortality pose significant threats to its conservation. Consequently, we suggest that O. macrurus should be listed as “Vulnerable” based on the assessment criteria of the International Union for Conservation of Nature (IUCN).
